In 1946, Braathens SAFE established their technical base at the airport, but left two years later.Gardermoen also became the reserve airport for Oslo Airport, Fornebu, when the latter was closed due to fog.The airport is located 19 nautical miles (35 km; 22 mi) northeast of Oslo, at Gardermoen in the municipality of Ullensaker, in Akershus county.It has two parallel roughly north–south runways measuring 3,600 metres (11,811 ft) and 2,950 metres (9,678 ft) and 71 aircraft stands, of which 50 have jet bridges.
However, the report did not look into the need of the Air Force that was stationed at Gardermoen, and was therefore rejected by the parliament the following year.
Some commercial traffic returned again in 1960, when SAS received its first Sud Aviation Caravelle jet aircraft, that could not use the runway at Fornebu until it was extended again in 1962.
SAS introduced a direct flight to New York in 1962, but it was quickly terminated.
A hub for Scandinavian Airlines, an operating base for Norwegian Air Shuttle, and a focus city for Widerøe, it connects to 31 domestic and about 128 international destinations.
Almost 26 million passengers traveled through the airport in 2016, making it the nineteenth-busiest airport in Europe.
