It is the owner of the airlines Scandinavian Airlines and SAS Connect. SAS once owned 19.9% of the now defunct Spanish airline Spanair as well as shares in Estonian Air and Skyways Express. SAS Group is partially owned by the governments of Sweden and Denmark with a 14.82% and 14.24% holding, respectively. The remaining 70.92% is held by private shareholders, of which Foundation Asset Management owns 6.50%.

The conglomerate was founded in 1951 as a merger between the three Scandinavian flag carriers Aerotransport, Det Danske Luftfartselskab, and Det Norske Luftfartselskap, after the three had been cooperating on international routes since 1946. Until 2001, the three national companies owned a fixed share of the SAS Group, after which the shares of the three companies were merged. Wikipedia
