What the codes mean

The two-character IATA code is the one on tickets, boarding passes and flight numbers (IF 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 IFL123 is called “INTERFLUG one two three”.
