Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis i
Executive summary
This analysis evaluates the effects of a rule proposed by the U.S. Department of Transportation
to change how air carriers and ticket agents disclose information about certain ancillary fees for
flights and change how certain consumers can purchase assigned seats. Ancillary fees are fees
for optional services provided by a carrier beyond passenger air transportation. The rule would
require carriers and ticket agents to show baggage fees, ticket change fees, and ticket
cancellation fees when they first show fares and schedules to consumers searching for flights.
The rule would also require carriers who charge assigned seating fees for children 13 or under to
show the fees and allow for transactability, or the ability to buy the seating, at all points of sale.
Finally, the rule would require carriers and ticket agents to provide the same ancillary fee
information to consumers buying tickets offline or on the phone.
The analysis uses a basic economic model of asymmetric information as a framework for
evaluating the proposed rule. While asymmetric information can lead to a market failure, the
significance of the resulting inefficiency and the need for government intervention depends on
several factors. In addition, mandatory disclosures can have unintended effects like crowding out
relevant information, which can create other inefficiencies. The analysis evaluates the potential
for a failure in the market for airline tickets due to information asymmetry and evaluates existing
mechanisms for providing information to consumers. Due to a lack of data and other significant
uncertainties, quantitatively evaluating the effects of the rule is not possible at this time.
The rule would yield societal benefits if it reduced deadweight loss from inaccurate price
calculations or reduced search costs. Inaccurate price calculations lead to overconsumption and
can distort consumer perceptions in ways that confer a competitive advantage to producers who
produce a lower-quality product. While we lack information to estimate benefits, we calculated a
hypothetical example range using methods from earlier rulemakings. At the same time, the rule
could lead to crowding out of other relevant information for some consumers. The potential
effect represents an offset to benefits, and it is possible that it equals or outweighs the benefits.
The primary costs of the proposed rule are the costs that carriers and ticket agents would incur
to share ancillary fee data, modify websites, and allow transactability for assigned seats for
children 13 or under. These costs include startup implementation costs as well as ongoing costs.
Third parties involved in data exchange, such as global distribution systems (GDSs) and direct-
channel companies, would incur costs as well despite not being directly regulated by the rule.
Because these entities are already starting to upgrade systems for market reasons, the cost
properly associated with the proposed rule is the cost of requiring them to upgrade earlier than
they would without the rule.

Table ES-1 summarizes the results of the analysis and the potential economic effects of the
proposed rule. Because it is not possible to quantify total benefits or total costs at this time, it is
also not possible to quantify whether the proposed rule would yield benefits that exceed costs.

Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 1
1 Introduction
The U.S. Department of Transportation (USDOT) has proposed a rule requiring air carriers and
ticket agents to change how they disclose information about certain ancillary fees for flights and
change how certain consumers can purchase assigned seats. Ancillary fees are fees for optional
services provided by carriers beyond passenger air transportation. The rule would require
carriers and ticket agents to show baggage fees, change fees, and cancellation fees when they
first show fares and schedules to consumers searching for flights. The rule would also require
carriers who charge assigned seating fees for children 13 or under to show the fees and allow
for transactability, or the ability to buy the seating, at all points of sale. Finally, the rule would
require carriers and agents to provide the same ancillary fee information to consumers buying
tickets offline or on the phone.
This regulatory impact analysis (RIA) qualitatively assesses the economic effects of the proposed
rule. The RIA examines information on the potential existence and significance of a market
failure and evaluates the benefits, costs, and distributional effects of the requirements of the
proposed rule. Due to a lack of data and other significant uncertainties, quantitatively evaluating
the effects of the rule is not possible at this time.
2 Need for regulation
The main premise underlying the proposed rule is that a market failure may exist because airline
consumers may have inadequate information about ancillary fees before buying tickets. In 2008
and 2009, legacy air carriers began unbundling the products offered to consumers, offering
lower base fares and charging ancillary fees for baggage transport and other optional trip-
related services.
1
In the following years, carriers increased these fees and introduced new types
of ancillary fees.
2
In 2020, the ten largest passenger air carriers in the United States collected an
estimated $2.8 billion in baggage fees and $900 million in change and cancellation fees.
3
The notice of proposed rulemaking (NPRM) cites reports by the Government Accountability
Office (GAO) in which the GAO concluded that some consumers may have insufficient

information about ancillary fees. The reports concluded that carriers are increasingly charging
fees for passenger services without disclosing the fees consistently. In 2010, GAO recommended
to the Department that carriers disclose baggage fees consistently across distribution channels.
4
In 2017, GAO found that airlines increased the number of optional services for which they
assessed fees. The variety of new fees, combined with packages of services sold in bundles,
made it difficult for consumers to compare prices.
5
At the same time, GAO also notes that the
airlines reported that the practice allowed them to lower base airfares for customers who
preferred not to use the services.
The Department also reviewed baggage and other ancillary fees and found that the fees vary
widely across airlines, as discussed in Section 4.1 (Baggage fees). Carriers also use different
systems for assessing fees for baggage on international flights, as described in Appendix A,
making price comparisons for international flights less straightforward.
2.1 Information asymmetry and market failure
Information asymmetry occurs when buyers and sellers in a market have unequal information
about aspects that affect the total price of a product or service. These aspects can include
monetary components such as ancillary fees or non-monetary attributes such as quality. If
buyers have less information than sellers and underestimate total price as a result, then they will
purchase more of the good at a higher price than they would if they had better information. The
equilibrium price and consumption are higher in the presence of asymmetric information. The
higher price paid causes a transfer of surplus from consumers to sellers. The transfer correlates
with additional profit for producers, who thus have a disincentive to disclose the information to
consumers. The overconsumption also leads to a deadweight loss for society because the
resources used to produce the good would have been put to a better use if consumers had
better information. Figure 1 illustrates the model.

Figure 1: Effects of information asymmetry leading buyers to overestimate quality
For airline ancillary fees, inefficiencies could arise if consumers making purchase decisions lack
information about the fees or have poor information that leads them to underestimate the fees.
In that case, consumers cannot calculate the full price of air travel, and they behave as if air
travel prices are lower than they are. In the basic asymmetric information model, the lack of
information influences consumer decisions to purchase airline tickets because it affects their
perceived price of air transportation. In the model, consumers would respond to information on
ancillary fees by reducing their purchases of airline tickets, either by not traveling or choosing
another mode of transportation.
In practice, consumers may respond in other ways because ancillary services are optional for air
travel, even if consumers often buy them. If consumers would primarily respond to an
information disclosure by not using ancillary services rather than reducing airline ticket
purchases, then the potential inefficiency from insufficient information comes from consumers
purchasing ancillary services they may not want or paying too much for them, rather than from
distortions in the price of air travel itself. With better price information, consumers may be able
to shop around, perhaps finding an airline that offers these services at lower prices. In addition,
consumers may have alternatives to paying ancillary service fees even after they purchase
airfares. For example, some travelers may be able to pack fewer items and avoid additional
checked bag fees.
Information problems can occur due to the inherent features of the product or producers might
engage in actions to create them. One method a producer can create an information advantage
is through of the practice of drip pricing, “a pricing technique in which firms advertise only part
of a product’s price and reveal other charges later as the customer goes through the buying
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 4
process.”
7
In a simple model of drip pricing, a producer creates the favorable information
asymmetry by shrouding part of the price of a product.
8
Experimental research suggests that
consumers encountering drip pricing are more likely to make purchasing mistakes if they are
uncertain about the extent of the drip pricing.
9
The point during the purchase decision that the consumer acquires the information can also
affect decision-making. For example, when a grocery store included sales taxes in its advertised
prices as part of a field experiment, people purchased fewer products despite already being
aware of the sales taxes before the field experiment.
10
Producers could also use timing to create
an information advantage, as shown in research on drip pricing. One study found that
individuals are more likely to choose a lower-price airfare when all fees are disclosed up front
rather than revealed at points during the purchase process. Even when the participants became
aware of the additional fees, they were reluctant to restart the purchase process because they
perceived high search costs and inaccurately assumed that all companies charge the same
fees.
11
Asymmetric information could also have broader market effects, as shown in the literature on
asymmetric information and product quality.
12
A lack of consumer information can create
circumstances where low-quality or otherwise inefficient producers have a competitive
advantage. This advantage could lead to adverse selection, where high-quality producers exit
the market.
In sum, the basic model of information asymmetry favoring producers identifies two primary
effects that may occur when consumers make purchase decisions without full information. The
first effect is a deadweight loss or a reduction in social surplus due to overconsumption. When

