 An agreement for the provision of subsidies on services to Oslo and Bergen was not reached with the Ministry of Transport until 1990 . The state agreed to provide NOK 4 @.@ 5 million , with the municipalities providing another NOK 2 @.@ 6 million , and Oppland County Municipality NOK 2 million . The county and municipalities were allowed to reduce their subsidies in the event that passenger numbers increased . Although initially planned to be introduced in January 1990 , Widerøe later dropped out , and the contract was awarded to Coast Air , who began operating on 3 September 1990 , using a de Havilland Canada Twin Otter aircraft . The deal was the most expensive subsidy for regional aviation in the country ; while the national average was NOK 156 , the Fagernes route cost the authorities NOK 2 @,@ 000 per passenger .
