Oslo Gardermoen Airport

Updated: October 2026 – When people think of Norway, they think of fjords and mountains. For spotters, an airport on a wide, forested plateau north of the capital comes first. Oslo Gardermoen Airport is the hub of a country where the airplane is the normal means of transport for many routes. Domestic traffic is accordingly dense and the mix of jets, turboprops and long-haul accordingly colorful. On top of that comes something you rarely find at major European airports: the operator itself describes where you may stand as a spotter. This page shows you how Gardermoen works and how to plan your visit.

From drill ground to capital airport

Long before the civil airport, Gardermoen was a military place. The army drilled here as early as 1740, and in 1912 the first aircraft landed on the plain. The site was properly built up during the German occupation: the German Luftwaffe expanded it into a real airfield for the first time. After the war the Royal Norwegian Air Force took over, and Gardermoen remained one of its most important bases for decades.

Civil capital traffic back then ran through Fornebu, an airport on a peninsula right on the Oslofjord. Between 1946 and 1952 Gardermoen already had to step in once: because Fornebu was not equipped for it, the military field handled the capital’s intercontinental traffic. In the long run Fornebu was too small and too tightly surrounded by city. In 1992 the Norwegian parliament decided on Gardermoen as the new capital airport, and construction began in 1994.

On October 8, 1998, the new airport entered service, and Fornebu closed the same day. With the move the IATA code also changed: GEN became OSL. From the start the package included a dedicated high-speed rail line and new road connections. According to the Norwegian Wikipedia, the total investment including rail and road was around 22 billion kroner.

The airport is operated by Oslo lufthavn AS, a subsidiary of the state airport group Avinor. Avinor operates most of Norway’s commercial airports and reports to the Ministry of Transport. Militarily Gardermoen is still active today: the Air Force maintains an air station with transport aircraft in the northwest of the grounds.

Two runways, one terminal in between

The layout of Gardermoen is quickly explained. Two parallel runways run from south to north: in the west the 01L/19R at 3,600 meters, in the east the 01R/19L at 2,950 meters, both 45 meters wide. Between them lies the terminal with the aprons; according to Wikipedia, the system handles around 80 aircraft movements per hour. The instrument landing system is designed up to Category IIIa – important in a country where fog, snow and low clouds are part of everyday life.

With a north wind, takeoffs and landings are toward the north, that is on 01L and 01R. The approaches then come in from the south. If the wind turns south, operations run on 19L and 19R, and the landings come from the north over the forests. According to spotter guides, both runways are often used simultaneously for takeoffs and landings. Which runway a flight gets often depends on which pier it parks at.

Which direction is currently active, you can see in any flight tracker: if the approaches line up south of the airport, operations are on 01. If they come from the north, 19 is active. How to use ADS-B data for this is explained in the article Flight tracking with ADS-B. The basics of wind and runway choice are in Understanding runway direction at airports. What the numbers and letters mean is shown in the article Runway designations explained.

One terminal, several piers

Unlike many major airports, Gardermoen has a single, continuous terminal. It was built by the architects’ consortium Aviaplan, and plenty of wood and large glass surfaces still shape its look. In the 2010s the building was substantially expanded: in 2017 the new North Pier with eleven gates opened. Today the terminal covers around 265,000 square meters.

The South Pier had already been added in 2012, and in summer 2022 the expanded East Pier for non-Schengen traffic followed. According to spotter guides, traffic is divided roughly by area: domestic flights in one part, international Schengen and non-Schengen flights in the other. For you as a passenger that means: depending on the gate, you see very different parts of the apron.

The energy concept is remarkable. According to Wikipedia, the North Pier was the first terminal to receive the BREEAM “Excellent” sustainability rating. Snow cleared in winter is stored and used for cooling in summer. To our knowledge, a public observation deck is not part of the terminal.

SAS, Norwegian and Widerøe

Oslo is one of SAS’s three Scandinavian hubs – alongside Copenhagen and Stockholm Arlanda. At the fence you see SAS mainly with A320 family jets such as the Airbus A320neo. On long-haul, SAS connects Oslo, according to Wikipedia, with Newark, among others; which type flies there changes with the schedule. Typical for SAS long-haul is the Airbus A350-900.

Since September 1, 2024, SAS no longer belongs to the Star Alliance but to SkyTeam. The trigger was the entry of Air France-KLM during the restructuring. How the alliances differ is shown in the overview Star Alliance, oneworld and SkyTeam.

The second big name is Norwegian. The airline has one of its most important bases in Oslo and flies an all-Boeing fleet, so you often see the Boeing 737-800 and the 737 MAX 8. The third home carrier is Widerøe, Scandinavia’s big regional airline. Its turboprops such as the Dash 8-400 and regional jets such as the Embraer E190-E2 connect Oslo with smaller towns across the country.

Exciting for collectors: Norway’s country prefix is LN-. At SAS, though, aircraft with Swedish SE- and Danish OY- registrations also fly in Oslo. What is behind the prefixes is explained in the article Aircraft country prefixes.

Who else lands at Gardermoen

Norway’s geography produces domestic traffic you don’t know in Germany. Among the strongest routes, according to Wikipedia, are Trondheim, Bergen, Stavanger, Tromsø and Bodø – for many of these connections there is no fast alternative by rail. Narrowbody jets accordingly take off and land frequently with short turnarounds.