the information problem is corrected, resources supporting overconsumption become available
for better societal use, and the deadweight loss is reduced or eliminated. The second effect is
distributional because it involves a transfer of consumer surplus to producers, which a
producer’s information advantage facilitates. It is not necessary for the information to be
completely absent from the market for these effects to occur; information that is ambiguous or
time-consuming and costly to obtain will have similar effects. Resolving information asymmetry
can counter consumer issues and give rise to secondary effects like improved product quality or
increased productive efficiency as producers respond to consumer changes in purchasing
behavior.
2.2 Addressing inadequate or asymmetric information
If the cost of providing the information to the consumer is lower than the deadweight loss due
to the consumer’s lack of information, then the market solution will be inefficient. Efficiency
could be enhanced by disclosing the information to the consumer, possibly through
government intervention requiring the seller to supply it. At the same time, the additional profits
that the seller earns from favorable information asymmetry act as an incentive for third parties
to enter the market. Third parties might supply the information as long as the cost of providing
that information is lower than the price consumers are willing to pay for it. The entry of third-
party information suppliers could correct the inefficiency without government intervention.
The basic asymmetric information model assumes that providing information is sufficient to
reduce information asymmetry and improve consumer decision-making. If the added
information is redundant, unusable, or ignored by consumers, however, consumers will continue
to behave as if the information were not provided. In some cases, excess information can create
or exacerbate information asymmetry. “Crowding out” occurs when individuals become
overwhelmed with information and do not pay attention to the most salient information.
13
Crowding out could increase deadweight loss if it leads consumers to make worse decisions.
Consumers also can sometimes acquire information on their own and are likely to do so when
search costs are lowlow, at least, relative to the price of the good or service. When consumers
can easily acquire the information needed to evaluate the full spectrum of price and quality
combinations in the market, they can eliminate the asymmetry through their own actions, albeit
with the cost of additional time and effort. Homogeneity of a product or service is one reason
search costs might be low because consumers can acquire information without repeated price
comparisons. Additionally, if consumers purchase the product or service frequently, then they
can passively acquire knowledge over time.

Circular A-4 from the Office of Management and Budget identifies several factors for agencies
to consider when proposing regulation to address inadequate or asymmetric information.
14
We
examine these factors in Section 7.1 (Baseline for analysis).
3 Rulemaking history
In May 2014, the Department issued an NPRM addressing a variety of aviation consumer
protection issues (Consumer Rule III).
15
One provision proposed requiring carriers and ticket
agents to disclose baggage fees and seat assignment fees on the first page of search results for
flights. The baggage fee requirement applied to carry-on and first and second checked bags. In
January 2017, the Department issued a supplemental notice of proposed rulemaking (SNPRM)
limiting the proposed disclosures to baggage fees but withdrew it in December.
16
The current NPRM expands upon the 2014 and 2017 rulemaking actions by proposing to require
carriers and ticket agents to disclose baggage fees, cancellation fees, and change fees on the
first page of search results. The NPRM further proposes to require carriers and ticket agents to
show seat assignment fees for consumers traveling with children 13 years or under and allow for
transactability, or the ability to buy assigned seats, at all points of sale.
4 Ancillary fees for domestic carriers
Department regulations currently require carriers to disclose all ancillary fees on a prominent
link on their homepage.
17
Carriers must also include baggage fee information for carry-on bags,
first checked bags, and second checked bags on e-ticket confirmations.
18
While carriers can
show some fees as a range, they must show baggage fees as specific amounts and account for
factors like frequent-flyer status that affect the fees.

This section assesses the state of ancillary fees for the largest domestic carriers in the United
States. We examine carriers who must report certain financial data and on-time performance
data to the Department because they have at least 0.5% of total domestic passenger revenues.
4.1 Baggage fees
Baggage fees on domestic flights vary widely across airlines, even within the same flight class
(Table 1). Ultra-low-cost carriers (ULCCs), which have low base fares and rely on ancillary fees for
most of their revenue,
19
have the highest baggage fees and the most variation in fees. ULCCs
also charge for carry-on bags while most other carriers do not. Baggage fees can also vary by
individual: passengers with frequent-flyer memberships, credit-card bonuses, military or veteran
status, or other characteristics may have reduced fees or no fees.
Consumers can find baggage fee information on carrier websites, although accessing the
information may interrupt the booking process. Consumers may also need to enter information
in a baggage fee calculator. While most airlines charge the same baggage fee for an itinerary
regardless of connecting flights, at least one airline (Spirit) charged different fees on direct
flights versus flights with connections.

Baggage fees vary more on international flights, as summarized in Appendix A. Moreover, the
systems carriers use to assess fees on these flights vary considerably. Among the nine carriers
reviewed which offer international flights, two do not charge baggage fees, three charge the
same baggage fees as they charge domestic flights, two charge by region and country, and two
require specifying an itinerary.
4.2 Ticket change and cancellation fees
Airlines charge varying fees for changing a ticket (Table 2) or cancelling a ticket (Table 3). Some
mainline carriers have introduced basic economyflights with cheaper airfares than regular
economy-class flights but with more restrictions on seat selection, ticket changes, and
cancellations. USDOT regulations require carriers to allow all consumersregardless of flight
classto cancel tickets for no charge within 24 hours of purchase or hold a reservation without
payment for 24 hours, depending on carrier policy.
In response to the COVID-19 public health emergency, airlines have also introduced new change
and cancellation policies allowing passengers to cancel or change flights for free. Some airlines
state that they have permanently removed change or cancellation fees for passengers in all
flight classes except basic economy. Instead, passengers can cancel flights and receive vouchers
for future travel in the amount of the original ticket price. Consumers can also purchase travel
insurance or a refundable class of airfare to avoid change and cancellation fees.

