The first airline services to Kristiansund were part of the Bergen to Trondheim route which Norwegian Air Lines (DNL) established in 1935. These called at Ålesund, Molde and Kristiansund. The latter had its water aerodrome located at the port in the town center. The services were only flown during the winter. DNL resumed its routes in 1948, and Lufttransport commenced a service via Ålesund Airport, Sørneset to Oslo. From 1949 these were both taken over by West Norway Airlines, which lasted until the airline folded in 1957.
