What the codes mean
The two-character IATA code is the one on tickets, boarding passes and flight numbers (SQ 123). The three-letter ICAO code is used in flight plans and by air traffic control. The radio callsign is what pilots and controllers say on the radio: a flight filed as SIA123 is called “SINGAPORE one two three”.