In European traffic in 2023, according to Wikipedia, Copenhagen, Stockholm, Amsterdam, London Heathrow and Paris-Charles de Gaulle were the most important destinations. The big network airlines fly to their hubs, including Lufthansa from Frankfurt and Munich, KLM from Amsterdam, British Airways, Air France, Finnair and Icelandair.

On long-haul, Wikipedia names connections by Qatar Airways to Doha, Emirates to Dubai and flights by Ethiopian Airlines, Thai Airways and Hainan Airlines. The Norway-based Norse Atlantic Airways has a base in Oslo and flies widebody jets like the Boeing 787-9, seasonally to Thailand, among others. Which type is flying which route today changes with the schedule – check shortly beforehand.

Cargo comes in the bellies of passenger aircraft and with dedicated freighters. Wikipedia lists, among others, Qatar Airways Cargo, Turkish Cargo, Ethiopian Cargo, Korean Air Cargo and Martinair. How to tell freighters apart is shown in the article Recognizing cargo aircraft.

Hercules and aviation history on the west edge

Gardermoen is still a military airfield today. The Air Force’s 335 Squadron has flown the C-130J Super Hercules from here since 2008. The transport aircraft are based in the northwest of the grounds and use the same runways as civil traffic. When a Hercules takes off on the west runway, it is the highlight of the day for many visitors. Special rules apply to photographing military facilities – the article Photographing a military airfield summarizes them.

On the west edge of the airport also lies Forsvarets flysamling Gardermoen, the aviation museum of the Norwegian armed forces. The collection moved into its present building in May 2000 and is now part of the armed forces’ museums. Among the best-known aircraft in the collection are a Northrop N-3PB, a Heinkel He 111 and a Junkers Ju 52. It is best to check opening hours with the museum in advance. Behind the museum building lies one of the official spotter places – more on that in a moment.

The official spotter places of Avinor

There is no observation deck like in Munich in Oslo. Instead, Avinor does something you don’t find at many major airports: on its website the operator itself describes where spotters can stand. The most important places at a glance:

• Forest edge by the west runway: Avinor itself calls this place at the edge of the forest next to 01L/19R the best. From here you overlook a large part of the airport. It is best in summer from about 1:30 p.m. until dusk. The nearest bus stop is called Kneppefeltet according to Avinor.
• East runway at 19L: On the east side, reachable via Jessheim and the Blikkvegen, there is an earth mound with a view over the runway. Here you have the best light in the morning until about noon.
• Hill at the air force museum (01L): A small hill behind the museum, with a bench and table, good for the afternoon into the evening. Bus stop according to Avinor: Lilleplassen.
• Wood chip piles at 01R: For landings from the south on 01R, this place at the fence is worthwhile from noon into the evening.

Avinor ties use to clear rules: consideration for flight operations, take your trash with you, no fire and no grill, at least three meters of distance from the fence when parking, and report anything suspicious to the airport. The areas are under video surveillance. Spotter guides name further points around the airfield, for example on the approach to 01R or in the forest at 19R. Some are at rental car areas or reserved for hotel guests – stay on public paths.

If you prefer to stay close to the terminal, spotter guides name an upper deck in parking garage P10 with a view of stands and taxiway. The view there is limited by barriers, and it gets crowded at peak travel times. For all places, expect access and rules to change – check Avinor’s current page before your visit.

Spotting in summer and winter

Spotter guides recommend the months from April to September for Oslo. Then the paths to the places are clear, and in midsummer the long evenings give you light until late. In winter things look different: snow, ice and cold make some field paths impassable, and the remote places have no shelter at all.

Winter has its charm too, though. De-icing, snow clearing and aircraft in front of snowy forest make pictures you rarely get in Central Europe. With warm clothing, spare batteries and a place within reach of the car, that works too. You will find tips in the article Plane spotting in winter, and for dull days in the guide Plane spotting in bad weather.

Getting there: Flytoget and Gardermobanen

Gardermoen is one of the best rail-connected airports in Europe. The purpose-built Gardermobanen leads from Oslo Central Station to under the terminal. The airport express Flytoget takes about 20 minutes for the route and runs at a dense frequency during the day; some of the trains continue beyond Oslo to Drammen. Regional trains and long-distance trains are added, among others toward Trondheim. According to Wikipedia, almost 70 percent of passengers use public transport.

By car you reach the airport via the E6 and the E16. For the spotter places at the fence, a car is much more convenient because the distances between the east and west side are long. Without a car you take regional buses to the stops that Avinor names for the individual places.

Oslo in a Nordic comparison

In northern Europe there are four big hubs, and each has its own character. Copenhagen is the largest of them and has a cult place at the fence with the Flyvergrillen. Stockholm Arlanda is the Swedish SAS hub, Helsinki the home of Finnair with a focus on Asia. Oslo scores with the densest domestic traffic, Widerøe’s turboprops and the officially described spotter places.

In principle, Gardermoen resembles Munich: two parallel runways far outside the city, the terminal in between and a fast rail link to downtown. The visitors’ hill with its beer garden is replaced in Oslo by the forest edge. You will find more destinations in the overview The best spotting spots in Europe.

Conclusion

Oslo Gardermoen Airport combines a long military history with a modern hub for all of Norway. Two parallel runways, a terminal with a station underneath and a traffic mix from SAS and Norwegian via Widerøe turboprops to the Hercules make it a worthwhile destination in the north.

There is no observation deck, but the operator itself describes where you may stand. Whoever checks runway direction and light beforehand, goes in summer and follows Avinor’s rules goes home with a logbook full of LN registrations.
