American Airlines is preparing its Airbus A320-family pilots for flying transatlantic services with the Airbus A321XLR. Starting on September 4, the airline ran 42 roundtrip services between Philadelphia International Airport (PHL) and Edinburgh Airport (EDI) with Federal Aviation Administration (FAA) inspectors on board to certify the airline to conduct these kinds of operations in the North Atlantic. Training covered daily-shifting North Atlantic Tracks, non-radar Air Traffic Control (ATC) interactions, diversion planning, and satellite communication drills.
