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