4.3 Seat assignment fees and family seating policies
Most carriers charge people to select seats before the flight if they fly basic economy or wish to
sit in certain main-cabin seats (Table 4). Seat assignment fees typically vary by seat location:
window and aisle seats cost more than middle seats, and seats closer to the front cost more
than seats toward the back. Some carriers also offer economy-class seats that are slightly larger
or offer extra leg room. Buying assigned seating for these seats may require passengers to
purchase a bundle with other ancillary services.

Carriers have different seating policies for families who travel together without buying assigned
seats. Most carriers try to place children next to parents using multiple methods. Carrier seat
assignment systems detect families traveling together if they are on the same reservation and
search for adjoining seats before the day of departure. If that method does not work, then gate
agents may be able to seat families together before the flight.
Carriers display information on family seating to different degrees. American and United, for
example, explicitly discuss their family seating policies on traveling with childrenpages.
20
Other airlines discuss their policies for traveling with infants, young children, and
unaccompanied minors but do not discuss how to ensure that families sit together.
The Department’s Office of Aviation Consumer Protection provides advice for families traveling
with small children on its website.
21
The website also provides detailed information on family
seating policies for individual airlines, including links to policies when available. However, the
information is limited to general guidance on how families can sit together and does not include
information on seat assignment fees.
4.4 Re-bundling of airfares
Some air carriers have moved toward re-bundling ancillary services in various combinations and
offering discounts for buying the bundled services. Appendix B describes how airlines have
created several types of bundled fares that incorporate ancillary services such as baggage
transport and seating selection. Bundles also offer varying options regarding ticket changes and
refunds. The availability of bundles depends on fare class. For “basic economy” tickets, some
carriers limit the services consumers can buy or allow bundle purchases only within 24 hours of
departure.

Bundled services are tools for airlines to cater to specific consumers in a market.
22
Carriers that
offer bundles tend to offer them with fares included in the price. A consumer purchasing a
bundle receives only the included services and cannot select additional services for a fee. While
preselected services may reduce consumer flexibility, they may also save time and reduce
complexity for some passengers.
The proposed rule would allow a carrier or ticket agent to display the price of bundles with fares
included, but airlines might need to adjust how they display bundles to ensure that the
consumer understands which services are included in the bundles.
5 Requirements of the proposed rule
This section summarizes the provisions of the proposed rule (Table 5). The NPRM contains
authoritative descriptions of each provision and discusses them in detail.

Summary
Baggage fees
Carriers and ticket agents must display the applicable fees for one
carry-on bag and first and second checked bags on the first page
displayed when a consumer searches for air transportation. The
displayed fees must be modified for frequent flyer status or other
passenger characteristics affecting fees if the consumer provides
this information.
Ticket change and cancellation
fees
Carriers and ticket agents must display ticket change and
cancellation policies and fees on the first page displayed when a
consumer conducts a search for air transportation. The fees
displayed must be modified for frequent flyer status or other
passenger characteristics affecting fees if the consumer provides
this information.
Family seating fees
Carriers and ticket agents must display information about fees
for children 13 and under to sit next to an accompanying adult
in the same class of service.
If carriers charge fees for assigned seating for children 13 and
under, carriers and ticket agents must allow consumers to
purchase the assigned seating at all points of sale

Summary
Additional policies
Carriers giving fare and schedule information to ticket agents
must also give information on fees for carry-on bags, first and
second checked bags, ticket changes, ticket cancellations, and
seat assignments.
Carriers and ticket agents must disclose to consumers
purchasing tickets offline that ancillary fees apply and must
provide exact fees.
Carriers and ticket agents may display prices with ancillary fees
more prominently than prices with only mandatory charges.
Terms like ancillary service feeare defined for rulemaking.
5.1 Baggage fee information
The proposed rule would require carriers and ticket agents to display the fee for a first checked
bag, a second checked bag, and a carry-on bag on the first page displayed after a search for
flights. The fees must reflect the selected itinerary and fare category and must show weight and
dimension limitations for each bag. Carriers and ticket agents could display the baggage fees
separately or combined with the fare. Carriers and ticket agents would no longer need to
provide the original accompanying notice.
If the carrier or agent website shows multiple fare categories for the same itinerary (Figure 2),
the proposed rule requires the carrier or agent to show the associated baggage fees beside
each fare displayed. Consumers would have the option to conduct a passenger-specific itinerary
search, which would adjust the fees based on passenger characteristics like frequent-flyer status.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 13
Figure 2: Carrier website (United) showing multiple fare categories, May 2022
5.2 Ticket change and cancellation fees
Carriers and ticket agents may currently place ticket cancellation and ticket change policies on
various parts of their websites to meet disclosure requirements. The proposed rule would
require carriers and ticket agents to display applicable ticket change fees and cancellation fees
on the first page displayed after a search for flights. The carriers and ticket agents would also
need to provide summaries of their 24-hour hold and cancellation policies before the consumer
can buy or reserve tickets.
5.3 Family seating fees
Carriers and ticket agents are currently not required to inform consumers of the carrier’s family
seating policies. The proposed rule would require carriers and ticket agents to display fees for
seat assignments beside search results for fares if the passengers are traveling with children 13
or under and the carriers charge fees to select seats for passengers in that age group.
The provision also requires carriers to allow passengers to purchase seat assignments on ticket
agent websites displaying seat assignment fees. The ability to purchase an ancillary service
directly is known as transactability. The requirement for transactability applies only to non-free
seat assignments for families traveling with children. If airlines do not charge for seat
assignments for families traveling with children, or if airlines do not allow passengers to
purchase tickets through travel agents, then airlines would not be required to make seat
assignments available through ticket agents.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 14
5.4 Additional policies
The proposed rule contains additional provisions related to ancillary fee information. These
provisions include requirements for ticket agents and options for displaying fees.
While carriers must provide ancillary fee information on their websites, they are not currently
required to provide information directly to ticket agents. The proposed rule would require
carriers to provide ticket agents withuseable, current, and accuratebaggage fee rules for a
first checked bag, a second checked bag, and one carry-on bag. Carriers would also need to
provide rules for change fees, cancellation fees, and family seat assignment fees.
For consumers buying tickets offline (by phone or in person), the proposed rule would require
carriers and ticket agents to disclose that baggage fees, change fees, cancellation fees, and
family seat assignment fees may apply. Carriers and ticket agents would need to state the
specific amounts for the fees, adjusted for passenger characteristics like frequent-flyer status,
and would need to allow consumers to purchase family seat assignments during the phone call
or in-person visit.
Finally, the proposed rule would allow airlines or agents to display a fare including all mandatory
and ancillary charges more prominently than a fare including only mandatory charges. In either
case, fares displayed must include the entire price paid by the customer for air transportation;
individual charges within the price cannot appear more prominently.
6 Travel booking industry structure
Air carriers sell tickets to passengers through multiple channels (Figure 3). Carriers sell some
tickets through direct channels but sell more tickets through travel agents and online travel
sites.
Carriers and travel agents typically interact in a two-sided market through an intermediary
platform offered by a Global Distribution System (GDS) company. Carriers provide fare
information to GDS companies through ATPCO (Airline Tariff Publishing Company). Ticket
agents use GDS to find and buy flights, as well as related items like hotels and rental cars. Online
travel agencies like Expedia or Travelocity use GDS to allow passengers to find and buy flights as
well. Carriers pay GDS companies to display their available seats in search results, while ticket
agents receive payment as incentive to use the systems. The systems used by carriers, ATPCO,
and GDS companies to exchange data may rely on legacy data formats that do not allow for
displaying information regarding ancillary services.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 15

