 Following the decision to sell the two 767s , management also decided to sell the four remaining F @-@ 28s . This would allow Braathens to operate a fleet of pure 737 @-@ 200 , giving lower operating costs . One 737 was taken out of service in 1984 , and the four F @-@ 28s sold in 1986 . The same year , seven more 737 @-@ 200s were delivered , along with two more in 1987 and 1988 . By then , Braathens <unk> entire fleet consisted of nineteen 737 @-@ 200s . At the same time , Boeing had launched the 737 @-@ 300 , a slightly larger aircraft with new <unk> @-@ 56 engines . Braathens SAFE considered the new aircraft , but where concerned that it used a traditional mechanical cockpit . The airline also needed larger aircraft for the charter traffic , and smaller aircraft for the domestic routes . The airline also considered the <unk> Douglas MD @-@ 80 and the Airbus A320 , but settled on the 737 following the announcement of the stretched 737 @-@ 400 , with 156 seats , and the shortened 737 @-@ 500 , with 124 seats . These had glass <unk> , and Braathens SAFE would be among the first airlines to receive both models . To finance the purchase , the airline sold all but two of the 737 @-@ 200s and leased them back . For some of the aircraft , they received more money than they had paid .
