Airport Administration

Oslo Lufthavn AS (OSL) was established on 13 November 1992, a month after the Norwegian Parliament decided to build the new Oslo airport. OSL is a wholly-owned subsidiary of Avinor AS, the former Norwegian Air Traffic and Airport Management (NATAM).

OSL was in charge of the planning and construction, and own and operate the new main airport at Gardermoen, 47 km north of Oslo. On 1 January 1997, OSL took on responsibility for the operation of the existing Oslo airports at Fornebu and at Gardermoen.

The establishment of OSL as a public limited company was a requirement of the Government's proposal to the Norwegian Parliament. OSL was financed by state loan and the sale of Fornebu airport. When the airport was completed in 1998, the loans was repaid by aviation charges and commercial income generated from its operation. Total investment was NOK 11.4 billion (based on 1992 conversion rates), including acquisition of land and compensation.