Adapted from Daniel L. Rubinfeld. 2014. Report of Daniel L. Rubinfeld [on behalf of Airlines for America].
https://www.regulations.gov/comment/DOT-OST-2014-0056-0785
.
Technology companies that allow air carriers and ticket agents to buy and sell seats directly
from each other have emerged as competitors to GDS. We refer to these companies as “direct-
connect companies.These companies can offer more capabilities than traditional GDS
companies, including support for displaying ancillary fees. Direct-connect companies have
contributed to an increase in tickets booked directly through carriers rather than GDS. A 2021
aviation industry consulting report estimates that direct-connect bookings will account for 56%
of total bookings by 2023.
23
The IATA (International Air Transport Association) has launched a data exchange framework
known as New Distribution Capability (NDC), which offers more capabilities than traditional data
formats used by GDS companies, including support for displaying ancillary fees.
24
Direct-connect
companies have used NDC to provide services to carriers. GDS companies have begun offering
NDC-enabled services to carriers as well, although the services are still in their pilot stages and
limited to selected airlines.
Currently, carriers and ticket agents negotiate contracts to allow for data exchange such that
passengers can buy ancillary services while booking. Individual airlines and major ticket agents
typically negotiate contracts among themselves and share data through third parties such as

ATPCO. The provision on transactability would make these data exchanges mandatory if airlines
wish to charge fees for seat assignments involving children.
7 Economic effects of the proposed rule
The simple model of asymmetric information, described in Section 2 (Need for regulation),
provides a framework for assessing the potential costs, benefits, and transfers associated with
the proposed rule. The effects of the proposed rule depend on whether the rule increases the
amount of information consumers can access and whether the information improves consumer
comprehension of fees, facilitates comparison shopping, reduces search costs, or otherwise
allows consumers to make choices that increase their welfare. The proposed rule could increase
economic efficiency if it improves consumers’ price calculations and the reduction in deadweight
loss exceeds the cost of supplying the information. It may also facilitate price comparisons by
consumers, increase competition among sellers, and put downward pressure on prices for
airfares and ancillary fees. At the same time, the information could have unintended effects like
overwhelming some consumers or crowding out other information. Due to a lack of data, our
assessment is primarily qualitative.
7.1 Baseline for analysis
The baseline level of ancillary fee information available to consumers includes the information
currently provided by the airline industry, the government, and other third parties. Department
regulations already require carriers to display some ancillary fee information through a link on
the homepage. While information on family seating policies is not similarly regulated, the
Department and some carriers provide information on their websites, as discussed in Section 4.3
(Seat assignment fees and family seating policies).
In limited cases, carriers may display certain ancillary fees prominently enough to satisfy the
requirements of the rule already. Southwest, for example, advertises on its search results that the
first two bags are free and clearly states that it does not charge certain types of ancillary fees
other airlines charge.
Consumers also can book flights through third-party travel services, which provide varying
amounts of ancillary fee information. Some services provide information on ancillary fees more
readily than carriers do. On Google Flights, for example, a passenger can use filters shown after
the initial search to adjust prices based on the planned number of carry-on and checked bags
(Figure 4).
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 17
Figure 4: Google Flights search result incorporating baggage fees, May 2022
The degree to which consumers use existing information on ancillary fees is unknown. In some
cases, consumers may not know how to access the information, especially if it is not readily
available during the ticket booking process. In other cases, consumers may incur costs to search
for the information. For this reason, we primarily evaluate the proposed rule in terms of how it
may change comprehension of ancillary fee information and consumer search costs.
7.2 Benefits
While significant amounts of ancillary fee information exist in the baseline, the proposed rule
could yield societal benefits under two conditions. First, the required disclosures would need to
affect displays of information in ways that improve consumer comprehension of prices.
25
One
example is if consumers currently gain awareness of some fees, like cancellation or adjacent
seating fees, only after making their purchase decision. Second, even if the information is not
necessarily new, better and more timely comprehension could help consumers calculate prices
more accurately, which in turn would influence their purchase decisions. As described in “Need
for regulation,” economic efficiency could be improved if the disclosures reduce the deadweight

.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 18
loss created by asymmetric information or the resources spent to acquire information on
ancillary fees. In addition to efficiency effects, distributional effects favoring consumers could
occur if the better-informed consumers can purchase services at lower prices. These consumer
effects need to be compared with the resources needed to comply with the requirements of the
proposed rule to assess net impacts to efficiency, or net benefits.
USDOT has evaluated these types of expected benefits in the context of full-fare advertising for
Consumer Rule II, which requires carriers and ticket agents to show fares with all taxes and fees
included.
26
The economic analysis evaluated benefits for passengers who would improve their
price calculations with better information and for passengers who would spend less time visiting
websites to compare prices.
27
The ancillary fees considered in this proposed rule differ because
they may be more easily avoided than taxes and fees. Nonetheless, applying a similar analysis
for this rule is useful for identifying data gaps and benchmarking the level of potential benefits if
information on key parameters were available even if the results are too uncertain to apply in a
formal comparison of benefits and costs.
7.2.1 Reductions in deadweight loss
The analysis for Consumer Rule II used a consumer surplus methodology to approximate the
deadweight loss associated with consumers not incorporating full information about airfare
taxes into their purchasing decisions. The analysis estimated lost consumer surplus using a price
elasticity of demand calculated by IATA (International Air Transportation Association), average
airfares, and estimates of the fees. The analysis estimated that full-fare advertising would
eliminate about $5.8 million in deadweight loss (in 2011 dollars) if the disclosed taxes accounted
for 5% of total airfare.
Using the price elasticity of demand for air travel to calculate reductions in deadweight loss
assumes that consumers who make improved price calculations reduce purchases of airline
tickets instead of selecting a different, lower-priced itinerary. For this reason, this approach may
not accurately reflect the reduction in deadweight loss due to the full fare advertising rule.
28
For the proposed rule, we use the methodology from the Consumer Rule II analysis to provide a
hypothetical example of potential benefits from improved price calculations. The example in
Table 6 assumes that the proposed rule would encourage an additional 1% of passengers

measured provisionally by enplanements
29
to compare prices and reduce their consumption of
airline tickets as a result. It also assumes that the comparison improves their price calculation
such that the amount of ancillary fees revealedby the disclosure adds 5% to the fare those
consumers use to make their purchase decisions. In this hypothetical example, $1.1 million in
deadweight loss would be eliminated, for a benefit of $0.16 per passenger.

information to estimate the percentage of passengers who would benefit from comparing prices
or the percentage increase from the base fare the ancillary fee disclosure would reveal. Table 7
shows a matrix of annual estimated benefits from varying the two percentages.
29
Passenger enplanements measure passengers on individual flights and therefore treat a passenger
taking connecting flights on a one-way itinerary as multiple passengers. We do not have information to
estimate the degree to which passenger enplanements overestimate the number of one-way passengers,
although many passengers do not take connecting flights.

The potential per-passenger benefits range from $0.01 if the revealed ancillary fees add 1% to
the ticket price to $0.24 if the revealed fees add 6% to the price (Table 8).

