About the "FRONTIER-AIR" Callsign
When Frontier Flying Service pilots communicate with air traffic control, they identify themselves using the radio callsign "FRONTIER-AIR" followed by the flight number spoken in aviation pronunciation. For example, flight 456 would be "FRONTIER-AIR Four Five Six." Radio callsigns are assigned by ICAO and are distinct from the airline's marketing name.
