The Fly America Act (41 CFR 301-10.131 through 301-10.143) requires that all federally funded air travel be on a US flag carrier or US flag carrier service provided under a code share agreement.
US Flag Air Carrier
In order for a flight to be in compliance with the Fly America Act, the code of a
U.S. flag air carrier must be noted as part of the flight number on the airline ticket,
flight coupon (boarding pass), or passenger receipt. Each airline has a two letter
alpha code. U.S. flag carriers and their codes are listed below to assist you. From
this list, you will be able to compare airline codes on the ticket with those on the
list and thereby be able to ascertain whether the flight is on a US Flag air carrier.
U.S. flag air carriers:
• Airtran Airways (FL) • Alaska Airlines (AS) • American Airlines (AA)
• Delta Airlines (DL) • Frontier Airlines (F9) • Hawaiian Airlines (HA)
• JetBlue Airlines (B6) • Midwest Express (YX) • Southwest Airlines (WN)
• Spirit Airlines (NK) • United Airlines (UA) • USAirways (US)
• Virgin America (VX)
Code Share Agreements
Code sharing occurs when two or more airlines "code" the same flight as if it was
their own. In other words, a U.S. airline may sell a seat on the plane of a foreign
air carrier; this seat is considered the same as one on a plane operated by a U.S.
flag carrier. Compliance with the Fly America Act is satisfied when the U.S. flag
air carrier's designator code is present in the area next to the flight numbers on
the airline ticket, boarding pass, or on the documentation for an electronic ticket
(passenger receipt). See example below, where Delta Airlines (DL) has a code share
agreement with Air France (AF) to Paris, France.
Open Skies Agreements
The biggest exception to the Fly America Act are the Open Skies Agreements. The United
States and European Union (EU) "Open Skies" Air Transport Agreement was published
by the U.S. General Services Administration, providing full explanation of the multilateral
agreement in place so that qualifying travelers, whose travel is supported by federal
funds, may travel on European Union airlines as well as U.S. flag air carriers. These
agreements with other nations allow travel on foreign airlines under certain conditions
when procuring using federal funds.
Information about the four Open Skies Agreements along with a list of participating
countries is available on the GSA website.

City Pair Contracts
City pair contracts can be searched on the GSA website.
There are other exceptions to the Fly America Act, which may be appropriate as well. A list of exception criteria may be found in the Federal Travel Regulation Guidelines, sections 301‐ 10.135–138. Please note that lower cost and personal convenience are not acceptable criteria for justifying the non‐availability of a U.S. flag air carrier.
If flying under an exception to the Fly America Act, travelers will need to complete a Fly America Act Exceptions Form. This form should be submitted along with the Travel Budget Authorization and Travel Voucher when seeking reimbursement.
In order to qualify for an exception, you must answer the following:
§301-10.136 What exceptions to the Fly America Act requirements apply when I travel
between the United States and another country?
The exceptions are:
a. If a U.S. flag air carrier offers nonstop or direct service (no aircraft change)
from your origin to your destination, you must use the U.S. flag air carrier service
unless such use would extend your travel time, including delay at origin, by 24 hours
or more.
b. If a U.S. flag air carrier does not offer nonstop or direct service (no aircraft
change) between your origin and your destination, you must use a U.S. flag air carrier
on every portion of the route where it provides service unless, when compared to using
a foreign air carrier, such use would:
§301-10.137 What exceptions to the Fly America Act requirements apply when I travel
solely outside the United States, and a U.S. flag air carrier provides service between
my origin and my destination?
You must always use a U.S. flag carrier for such travel, unless, when compared to
using a foreign air carrier, such use would:
a. Increase the number of aircraft changes you must make en-route by 2 or more;
or
b. Extend your travel time by 6 hours or more; or
c. Require a connecting time of 4 hours or more at an overseas interchange point.
§301-10.138 In what circumstances is foreign air carrier service deemed a matter of necessity?
a. Foreign air carrier service is deemed a necessity when service by a U.S. flag air carrier is available, but
b. Necessity includes, but is not limited to, the following circumstances:
