 On 2 April 2002 , SAS and Braathens split all the routes between them . SAS started flying on the main @-@ haul routes from Oslo to Trondheim , Bergen and Stavanger , with only a few flights to Stavanger flown by Braathens to get planes to the technical base there . From Oslo and Trondheim to Northern Norway , all routes were taken over by Braathens , with exception of a few flights made by SAS to Tromsø and Bodø . SAS also withdrew their flights from Oslo to Kristiansand and Ålesund , and Braathens increased their frequency on the route . Braathens retained the routes it had flown where SAS had not formerly flown . Braathens also kept the international flights to Barcelona , Nice , Malaga and Alicante . This reduced the overcapacity in the market , and allowed the SAS Group to save between NOK 600 and 900 million .