As noted, this calculation of reduced deadweight loss rests upon the assumption that the
ancillary services represent an inherent component of air travel and that the demand curve for
air travel is appropriate for measuring benefits. Once consumers purchase a ticket, however,
they may be able to avoid ancillary service fees in some circumstances by not using the services
after they become aware of the fees. As described in the NPRM, for example, the 2017 GAO
report found that, after airlines imposed checked baggage fees, the number of checked bags
per passenger declined and the number of carry-ons increased. The price elasticity of demand
for air travel is not the appropriate parameter for evaluating benefits for unpurchased ancillary
services. Instead, we would need data to estimate the demand for the individual ancillary
services themselves. Because we do not know how many passengers avoid fees by not using
ancillary services and lack other key data, these calculations are illustrations rather than
estimates.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 21
7.2.2 Reductions in search costs
Consumers who search for full fare information and compare ticket prices among carriers
benefit if the proposed rule saves them search time. Such benefits are quantifiable when
information on time savings and the value of time for passengers is available. Our discussion of
potential time savings benefits is only illustrative, however, because we do not have an estimate
of the search time savings. Time savings for individual passengers would also differ based on the
websites used and the itineraries searched.
For full-fare advertising, the analysis for Consumer Rule II used a value of time for air travelers
derived from USDOT data and assumed a time savings of 5 minutes per online transaction. The
analysis calculated that, for an estimated 1.8 million online transactions, the rule would result in
time savings of $3.5 million (in 2011 dollars), resulting in an average savings of about $2.00 per
passenger search.
Table 9 shows example annual benefits for the proposed rule if 1% of passengers compared
prices before the proposed rule and those passengers save 2 minutes of searching after the rule.
We assume that passengers search for fares on their own time without compensation and
estimate the value of this time using the median post-tax wage for United States workers, which
was $22.00 per hour in 2021. In this example, the rule would result in $4.9 million in total search
cost savings, or $0.73 in time savings per passenger. This method of valuing a decrease in search
costs could be applied to an increase in search costs as well.

7.2.3 Other benefits
Consumer advocates have expressed concerns that the ancillary fees often surprise consumers.
Passengers who are surprised could experience disutility from the unplanned expenses and
could encounter delays when checking in at the airport if they are unprepared for the fees.
Better information would reduce surprises and their associated costs.
Similarly, passengers traveling with children 13 or under who do not purchase assigned seats
may experience stress prior to the flight due to uncertainty that a carrier will be able to
accommodate a need for adjacent seating. The transactability requirement will provide
passengers traveling with children 13 or under an additional opportunity to assure they are
assigned seats next to their children prior to departure, which will reduce this stress. Ticket
agents who book tickets for the consumers would also save time by being able to purchase the
assigned seating directly instead of contacting a carrier or visiting its website. The number of
potentially affected consumers or ticket agents is unknown.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 23
Finally, consumer responses to improved fee information could serve as source of market
feedback that encourages producers to offer higher-quality products or produce at a lower cost.
7.2.4 Offsets to benefits
Circular A-4 from the Office of Management and Budget directs agencies to consider the
countervailing risks of a rule in addition to its direct benefits and costs.
30
A countervailing risk is
an adverse consequence of a rule not already accounted for in the direct costs of the rule. While
one can treat countervailing risks as costs, we treat them as offsets to benefits or subtractions
from benefits, as suggested by Circular A-4. If the offsets outweigh the benefits, then the
proposed rule would create disbenefits overall.
In the case of disclosures, more information is not always better. When consumers have access
to substantial amounts of information, there is a risk that mandated disclosures could displace
other information relevant to a consumer’s decision and increase search costs. In addition, if the
mandated disclosures lead consumers to make other mistakes in assessing prices, then the
additional information could create the same types of problems as a lack of information.
Industry commenters responding to the 2014 NPRM, which proposed to require disclosing
baggage and seat assignment fees on the first page of search results, raised concerns that the
requirement would crowd out information due to limited screen space, especially for mobile
phone users.
31
Requiring carriers to display ancillary fees prominently may reduce space to show
other items of interest, like alternative flight options (Figure 5). Reducing space could increase
search costs for passengers by requiring them to interact with the page and scroll down for
information. Other users could miss the information if they fail to scroll. However, a 2018 user
experience study from the Nielsen Norman Group collecting eye-tracking data from people
viewing websites shows that they are willing to scroll past the first screenful of content to gather
information, although they spend much less time on the following content.
32
We do not have information on the size of the potential offsets relative to the benefits of the
proposed rule. It is therefore not possible to determine whether the required disclosures, on net,
reduce deadweight loss or search costs.

7.3 Costs
Carriers, ticket agents, and other firms involved in ticket booking could incur costs due to the
proposed rule because they may need to reprogram booking systems to exchange and display
ancillary fee information. Carriers already provide information on ancillary fees but may need to
alter how they display the informationand, in the case of seat assignment fees for people
traveling with children, how they allow purchases as well. Carriers, ticket agents, and other firms
could also incur costs to renegotiate existing contracts for information sharing and
transactability.
7.3.1 Costs for carriers
For carriers, the costs of disclosing ancillary fee information include implementation costs and
ongoing costs to distribute ancillary fee information to ticket agents, whether through GDS via
ATPCO, NDC, or otherwise. The 2017 SNPRM analysis estimated that most carriers marketing to
customers in the United States in 2018 would incur start-up costs to distribute the information,
with a few having no costs because they already have the capability to provide ancillary fee data
via NDC. The number of carriers capable of providing NDC data has increased since 2017: as of
May 2022, at least 101 airlines around the world, including American, Delta, Southwest, Spirit,
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 25
and United, can provide NDC data.
33
Carriers would also incur costs to change the display of
their websites to meet the requirements of the proposed rule. Finally, carriers would incur costs
to share information on ancillary fees with ticket agents for consumers buying tickets in person
or by phone.
The provision would result in startup costs for carriers, ticket agents, and intermediary parties
like ATPCO to set up data exchanges if they do not already have agreements to exchange data
for seat assignment fees and selection. These startup costs include developing and testing
technology to exchange data, as well as costs to develop and test internal company procedures.
Airlines would also incur ongoing costs to maintain and update seat fare information.
The 2017 SNPRM analysis estimated total implementation costs for carriers if half or if two-
thirds had costs of $1,000,000 and the remaining carriers had costs of $500,000, although the
analysis did not provide a rationale for using those shares. The total estimated costs ranged
from $83 to $92 million. The analysis stated that the Department expected the amounts to be
lower and asked for comments because the original comments were in response to a proposed
rule involving transactability.
Another estimate of costs for disclosing ancillary fees comes from a study in 2014 prepared for
Airlines for America as part of a response to the Consumer Rule III NPRM.
34
The study surveyed
five major airlines about the costs they incurred to comply with the requirements of Consumer
Rule II, which requires airlines to distribute baggage fee information to travel agents and update
their websites to display baggage information. The five airlines were American, Alaska, Delta,
Southwest, and United, with Southwest excluded from the reported results because it uses a
different model for ancillary fees.
Carriers reported an average cost of $3.6 million in the first year and $7.2 million over a ten-year
analysis period to exchange baggage fee information with ticket agents. To update carrier
websites with baggage fee information, carriers reported an average cost of $7.0 million in the
first year and $18.4 million over a ten-year analysis period. The costs for exchanging and
updating ancillary fee information for seat assignments are likely to be higher because the
exchange also requires support for dynamic pricing, where pricing and availability change due
to other passengers buying seats.
These cost estimates related to the baggage fee requirement allow for a lower-bound estimate
of costs for setting up displays of ancillary fees and transactability for seat assignments.

January 2014 to January 2022), the per-carrier costs to exchange information would be $4.3
million in 2022 dollars for the first year and $8.7 million for the ten-year analysis period. If the
nine largest domestic carriers excluding Southwest incurred similar costs, the total estimated
costs would be $38.7 million in the first year and $77.9 million over a ten-year period.
Intermediaries and ticket agents would also incur costs to process and display data.
A provision to transmit and disclose information on seat assignments for families may also
increase the time needed to process and load search results for passengers. This cost would
apply to all passengers until they disclose during the booking process that they are not traveling
with children. In some cases, passengers may disclose it before search.
The Airlines for America study estimated costs of wait time for seat assignment fee information
by assuming that such a provision would apply to all passengers and would add approximately
20-40 seconds to each itinerary search. The study estimated that a provision would cost
approximately $805 million per year. Because the current provision applies to fewer passengers
and because technologies to exchange information have evolved in the intervening eight years,
the degree to which the estimates of time costs remain applicable is unknown. The Department
seeks additional comment on this issue.
For ongoing costs of sharing ancillary fee information, the 2017 SNPRM analysis estimated that
each carrier in the United States would spend 8 additional labor hours a year providing
information on baggage fees. The estimated hourly labor cost was $94.57, based on an estimate
provided by a carrier in response to Consumer Rule II, for an estimated annual cost of
approximately $160,000. In the Airlines for America study, however, carriers stated that they
devoted “the equivalent of at least one full-time employee” to share baggage fee information.
Because we do not have further information to assess ongoing costs, we instead provide an
example calculation if carriers would need one full-time employee, working at 2080 hours a year,
to provide information for the new ancillary fee disclosures and assigned seat transactability.
Using these estimates and adjusting the 2017 SNPRM hourly labor costs for inflation (from
$94.57 in 2017 to $101.87 in 2021), the nine largest domestic carriers excluding Southwest
would incur an estimated labor cost of approximately $1.77 million (Table 12).

7.3.2 Costs for GDSs and direct-connect companies
While the proposed rule does not impose direct requirements on GDSs, they would need to
upgrade their systems and data-sharing arrangements so that ticket agents using GDSs can
show ancillary fees on their websites as required by the proposed rule. Direct-connect
competitors would similarly incur implementation costs, but their costs would be lower if they
already exchange data with the NDC format, which supports ancillary fee information.
The 2017 SNPRM analysis noted that GDSs already began efforts to exchange ancillary fee data
with carriers for market reasons unrelated to the proposed rule. GDSs now tout their adoption of
NDC, and ATPCO advertises a platform toaccelerate NDC industry implementation.
35
Because
GDSs are already starting to upgrade systems, the cost properly associated with the proposed
rule is the cost of requiring GDSs to upgrade earlier than they would without the rule, which is
less than the total cost of upgrading systems.
7.3.3 Costs for ticket agents and metasearch sites
Like carriers, ticket agents with websites displaying airfares would incur costs to modify or
upgrade systems to display ancillary fees and allow transactability. Metasearch sites that display
airline flight search options but do not sell airline tickets would incur costs to display the
ancillary fees but not to allow transactability. Ticket agents would also incur costs to maintain
usable, accurate, and up-to-date information on ancillary fees for consumers contacting them in
person or by phone. We do not have information to estimate these costs.
7.4 Comparison of benefits and costs
The societal benefits of the proposed rule depend on whether the proposed rule facilitates
consumer comprehension of ancillary fees or reduces their search costs. The degree to which
the proposed rule generates benefits is unclear due to a lack of information and due to
uncertainty regarding the existence or magnitude of potential offsets from potential crowding
out of relevant information.
While industry is already disclosing the required information required to a large degree, we
expect that carrier and ticket agents will need to adjust how they display price information. The
primary costs of the rule involve adjustments in programming and display of information. The
costs for GDSs and other ticket agents are highly uncertain because it is unclear how the rule
would change their displays of airline ticket prices and what types of upgrades they would need
to conduct.

Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 28
7.5 Distributional effects
The basic model of asymmetric information also identifies a key distributional effect involving
producers and consumers. This effect arises because there is a transfer of consumer surplus to
producers who exploit an information advantage. When the information advantage is
eliminated, the captured surplus returns to consumers. Like societal benefits, the extent of the
transfer depends on whether the proposed rule improves information for consumers. More
specifically, improvements in information could allow consumers to reduce purchases of
ancillary services that they do not want or need or to uncover lower price options through
comparison shopping.
8 Uncertainties
The baseline level of information that passengers have on ancillary fees is substantial, but we do
not have information on how passengers use the information to calculate total prices or how
well they understand ancillary fees overall. Some consumers may have developed increased
awareness of ancillary fees due to experience with bookings and information from air carriers,
consumer advocacy groups, media, and government. An accurate assessment of the effects of
the proposed rule would consider a baseline that includes consumer adaptations to industry
practices, but we do not have data to measure how consumer awareness has changed.
Our ability to estimate benefits and costs is limited due to other significant uncertainties. We do
not have data on the amount of search time the proposed rule is expected to save or the
amount that consumers underestimate airfares due to the lack of information on ancillary fees.
We also do not have current information to assess the costs that carriers, global distribution
systems (GDSs), and direct-channel companies would incur to share ancillary fee data, modify
websites, and allow transactability for assigned seats for children 13 or under. The airline
industry may have some of this information from user experience research, market studies, or
previous technology initiatives.
Finally, because we cannot estimate overall benefits, costs, and net benefits, other potential
economic effects of the proposed rule are also unknown. These include the ultimate effects on
airfares as well as any secondary effects like impacts to ancillary fees, ancillary services, or
contracts between carriers, ticket agents, and other firms.
If the technology and search costs are high enough, then airlines may respond by ending the
practice of charging seat assignment fees for families. Airlines may further respond by changing
ancillary fee charges, changing base fares, or assessing new ancillary fees. We do not have
information on the amount of revenue airlines currently collect from seat assignment fees from
families traveling with children, although seat assignment in general is the second largest source
of ancillary fees after baggage. Information is not currently available to assess the potential
effects of such a shift in pricing on ancillary fees or base ticket prices. These changes would also
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 29
have distributional effects if they changed the amounts that different groups of passengers
(families with children; people traveling without children) pay in ancillary fees to airlines.
The effects of requiring transactability on contracts between airlines and ticket agents is
unknown. Airlines solicit bookings through travel agent services but also maintain their own
booking sites. Airlines collect fares, ancillary fees, and other ancillary revenues such as hotel
commissions from passengers who book directly through their website.
The Department seeks information to reduce the uncertainties in this analysis. In particular, the
Department seeks comments on the potential implementation costs of the proposed rule and
the potential changes on consumer search costs and decision-making.
Table 13 summarizes the key uncertainties for quantifying or monetizing the economic effects of
the proposed rule. The Department seeks comments and information that would help with
quantifying the effects. The same uncertainties that prevent estimating primary effects also
preclude assessing potential secondary effects, including effects on airfares, ancillary fees, or
GDS contracts with carriers and ticket agents. Given the overall lack of data, it is not possible to
make an economic judgment at this time about potential secondary effects.

