Scandinavian Airlines-SAS has made this announcement:

SAS is introducing a total of four new return flights a week to and from Sälen/Trysil. The services from Denmark and the United Kingdom will operate during the winter season until Easter. With over 250 slopes at Skistar’s resorts within a 25-40 minute transfer from the airport, the new SAS services offer an entirely new way of getting to the Scandinavian ski resorts and mountain areas in Sälen and Trysil. SAS and SkiStar are also entering into a strategic partnership which will simplify the booking procedure for ski travel, for example.

The flying time from Copenhagen and Aalborg to Sälen/Trysil is about 1 hour and 20 minutes, while the flight from London takes about two hours. SAS will operate flights to Scandinavian Mountains Airport (SCR) starting on 29 December from Denmark and 28 December from the United Kingdom. The new services will be operated with the new SAS Airbus 320neo aircraft, which is the quietest and most fuel-efficient plane in the industry and reduces carbon emissions by up to 18 percent.
