At the moment, 10+ pilots have transitioned over to UPS through the FlightPath programs. There are currently 45+ pilots in the program at AMF - about half are in FlightPath I and half in FlightPath II.
Have 3+ transitioning every quarter.
FlightPath I has you start as an intern at UPS (during or right after college / flight training), then go to AMF (usually starting in the right seat), then go back to UPS as a First Officer after completing the requirements.
FlightPath II has you joining the program once you become an AMF pilot, then transitioning to UPS as a First Officer after completing the requirements.
