 The late 1970s and early 1980s was a time of economic problems for airlines worldwide . Passenger numbers stabilized , and Braathens SAFE introduced a 15 % discount to <unk> of 100 tickets at one time . The company hit NOK 1 billion in revenue in 1981 . <unk> tickets were not sufficient to cover the increasing costs , particularly related to fuel , and the company introduced the internal campaign <unk> @-@ 82 . This involved a more market @-@ oriented management and a focus on service increase , including better <unk> and free coffee . During the summer , the reduced demand made the airline introduce discounted " summer tickets " for NOK 280 on any route in Southern Norway . This gave a 75 % load factor , the highest for the whole year .
