What is the airline code for Brussels Airlines?
The IATA airline code for Brussels Airlines is SN, and its ICAO code is DAT. The two-character IATA code prefixes the carrier's flight numbers, for example SN123.
IATA airline codes are two characters and can reuse letters over time, so a retired airline's code may later be assigned to another carrier. ICAO codes are three letters and are more stable, which is why flight plans use them.
Where the SN code comes from
SN is inherited from Sabena, Belgium's flag carrier from 1923 until its 2001 bankruptcy. The successor, SN Brussels Airlines, took the code and even worked it into its name before becoming Brussels Airlines. The code is now one of the clearest cases of an identifier outliving the airline it abbreviated.
