 Both Braathens SAFE and SAS had been cross @-@ subsidizing their routes . Through the regulations , the airlines had agreed to fly to unprofitable airports , in exchange for making higher profits on other routes . With free competition , this would not be followed , and the authorities announced the introduction of public service obligations on routes that were not profitable . To finance these , a NOK 10 fee would be charged on all primary routes . The cost of collecting this fee was so high that SAS and Braathens SAFE announced it was cheaper to continue to fly to the unprofitable airports . Braathens SAFE stated that their routes Haugesund – Bergen and Oslo – Røros – Trondheim were not profitable .
