Regarding the Fly America Act (49 U.S.C. 40118), a person traveling on funds provided by the U.S. Federal Government must use a U.S. flag carrier (an airline owned by an American company), regardless of cost or convenience. A person may travel on a foreign air carrier that shared a code with a U.S. flag carrier. There are several exceptions that can be approved with a waiver. Kindly see the attached documents that will help you determine when and if a waiver is needed for travel and a sample draft of the Fly America Certification Waiver. Waivers are required for international flights, but are not required for any domestic flights. Unfortunately, you must submit a waiver each time it is required before the purchase of the international flight, as there is no ‘blanket’ waiver that covers all the flights in the project. When planning a trip, please keep the waiver process in mind for timing.
