Scandinavian Airlines (SAS), previously Scandinavian Airlines System, is the flag carrier of Denmark, Norway, and Sweden, and the largest airline in Scandinavia. The airline was founded in 1946 as a consortium to pool the transatlantic operations of Det Danske Luftfartselskab, Svensk Interkontinental Lufttrafik and Det Norske Luftfartselskap. The consortium was extended to cover European and domestic cooperation two years later. In 1951, all the airlines were merged to create SAS.
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 only intercontinental hub is at Copenhagen-Kastrup Airport. Copenhagen-Kastrup airport is also the largest of three hubs for European routes, with Stockholm-Arlanda Airport and Oslo International Airport as second and third respectively. Minor hubs also exist at Bergen-Flesland International Airport, Gothenburg-Landvetter Airport, Stavanger-Sola Airport and Trondheim-Værnes.
In 2012, SAS carried 25.9 million passengers, achieving revenues of SEK 36 billion. This makes it the ninth-largest airline in Europe. The SAS fleet consists of Airbus A319, A320, A321, A330 and A340, Boeing 737 Next Generation, and Bombardier CRJ900 aircraft.
