The Fly America Act requires all flights charged to federal awards be booked with U.S. flag air carriers, with certain exceptions (listed below). The requirement applies to all travelers, including a foreign visitor's flights when supported by federal funds. Specific guidelines and details are documented on the Airfare policy page.
Below is a list of major U.S. flag air carriers and their International Air Transport Association (IATA) airline codes. This information may change frequently, so a best practice is for travelers to check the airline's website to confirm that the airline is incorporated in the U.S.
| U.S. Airlines | Two-Letter IATA Code |
|---|---|
| Alaska Airlines | AS |
| Allegiant Air | G4 |
| American Airlines | AA |
| Delta Air Lines | DL |
| Frontier Airlines | F9 |
| Hawaiian Airlines | HA |
| JetBlue Airways | B6 |
| Southwest Airlines | WN |
| Spirit Airlines | NK |
| Sun Country Airlines | SY |
| United Airlines | UA |
Note: Air Canada is NOT a U.S. flag air carrier.
One exception to the Fly America Act is the Open Skies Agreement. The U.S. General Services Administration (GSA) states that qualifying travelers, whose travel is supported by federal funds may travel on certain foreign airlines as well as U.S. flag air carriers. The Open Skies Agreements exception does not apply if travel is funded by the Department of Defense (DOD) (which are Stanford Awards that are between TAAAA-TZZZZ) or by a department of the U.S. military. Specific guidelines and details are documented on the Airfare Policy page.
When air travel is paid for with federal funds, travel must either be on a U.S. carrier or, for specific destinations, may be in countries that have “Open Skies Agreements” with the U.S. government, such as countries in the European Union. (A list of current member countries of the EU is available at the Europa website).
For the most updated list of countries with Open Skies Agreements, visit the U.S. General Services Administration (GSA)’s Fly America Act webpage.

Click on a destination area for Open Skies Agreement specifics:
According to the Open Skies agreement between the U.S. and European Union (EU) countries, Norway or Iceland, travelers may fly on any EU airline when:
- Travel is NOT funded by U.S. Department of Defense (DOD) or the U.S. military, AND
- Flight touches down in an EU country, Norway or Iceland
When both conditions are met, travel should be booked on any of the U.S. flag airlines and European Open Skies airlines.
Note: When traveling to a destination serviced by an EU airline, Stanford travelers flying on sponsored funds can fly on either a U.S. carrier or an EU carrier as long as they touch down in an EU country. See the following examples of EU flights that are Open Skies compliant.
- Frankfurt (E.U.) –> San Francisco (U.S.)
- San Francisco (U.S.) –> Paris (EU)
- Dublin (EU) –> NYC (U.S.) –> Vancouver (Non-U.S./Non-EU country)
- Mexico City (Non-U.S./Non-EU country) –> NYC (U.S.) –> Madrid (EU)
- Cleveland (U.S.) –> Montreal (Non-U.S./Non-EU country) –> Barcelona (EU)
- Vienna (EU) –> Toronto (Non-U.S./Non-EU country) –> Denver (U.S.)
- Istanbul (Non-U.S./Non-EU country) –> Amsterdam (EU) –> Memphis (U.S.)
- Washington DC (U.S.) –> Sarajevo (ECAA - European Common Aviation Area)
- Belgrade (ECAA - European Common Aviation Area) –> Washington DC (U.S.)
According to the Open Skies agreements that the U.S. holds with Australia, Japan and Switzerland, travelers can use the respective country’s airlines or a U.S. flag carrier for travel to that country when:
- Travel is NOT funded by the U.S. Department of Defense or U.S. military
When conditions are met, travelers can use any of the U.S. flag airlines and applicable countries’ (Australian, Japanese, or Swiss depending on the destination of travel) Open Skies airlines.
- When travel is supported by federal funds, the traveler must fly on a U.S. flag airline unless it qualifies for an exemption as noted in the Fly America Act. Find the appropriate allowable exceptions on the Certification of Exception to Fly America Act.
In Summary: When traveling to the EU countries, Norway or Iceland, the traveler must land in a U.S., EU, Norway or Iceland destination, then any other city is allowed. However, an Australian carrier can only be used if the trip is directly to Australia. The same applies to Japanese and Swiss carriers.
