Airlines / Singapore
SilkAir was an airline from Singapore that stopped flying in 2021. Its codes were MI (IATA) and SLK (ICAO), and its radio callsign was “SILKAIR”.
What the codes mean
The two-character IATA code is the one on tickets, boarding passes and flight numbers (MI 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 SLK123 is called “SILKAIR one two three”.
