What is the airline code for Swiss International Air Lines?
The IATA airline code for Swiss International Air Lines is LX, and its ICAO code is SWR. The two-character IATA code prefixes the carrier's flight numbers, for example LX123.
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 LX code comes from
LX carries one of aviation's more poignant code stories. It belonged to Crossair, the Swiss regional carrier, and when Swissair collapsed in 2002 the successor airline SWISS was built on Crossair's operating certificate. SWISS therefore flies under Crossair's old LX rather than Swissair's famous SR, which died with the company.
