Are there special considerations when flying internationally for sponsored travel?

Yes. The Fly America Act, enacted in 1974, mandates the use of U.S. flag air carriers for federally funded international travel. If you are scheduling international travel that is funded by a federal grant, you must ensure that all flights (where possible), are scheduled on U.S. flag air carriers or on foreign air carriers that code share with a U.S. flag air carrier.  See Office of Sponsored Programs website for more information.
