SAS Braathens was the name of Norway's largest airline, created by a merger between Scandinavian Airlines' Norwegian division and Braathens in 2004. On 1 June 2007, the airline was integrated into mainline SAS, and changed its name to SAS Scandinavian Airlines Norge. The airline operated from its hub at Oslo Airport, Gardermoen, and was also the largest national branch of Scandinavian Airlines. SAS Braathens had its head office in Diamanten on the grounds of the now-closed Fornebu Airport in Fornebu, Bærum, Norway.

Braathens ASA, until 1997 Braathens South American & Far East Airtransport A/S and trading as Braathens SAFE, was a Norwegian airline which operated from 1946 until it merged with Scandinavian Airlines (SAS) in 2004 to become SAS Braathens. For most of its history, Braathens was the largest domestic airline in Norway, but did not operate an international network for many years. Its main hubs were Oslo Airport, Fornebu and later Oslo Airport, Gardermoen, and briefly Stockholm-Arlanda Airport. The airline operated 118 aircraft of 15 models, mostly Boeing 737 variants. Braathens served 53 airports and 50 cities with scheduled services through its history.
