Scandinavian Airlines or SAS, previously Scandinavian Airlines System, is the flag carrier of Denmark, Norway and Sweden. Part of the SAS Group and headquartered in Stockholm, Sweden, the airline operates to almost 100 destinations. The airline’s main hub is Copenhagen Airport, which is the main European and intercontinental hub.
The airline was founded in 1946, when the flag carriers of Sweden, Denmark and Norway formed a partnership to handle the intercontinental air traffic of these three Scandinavian countries. SAS gradually acquired control of the domestic markets in all three countries by acquiring full or partial control of local airlines, including Braathens and Wideroe in Norway, Linjeflyg and Skyways Express in Sweden and Cimber Air in Denmark. In 1997 SAS formed the global Star Alliance network with Air Canada, Lufthansa, Thai Airways International and United Airlines.
