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