The project was estimated to cost 267 million Norwegian krone. Estimates show that the benefit for society would be lower than the investment costs (a negative net present value), giving an average estimated NOK 124 million deficit. Norwegian Air Shuttle is building a unified fleet of 737-800 aircraft and will only be able to serve the airport during winter if the investments are carried out. The extension would allow increased charter traffic to Central Europe and increased regularity with existing flights. Avinor has stated that it cannot finance the investments without direct subsidies from the state.
