Oslo Airport, Fornebu (IATA: FBU, ICAO: ENFB) (Norwegian: "Oslo lufthavn, Fornebu" ) was the main airport serving Oslo and Eastern Norway from 1 June 1939 to 7 October 1998.
 It was then replaced by Oslo Airport, Gardermoen and the area has since been redeveloped.
 The airport was located at Fornebu in Bærum, 8 km from the city center.
 Fornebu had two runways, one 2370 m 06/24 and one 1800 m 01/19, and a capacity of 20 aircraft.
 In 1996, the airport had 170,823 aircraft movements and 10,072,054 passengers.
 The airport served as a hub for Scandinavian Airlines System (SAS), Braathens SAFE and Widerøe.
 In 1996, they and 21 other airlines served 28 international destinations.
 Due to limited terminal and runway capacity, intercontinental and charter airlines used Gardermoen.
 The Royal Norwegian Air Force retained offices at Fornebu.

Braathens South American & Far East Airtransport A/S or Braathens SAFE was founded by ship-owner Ludvig G. Braathen in 1946.
 It started as a charter airline based at Oslo Airport, Gardermoen in Norway, flying to destinations in the Far East and in South America.
 At first the airline used Douglas DC-4s, and later also Douglas DC-3s.
 In 1948, the airline moved to Oslo Airport, Fornebu and started regular scheduled flights to the Far East.
 In 1952, the airline started cooperation with the Icelandic airline Loftleidir, where until 1960 the two airlines in cooperation flew flights to Reykjavík.
 Domestic services started in 1951, using de Havilland Herons on a route from Oslo to Stavanger via Tønsberg.
 Braathens SAFE also established at Stavanger Airport, Sola.
 A second route was started two years later to Trondheim.
 The Heron routes also stopped in Farsund, Kristiansand, Notodden to Stavanger and Hamar, Røros to Trondheim.
The location of the main airport serving the city of Oslo, Norway, has been the subject of several political debates since 1918.
 The first controversy was initially related to choice between the islands of Gressholmen and Lindøya in the Oslofjord for a water aerodrome.
 The debate later changed, arriving at the decision in 1933, to locate a new airport at Fornebu.
 However, Oslo Airport, Fornebu, being located on a peninsula, proved to not have sufficient space for a runway capable of intercontinental aircraft and a second runway, resulting in plans from the 1960s to replace it.
 The main contestants were Gardermoen Air Station, Hurum, Hobøl, Ås and a split solution between Fornebu and Gardermoen.
 In 1992, parliament decided to build an all-new Oslo Airport, Gardermoen; when it opened in 1998, Fornebu was closed.
 The decision caused the southern parts of Eastern Norway to be moved further from the main airport, and the regional, privately owned Sandefjord Airport, Torp became the base for low-cost airlines. Moss Airport, Rygge opened in 2007, becoming the third simultaneous airport to serve Oslo, and closed in 2016.
