What is the traveler’s liability if a non-U.S.-certificated (foreign) air carrier is improperly used?
A10– There is no reimbursement (for any leg of the journey) for transportation cost when unauthorized/ unapproved non-U.S.-certificated air carrier service is used. If U.S.-certificated air carrier service is available for an entire trip and the traveler uses a non-U.S.-certificated air carrier for any part or the entire trip, the transportation cost on the non-U.S.-certificated air carrier is not payable. See JFTR, par. U3125-C5 & JTR, par. C2204-C5.
