Fly America Act

The Fly America Act is a federal regulation that states that any foreign air travel financed by federal funds must be booked through U.S. Flag Air Carriers, regardless of cost or convenience.

Because of the extra complications of foreign travel, you should use the PPPL contracted travel agency for all bookings except in extreme circumstances.

Use of U.S. Carriers - all commercial air travel between the United States and a foreign country and between foreign countries must be made via a U.S. flag carrier or U.S. code share. This applies to the following:

  1. Travel reimbursed from any funding source (DOE or non-DOE).
  2. International charter flights.
  3. Travel to/from Canada or Mexico.
  4. Flights to/from personal destinations in conjunction with official travel.


Use of Foreign Carriers - foreign carriers can be used only under the following circumstances:

  1. Non-Stop (no-aircraft change) - The use of a U.S. flag air carrier extends travel time, including delay at origin, by 24 hours or more.
  2. Connecting Flights - A U.S. flag air carrier must be used on every portion of the route where it provides service, unless, when compared to using a foreign air carrier, such use would:
    1. Increase the number of aircraft changes outside the United States by two or more.
    2. Extend travel time by six hours or more.
    3. Require a connecting time of four hours or more at an overseas interchange point.
