Fly America Act & Open Skies Agreements Guidance
A person traveling on funds provided by the federal government must use a US flag carrier (an airline owned by an American company), regardless of cost or convenience.
When scheduling international travel that is federally funded, you must ensure that all flights, where possible, are scheduled on US flag carriers or on foreign air carriers that code share with a US flag carrier. Code sharing means: when two or more airlines “code” the same flight as if it was their own.
Travelers are encouraged to book their international travel, when federally funded, through Christopherson’s Travel Agency through State of Utah Travel. The agents are well versed in the Fly America Act. Please be sure to advise them that your trip is federally funded.
US Flag Air Carriers
In order for a flight to be in compliance with the Fly America Act, the code of a US 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. 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 or not the flight is on a US Flag air carrier.
US flag carriers and their codes are below to assist you.
- Airtran Airways (FL)
- Alaska Airlines (AS)
- American Airlines (AA)
- Continental Airlines (CO)
- Delta Airlines (DL)
- Frontier Airlines (F9)
- Hawaiian Airlines (HA)
- JetBlue Airways (B6)
- Midwest Express (YX)
- Southwest Airlines (WN)
- USAirways (US)
- Spirit Airlines (NK)
- United Airlines (UA)
Code Sharing
A US 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 US flag carrier. Compliance with the Fly America Act is satisfied when the US 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.

Exceptions to the Fly America Act
To document the exceptions, please complete and attach the Fly America Act Waiver Checklist.
The biggest exception to the Fly America Act is the Open Skies Agreement. On October 6, 2010, the United States and European Union (EU) Open Skies Air Transport Agreement was published by the US General Services Administration. This multilateral agreement is in place so that qualifying travelers, whose travel is supported by federal funds, may travel on EU airlines as well as US Flag Air Carriers. There are also Open Skies agreement with Australia, Switzerland, and Japan. Please see the Flowchart below.
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 – FTR sections 301-10.135-138. Please note that lower cost and personal convenience are not acceptable criteria for justifying the non-availability of a US–flag air carrier.
Please note: Travelers using Department of Defense (DOD), Air Force, Army, or Navy funds are not permitted to take advantage of Open Skies Agreements. These travelers must use an American carrier, unless they qualify for an exemption as noted in FTR 301-10.135, sections (a), (d), (e), (f), and (g).