9 Regulatory alternatives
In developing the NPRM, USDOT considered two alternative proposals. One proposal
considered an alternative display for family fees. Another proposal considered different display
requirements for baggage versus change and cancellation fees.
9.1 Displaying maximum seating fees for family seating
USDOT considered alternative family seating provisions that would require carriers and ticket
agents to show the maximum seat assignment fees that passengers could pay to ensure that
they had adjoining seats. If the fees increase after booking, carriers and tickets would need to
show the maximum fees at any point before the flight. Because these amounts may not reflect
what most consumers would pay in practice, such disclosures could be confusing to consumers.
For this reason, USDOT rejected this alternative in favor of a requirement that allows consumers
to purchase seat assignments directly from ticket agents.
9.2 Displaying fee information on the final page
USDOT considered displaying ticket cancellation and change fee information on the final page
before booking rather than the first page of search results. This regulatory alternative would
result in a smaller reduction of search costs for the information. At the same time, it would also
be less likely to displace trip information from the first page of search results. For this reason, it
is unclear whether the policy alternative would reduce overall search costs relative to the
selected policy. In addition, the alternative would not meet the policy objective of assuring that
that the consumer has information early in the purchase process.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 31
10 Summary
Consumers have access to substantial amounts of information on ancillary fees and family
seating policies through carrier websites, ticket agents, and third parties, although the ease with
which they can access the information is unknown. The existence of this information suggests
that the potential for market failure due to a lack of information alone is limited. We therefore
evaluate the proposed rule in terms of how it may change consumer search costs and
comprehension of ancillary fee information. Table 13 summarizes the expected economic effects
of the proposed rule.

Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 32
The primary costs of the proposed rule are the implementation costs that carriers and ticket
agents would incur to share ancillary fee data, modify websites, and allow transactability for
assigned seats for children 13 and under. These costs include startup implementation costs as
well as ongoing costs. Third parties involved in data exchange, such as global distribution
systems (GDSs) and direct-channel companies, would incur costs as well despite not being
directly regulated by the rule. Because these entities are already starting to upgrade systems for
market reasons, the cost properly associated with the proposed rule is the cost of requiring
them to upgrade earlier than they would without the rule.
Given the lack of current data, it is not possible to quantify benefits for consumers after
accounting for offsets. Potential benefits are from the reduction in deadweight loss due to
inaccurate price calculations and search costs. The potential for crowding out of relevant
information could offset these benefits. Because we cannot quantify benefits or disbenefits, it is
not possible to assess the net benefits at this time.

Appendix A International baggage fees by carrier
The Department collected baggage fee information for international flights on domestic carriers
with at least .05% of domestic passenger revenues. This appendix provides information on
baggage fees for individual carriers.
Alaska Airlines
International baggage fees were the same as those for domestic travel. Alaska noted via chat
that international taxes might result in a “nominal” increase to a baggage fee.
Allegiant Air
Allegiant does not offer international flights.
American Airlines
American’s fees vary by region and country, as well as by seasonal travel dates for destinations
in the Caribbean, Central America, and South America. Table 14 shows maximum fees based on
seasonal pricing.

Delta Air Lines
Delta provides a fee calculator rather than a table of fees on its website. The fees vary based on
the destination, the cabin class, and whether passengers own an affinity credit card. In general,
first and second bags are checked free for passengers in the Delta One, First, and Premium
Select fare classes. For the main cabin fare classes, baggage fees vary based on the destination
and credit card. For instance, on a trip to Buenos Aires, the first checked bag is free and the
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 34
second bag costs $60. On a trip to London or Tokyo, in contrast, the first checked bag is free,
and the second bag costs $100. On a trip to Rio De Janeiro, the first checked bag is $60 for Basic
but free for gold card holders.
Frontier Airlines
Frontier’s website requires the traveler to select the origin, destination, and dates of travel to
display the baggage fees; fees vary based on dates, routes, and purchase timing and channels. A
search for a one-way flight from Denver to San Jose, Costa Rico on June 18, 2022, returning June
23, 2022, yields the following fees:
For carry-on bag, the fee ranges from $60-$89
For the first checked bag, the fee ranges from $55-$89
For the second checked bag, the fee ranges from $60-$79
Hawaiian Airlines
Hawaiian does not charge fees for the first two checked bags.
JetBlue
JetBlue’s website presents two bag fee tables arranged by fare and region.
Fees for Latin America and Caribbean routes are the same as U.S. domestic routes and depend
on the fare type purchased:
The first checked bag is either included (free) or $35
The second checked bag is either included (free) or $45
Fees for travel between the U.S. and U.K. depend on fare type purchased:
The first checked bag is included (free) for all fare types except Blue Basic, which costs
$65
The second checked bag is either included (free) or $105
Southwest Airlines
Southwest does not charge any fee for the first two checked bags of international travel, as with
domestic travel.
Spirit Airlines
As with domestic travel, Spirit Airlines’ website requires the traveler to select dates of travel and
the origin and destination of travel to display the baggage fees, and notes that bag prices vary
based on dates of travel, route, and timing/channel of purchase (e.g., during online booking,
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 35
before online check-in, during online check-in, at airport / group desk / reservation center, or at
gate). For example, a search for a one-way flight from Baltimore to Medellin, Colombia on June
17, 2022, returning June 24, 2022, yields the following fees:
For carry-on bags, the fee ranges from $45 to $76
For the first checked bag, the fee ranges from $34 to $76
For the second checked bag, the fee ranges from $58 to $79
United Airlines
Like with domestic travel, United requires travelers to use the online baggage calculator to
determine first and second checked baggage service charges. Table 15 compiles maximum
baggage fees for various itineraries using the calculator.
Exemptions or savings may apply based on fare type, frequent flyer status, affinity card
membership, pre-payment, and subscription plans. For Basic Economy fares, the first checked
bag will usually incur a fee.

