Essential Air Service (EAS): Frequently Asked Questions

Introduction
On February 14, 2012, President Obama signed into law a four-year reauthorization of Federal
Aviation Administration (FAA) programs, the FAA Modernization and Reform Act of 2012 (P.L.
112-95; hereinafter referred to as the 2012 FAA Reauthorization Act). The act is the first long-
term authorization for federal civil aviation programs since 2007, and was enacted following 23
short-term extensions.
The Essential Air Service (EAS) program was a focus of controversy during this legislative
process. The final legislation included policy reforms and changes to the funding of the EAS
program.
This report provides an overview of the EAS program and discusses the changes introduced by
the FAA reauthorization bill.1
What Is Essential Air Service?
The Airline Deregulation Act of 1978 (P.L. 95-504) gave airlines almost total freedom to
determine which domestic markets to serve and what airfares to charge. This raised the concern
that communities with relatively low passenger levels would lose service as carriers shifted their
operations to serve larger and often more-profitable markets.
To address this concern, Congress added Section 419 to the Federal Aviation Act,2 which
established the Essential Air Service (EAS) program to ensure that smaller communities could
retain a link to the national air transportation system. The purpose of the EAS program was to
provide a continuation of service to those small communities that were served by certificated air
carriers before deregulation, with subsidies if necessary. It continues to ensure at least a minimum
level of air service to small communities which would otherwise be unprofitable for commercial
airlines.
The EAS program is administered by the Department of Transportation (DOT),3 which
determines the minimum level of service required at each eligible community by specifying
• a hub through which the community is linked to the national network;
• a minimum number of round trips and available seats that must be provided to
that hub;
• certain characteristics of the aircraft to be used; and
• the maximum permissible number of intermediate stops to the hub.

U.S. Department of Transportation (DOT), Office of Aviation Analysis, http://ostpxweb.dot.gov/aviation/X-
50%20Role_files/essentialairservice.htm, as viewed on September 20, 2012.
2 Effective June 1994, the Federal Aviation Act was recodified as subtitles II, III, and V-X of 49 U.S.C.,
“Transportation.” The former Section 419 of the Federal Aviation Act is now 49 U.S.C. Sections 41731-41742.
3 The EAS program is administered by the Office of the Secretary of Transportation.

Essential Air Service (EAS): Frequently Asked Questions

Where necessary, DOT provides federal subsidies to a carrier to ensure that the specified level of
service is provided.
What Are the Eligibility Requirements?
The Airline Deregulation Act of 1978 made communities receiving scheduled air service from a
certificated carrier on October 24, 1978, eligible for EAS benefits. At that time, there were 746
eligible communities, including approximately 200 in Alaska.
Over the years, Congress and DOT have worked to streamline the program and make it more
efficient, mostly by eliminating subsidy support for communities within a reasonable driving
distance from a major hub airport. The 2012 FAA Reauthorization Act adopted additional EAS
reform measures, including Section 421, which amends the definition of an “EAS eligible place”4
to require a minimum number of daily enplanements.
Under the act, for locations to remain EAS-eligible they must have participated in the EAS
program at any time between September 30, 2010, and September 30, 2011. An EAS-eligible
place is now defined as a community that, during this period, either received EAS for which
compensation was paid under the EAS program or received from the incumbent carrier a 90-day
notice of intent to terminate EAS following which DOT required it to continue providing service
to the community (known as “holding in” the carrier). Starting October 1, 2012, no new
communities can enter the program should they lose their unsubsidized service.
This change limits EAS subsidies to those already receiving them and, in effect, eliminates the
eligibility of airports that were formerly eligible but did not receive subsidies at any time between
September 30, 2010, and September 30, 2011.
These EAS communities from FY2011 remain eligible for EAS subsidy if5
• they are located more than 70 miles from the nearest large or medium hub
airport;
• they require a rate of subsidy per passenger of $200 or less, unless the
community is more than 210 miles from the nearest hub airport;
• the average rate of subsidy per passenger is less than $1,000 during the most
recent fiscal year at the end of each EAS contract, regardless of the distance from
hub airport;
• the communities have an average of 10 or more enplanements per service day
during the most recent fiscal year beginning after September 30, 2012,6 unless
these locations are more than 175 driving miles from their nearest medium or

4 49 U.S.C. §41731.
5 The Department of Transportation Appropriations Act of 2000 (P.L. 106-69) Section 332 enacted the 70-mile rule and
the $200-per-passenger subsidy rule.
6 In effect, it would push the implementation of these criteria into FY2014.

