Hi Everyone, If you will be flying internationally and want to charge your federal grant, please be sure to verify that all flights of your trip are a US carrier, or code-shared carrier. Please see the below Decision Tree and Fly America Exception Certification forms. Some of the more common allowable exceptions to the Fly America Act are: No U.S. flag air carrier provides service on a particular leg of the route Use of a U.S. flag air carrier increases the number of aircraft changes outside the U.S. by two or more Use of a U.S. flag air carrier extends travel time by six hours or more Use of a U.S. flag air carrier requires a connecting layover time of four hours or more at an overseas interchange point However, if you have booked an international flight because of any exceptions to the Fly America Act, please be sure to have proof from a travel agency website, Expedia, or some other site to show that taking a US Carrier would have extended your travel or layover time or required more than two aircraft changes. Doing this will help get your reimbursement processed faster. This is because OSP verifies the information on the Certification form and does so by using a system that checks the flights that were available during the time of the trip. I know this sounds strange, but the cost of the airline ticket is not an exception to the Fly America Act. https://osp.gmu.edu/wp-content/uploads/FAA-DecisionTree-072117.pdf https://osp.gmu.edu/wp-content/uploads/FLY-AMERICA-EXCEPTION-CERT-050217.pdf Thanks, Terri Terri Mancini, MPA Director, Sponsored Research Administration Volgenau School of Engineering George Mason University 4400 University Boulevard, MS 4A3 Fairfax, VA 22030 703-993-9550 PH 703-993-9641 FAX
