On 25 June , Braathens SAFE applied to fly to London , but instead wanted to fly to London <unk> Airport , to have better landing slots . The concession was granted on 18 January 1991 , but the airline chose to not start the route . The company had been granted a concession to <unk> in Sweden , and the route opened on 2 May 1991 with two daily departures . This was later reduced to one . In October 1992 , the two airlines that flew from Oslo to Gatwick , Norway Airlines and Dan @-@ Air , filed for <unk> .
