SAS Group has sold seven Bombardier Q400 turboprops to Norwegian operation Wideroe, following its divestment of a majority shareholding in the airline.
It says the loans on these aircraft have also been transferred to the carrier.
Three Q400s were also sold to Wideroe and then sold on to a leasing company.
Investors led by the Torghatten firm are taking an 80% share in Wideroe and SAS will hand over full ownership of the airline in 2016.
SAS Group says it will receive some SKr2 billion ($300 million) through the sale of the initial Wideroe shareholding and the aircraft, from which the group's liquidity will benefit by SKr1 billion.
