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