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