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