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