Appendix B Air fare and ancillary service bundles
The Department collected information on ancillary services offered as bundles on domestic
carriers with at least .05% of domestic passenger revenues. This appendix provides information
on bundles for individual carriers.
Alaska Airlines
Alaska does not brand any offering as a “bundle” but offers three fare types in the main cabin
with varying levels of ancillary services : premium class(economy cabin seating with more
pitch and other attributes), main cabin” (with no change fees and no charge for advance seat
assignments), and saver fares” (a basic economy offering, with most seats assigned only at
check-in, and no ticket changes or refunds).
Most customers seated in the main cabin pay $30 and $40 for first and second checked bags.
Waivers may apply for certain fares or frequent-flyer program members, and flights within
Alaska include two checked bags in the fare.
Allegiant Air
Allegiant offers separate (à la carte) pricing for most ancillary services but has introduced
bundles of ancillary services in its booking process. Allegiant advertises the bundles as ways to
streamline booking and save time and money.
Passengers may choose not to purchase bundles and instead buy seat assignments and
baggage separately. Fees for seat assignments vary by flight, and fees for carry-on and checked
bags range from $10 to $75 based on routing.
Changes to tickets may be allowed for a change fee and difference in fare. Customers may also
purchase “Trip Flex,” which allows a one-time change for no additional fee.
American Airlines
America takes a hybrid approach to bundling products and services. American offers “premium
economy,” “economy,” and “basic economyfare bundles in the main cabin. “Premium
economy” includes wider seats, food with free beverages, and free Internet access, among other
services. “Basic economy,” in contrast, has lower fares but does not allow for seat assignment
and is not eligible for ticket changes. The airline also allows passengers to purchase some
services separately, including checked bags, food, Internet access, and entertainment.
Delta Air Lines
Delta takes a hybrid approach to bundling products and services. It offers distinctly branded
bundles with varying levels of ancillary services, including Basic Economy” (the lowest cost and
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 37
with the most restrictions), “Main Cabin(standard economy), and higher-service classes (e.g.,
“Comfort+,”Premium Select,” “Delta One”). Delta also offers separate pricing for items such as
bags.
Basic Economytickets are non-changeable and non-refundable, although passengers may
cancel them for a fee to receive credit. The tickets also have restrictions on seat assignments,
earning miles, upgrades, and other aspects of air travel.
Passengers with “Main cabinand higher bundles can change their itineraries. Same-day
changes typically have a fee of $75, waived for certain frequent flyer program levels. Earlier
changes are often free for domestic flights but may have fees up to $500 internationally. Main
cabin customers may select seats in advance for free and can purchase optional fare upgrades
for premium seating. They may also buy certain main cabin seats in favorable locations.
All customers seated in the main cabin pay $30 and $40 for first and second checked bags.
Waivers may apply for elite frequent flyer program members.
Frontier Airlines
Frontier offers a selection of separately purchased products and services such as seats and bags.
It also advertises two options to “Bundle and Save”:
1. The “Works” bundle, only offered for sale at initial booking on its website, includes a
carry-on bag, a checked bag, seat selection and priority boarding, flight flexibility and
refundability. The bundle applies to all passengers in the same round-trip booking.
Pricing for this bundle appears on the carrier’s site during booking and starts at $59 for
one-way travel based on the route.
2. The “Perks” bundle, which can be purchased after a trip booking, does not have flight
flexibility or refundability; prices also rise before the departure date. The bundle applies
to all passengers in the same round-trip booking as well, and generally starts at lower
prices than the “Works” bundle.
Hawaiian Airlines
Hawaiian offers no bundles per se but offers several fare classes and opportunities for main
cabin consumers to add or upgrade separate products.Basic economyfares are non-
refundable, with no changes allowed. Passengers may select seats only upon check-in and may
not upgrade seats. “Main cabin” fares can be changed for free, although a fare difference may
apply, and passengers may select seats before check-in.
Most customers seated in the main cabin pay $30 and $40 for first and second checked bags.
Waivers may apply for certain fares or frequent-flyer program members, and up to two checked
bags on intra-island flights within Hawaii receive a $5 discount.
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 38
JetBlue Airways
JetBlue has adopted a hybrid approach to bundling, offering several fare bundles while still
charging separately for common items like bags and refreshments on board.
JetBlue’s basic bundle (Blue Basic) allows for flight changes and refunds for travel credit,
although passengers pay $100 to $200 depending on the route. The bundle also allows for
advance seat assignments for a fee ranging from $5-$40 up to 24 hours prior to departure, at
which point passengers may select seats for free.
Most of JetBlue’s non-basic fares act like fare bundles and include a carry-on bag, ticket
changes, seat selection, earlier boarding, and higher rates for earning reward points. Main cabin
customers may select seats in advance without a fee and can purchase optional fare upgrades to
premium seating. Most customers seated in the main cabin pay $35 and $45 for first and second
checked bags. Waivers may apply for certain fares or frequent-flyer program members.
Southwest Airlines
Southwest has an all-coach cabin with no reserved seating assignments. In addition, it has never
unbundled the two free standard bags and fee-free flight changes it offers in every fare. Instead,
Instead, Southwest offers increasing levels of services via distinctly branded bundles. These
bundles offer higher frequent flyer earning levels, transferrable flight credits, boarding priority
(which effectively grant increased access to seating choice and carry-on space), and
refundability, among other attributes.
Below are sample differences in fare product services using Southwest’s booking tool for a
roundtrip Dallas-Baltimore itinerary in June 2022.
$30 upgrade from “Wanna Get Away” to “Wanna Get Away Plus”: adds transferable flight
credits and same day flight changes and more points earning)
$50 upgrade from “Wanna Get Away Plus” to “Anytime”: adds refundability, boarding
priority and early check-in, and more points earning)
$40 upgrade from “Anytime” to “Business Select”: adds still earlier boarding and drinks on
board, and more points earning)
For an Orange County (CA)-Pittsburgh roundtrip itinerary in June 2022, the increments between
the different fare types are $30 (for “Wanna Get Away Plus”), $50-90 (for “Anytime” depending
on the departure and arrival times”), and $40 (for “Business Select”).
Spirit Airlines
Spirit advertises a “customizable” experience in which every attribute besides transportation
itself is charged separately, including bags, seat assignments, beverages, and boarding passes
Enhancing Transparency of Airline Ancillary Service Fees: Regulatory Impact Analysis 39
printed by an agent at the airport. Spirit lists at least 35 distinct fees apart from seat and bag
fees on its website fee reference page and does not appear to offer any form of bundling.
Spirit charges from $0 to $99 for modifying a ticket, depending on how far in advance of
departure the change is made.
Seating can be obtained at no additional charge for those consumers who wait for a randomly
assigned seat at check-in or boarding. Advance seat selection ranges from up to $50 for regular
seating and up to $250 for their larger seat product (“Big Front Seats”).
Spirit charges separately for carry-on bags and first and second checked bags, with prices that
vary by date and routing, and are charged per segment rather than one-way journey. These fees
also vary depending on the purchase channel and timing before departure and may be
discounted via purchased memberships. Although highly variable as described, these fees
appear to range from ~$30 to ~$84 on a selection of domestic itineraries.
United Airlines
United takes a hybrid approach to bundling products and services. It separates its basic
economyfare from other main cabin fares but also sells “United Travel Optionsbundles, which
allow a consumer to select from a menu of options at a lower cost than buying services
separately. These bundle options include upgraded seating. seat assignments, baggage, Internet
access, airport lounge access, and higher mileage earning. United also offers subscriptions of
varying lengths for items such as lounge access, Economy Plus seating, baggage, or Internet
access.
United’s basic economytickets cannot be changed or cancelled except under the
Department’s 24-hour rule, unless the passengers purchased one of the bundles. Seat
assignments are available upon check-in, or in advance for a fee starting at $9 one-way. “Basic
economy” passengers can bring a personal item on board but must check carry-on baggage.
Passengers with regular main-cabin tickets can change or cancel flights for free, with refunds
going to flight credit, although they incur a fee for changing a flight the same day if it does not
involve standby travel. They may select or change seats at or after booking for free, although
upgraded seats and seats in some locations may require a fee.
Most customers seated in the main cabin pay $35 and $45 for first and second checked bags.
Waivers may apply for certain fares or frequent-flyer program members.