large hub airport or if DOT is satisfied that any decline below 10 enplanements is
temporary.7
These limitations apply only to the contiguous 48 states and Puerto Rico. EAS communities in
Alaska and Hawaii are exempt from these requirements.
How Is EAS Funded?
The EAS program is funded through annual transfers of fees paid to FAA by foreign aircraft
overflying the United States, supplemented by annual appropriations of varying size. In FY2011,
the total EAS authorization was $200 million, including $50 million in annual mandatory funding
from FAA overflight fees, along with a discretionary appropriation of $150 million.
Section 428 of the FAA Modernization and Reform Act authorizes appropriation for the
discretionary portion of EAS funding of $143 million for FY2012, followed by gradually
decreasing annual funding over the next three years: $118 million for FY2013; $107 million for
FY2014; and $93 million for FY2015. However, it also authorizes all overflight fee revenues,
rather than just the $50 million provided historically, to be made immediately available to the
EAS program.
Consequently, while there seem to be annual reductions in spending levels for the program, these
discretionary funding cutbacks are expected to be matched by an increase in mandatory funds
generated by an increase in the revenues from overflight fees charged on foreign aircraft that fly
through U.S. airspace but do not land in the country. As a result, funding of the EAS program is
projected to remain at $193 million each year from FY2013 to FY2015 (see Table 1).

levels. This minimum-enplanement requirement could affect a small number of EAS communities, based on historical

Essential Air Service (EAS): Frequently Asked Questions

How Does DOT Select EAS Carriers?
DOT issues a request for proposals (RFP) to all scheduled carriers to provide service to an
eligible community and institutes a carrier selection proceeding using a bid system. However,
DOT does not automatically select the carrier submitting the lowest bid because DOT is required
by the governing statutes to use the following four criteria when selecting air carriers to serve
EAS communities:
• service reliability;
• contractual and marketing arrangements with a larger carrier at the hub;
• interline arrangements with a larger carrier at the hub; and
• community views.
The RFPs from DOT advise air carriers that their proposals for subsidy should be submitted on a
sealed bid, “best and final” basis, and set forth the level of service (frequency, aircraft size, and
hubs) that would be appropriate for the community given its location and traffic history. Once the
carrier proposals are received, DOT formally solicits the views of the communities as to which
carrier and option they prefer.
After receiving the communities’ input, DOT issues a decision designating the selected air carrier
and specifying the specific service pattern (routing, frequency, and type of aircraft), annual
subsidy rate, and effective period of the rate. DOT generally establishes a two-year EAS service
contract, which allows for the competitive bidding process and gives communities and DOT
flexibility to switch carriers.
What Is EAS Hold-In Authority?
If the last air carrier serving an EAS community wants to discontinue service, it must first file a
90-day notice of its intent to suspend service under the EAS statutes. Hold-in authority prevents
the incumbent carrier from suspending service until a replacement carrier begins service.
During the 90-day period, DOT will try to find a carrier willing to enter the market on a subsidy-
free basis. If unsuccessful, DOT issues an order prohibiting the suspension and requesting
proposals for replacement service, either with or without subsidy.
The incumbent carrier is eligible for compensation for being held in after the end of its original
90-day notice period, if it was serving a community subsidy-free. If the incumbent was already
serving a community with EAS subsidy, that carrier would continue to receive the same subsidy
rate for six months, at which time it is eligible for a rate increase.8

8 The six-month period discourages carriers from deliberately submitting below-cost proposals to get selected and
immediately coming back to DOT hoping to get a higher subsidy rate.

Essential Air Service (EAS): Frequently Asked Questions

How Many Communities Are Receiving
EAS Subsidies?

DOT currently subsidizes air service to serve more than 160 communities across the country that
otherwise would not receive any scheduled commercial air service. As of May 1, 2012, DOT was
subsidizing service at 120 communities in the contiguous 48 states, Hawaii, and Puerto Rico, and
43 communities in Alaska. In general, DOT subsidizes two to four round trips a day with small
aircraft from an EAS community to a major hub airport.
Table 2 provides a list of the subsidized EAS communities in the contiguous 48 states, Hawaii,
and Puerto Rico, together with their annual subsidy rates, as of October 1, 2012. Table 3 lists the
subsidized EAS communities in Alaska and their annual subsidy rates (as of October 1, 2012).
