Scandinavian Airlines or SAS, previously Scandinavian Airlines System, is the flag carrier of Sweden, Norway and Denmark, and the largest airline in Scandinavia.
Part of the Scandinavian Airlines System Aktiebolag and headquartered at Stockholm-Arlanda Airport in Sigtuna, Sweden, the airline operates 182 aircraft to 90 destinations. The airline's main hub is at Copenhagen-Kastrup Airport, with connections to over 50 cities in Europe. Stockholm-Arlanda Airport (with more than 30 European connections) and Oslo Airport, Gardermoen are the other major hubs. Minor hubs also exist at Bergen Airport, Flesland, Gothenburg-Landvetter Airport, Stavanger Airport, Sola and Trondheim Airport, Værnes.
The airline was founded in 1946 as a consortium to pool the transatlantic operations of Svensk Interkontinental Lufttrafik, Det Norske Luftfartselskap and Det Danske Luftfartselskab. The consortium was extended to cover European and domestic cooperation two years later. In 1951, all the airlines were merged to create SAS.
SAS is one of the founding members of Star Alliance.
