Keflavík Airport (Icelandic:Keflavíkurflugvöllur[ˈcʰɛplaˌviːkʏrˌflʏɣˌvœtlʏr̥]) (IATA:KEF,ICAO:BIKF), also known asReykjavík–Keflavík Airport, is the largestairport inIceland and the country's mainhub for international transportation. The airport is located approximately 3 km (1.9 mi) west of the town ofKeflavík,Reykjanesbær[2] and 50 km (30 mi) southwest of the capitalReykjavík. The airport has two runways, each measuring approx. 3,050 m (10,010 ft).[5] Most international journeys to or from Iceland pass through this airport and it is the5th busiest airport in the Nordic countries.[6]
Keflavík is ahub forIcelandair and is served by 27 airlines as of 2025.[7][8] The airport is only used for international flights; all domestic flights use the smallerReykjavík Airport, which lies three kilometres (two miles) from Reykjavík's city centre. Keflavík Airport is operated byIsavia, a government enterprise.
Originally, the airport was built by theUnited States military during themilitary allied occupation of Iceland inWorld War II, as a replacement for a small British landing strip atGarður to the north. It consisted of two separate two-runway airfields, built simultaneously just 4 km apart.Patterson Field in the south-east opened in 1942 despite being partly incomplete. It was named after a young pilot who died in Iceland.Meeks Field to the north-west opened on 23 March 1943, where the airport is still located today. It was named after another young pilot, George Meeks, who died on theReykjavík airfield.Patterson Field was closed after the war, butMeeks Field and the adjoining structures were returned to Iceland's control and were renamedNaval Air Station Keflavik, named after the nearby town ofKeflavík.[9][10][11]
In 1949, a passenger terminal was built by theLockheed Overseas Aircraft Service. In its first years the passenger terminal was mostly used for troop transport as well as transatlantic technical stops; civilian airlinesIcelandair andLoftleiðir were still based at the smallerReykjavík Airport.[12][9]
In 1951, the U.S. military returned to the airport under a defence agreement between Iceland and the U.S. signed on 5 May 1951.[13]
The presence of foreign military forces in Iceland under theNATO-sponsored Iceland–U.S. Defense Agreement of 1951 was controversial in Iceland, which had no military forces other than theIcelandic Coast Guard.[14] During the 1960s and 1970s, rallies were held to protest the U.S. military presence in Iceland (and in particular at Keflavík), and every year protesters walked the 50-kilometre (30 mi) road from Reykjavík to Keflavík and chanted "Ísland úr NATO, herinn burt" (literally: Iceland out of NATO, the military away). The protests were not effective.[15]
Until the 1960s, the airlinesIcelandair andLoftleiðir Icelandic were solely based at the smaller civilianReykjavík Airport, which is situated within the city and did not have military access restrictions.[16]
Loftleiðir took delivery of its firstCanadair CL-44 aircraft in 1964 and Icelandair took delivery of aBoeing 727 as Iceland's first jet aircraft in 1967.[17][18] These new aircraft were considered too large for regular operation on the shorter runway at Reykjavík Airport. Both airlines began operations of their new larger aircraft from the longer runway at Keflavík Airport, greatly increasing the civilian passenger traffic through the Keflavík terminal.[18]
By the 1970s, almost all international traffic was moved to Keflavík, relegating Reykjavík Airport to serving domestic services and limited short-haul international traffic toGreenland and theFaroe Islands.[19] Theroad from Reykjavík to Keflavík was newly rebuilt and paved by 1965 which greatly improved access to Keflavík Airport from the city.[20]
The original Keflavík passenger terminal built in 1949 was located within theNASKEF military air base. Travellers therefore had to pass through military checkpoints to reach their flights.[9] The situation of having to pass through a U.S. military base in order to access the passenger terminal remained unchanged as civilian passenger numbers increased and was not considered ideal.
Subsequently, in April 1987 the Icelandic government finished construction of a relocated civilian terminal which was located on the north side of the airport. The new terminal had separate access from the military area and was accessible without passing through the military area. The new terminal was named afterLeif Erikson who was the first European to arrive in North America[21] (Flugstöð Leifs Eiríkssonar [is], "Leif Erikson Air Terminal").[22]
The two 3,000-metre-long (10,000 ft) and 60-metre-wide (200 ft) runways were large enough to supportNASA'sSpace Shuttle as well as theAntonov An-225. On 29 June 1999,Concorde G-BOAA flew fromHeathrow Airport to Reykjavík (Keflavik airport). The Concorde had been there earlier.[23] Due to its location, the airport is also an important diversion landing site for large aircraft in transatlanticETOPS operations.[24]
The terminal was extended with the opening of the South Building in 2001, to comply with the requirements of theSchengen Agreement. The North Building was enlarged and finished in 2007.[25]
The United States military base,NASKEF, closed down in 2006 and was handed over to the Icelandic Government.[26] The original Keflavík passenger terminal, built in 1949 and defunct since 1987, was demolished in 2018.[27]
The airport was used as a hub by defunct airlineWOW air (and earlier asIceland Express) until it ceased operations on 28 March 2019.[30] Similarly, it was the hub for the airlinePlay until they ceased operations on 29 September 2025 (2025-09-29)[31]
In September 2018,Atlantic Airways moved their operations fromReykjavík Airport to Keflavík Airport, as they transitioned to usingAirbus A320 aircraft which are too large for Reykjavík Airport, having previously usedAirbus A319 aircraft.[32][33] Similarly,Icelandair moved all of theirGreenland-bound flights from Reykjavík to Keflavík Airport in 2022, to allow easier onward connections.[34]
In 2012, 2016-2019 and 2023, Icelandair operated a domestic service toAkureyri Airport, only available for international connecting passengers.[35][36]
In 2016, the south terminal was expanded adding seven gates.[37] The ramp area to the east of the airport was expanded in 2018, adding 13 remote stands.[38] A new 1.2 km taxiway was constructed in 2023 byIsavia, which allows better aircraft traffic management at the airport.[39]
The airport's masterplan provides a phased approach to eventually accommodate 15 million passengers per year,[40] including a third runway, along with new terminal piers and anairport city.[41][42]
A major expansion of the new eastern wing was opened in 2023-2025, increasing the terminal's total area by 30%, including an expanded arrivals hall including a new baggage reclaim hall, retail facilities, four newjet-bridge gates, two new remote-stand bus gates and new spaces for retail units, including afood hall.[43][44]
As of 2024, a 1,900 square metre expansion of the south terminal is also under construction, on its east side.[45]
The airport has a single terminal, originally called Leifsstöð. (named after explorerLeif Erikson).[46] A total of 13 jet-bridge gates and 17 remote stands are available.[47] The terminal is split into A, C and D gates.A gates are located closest to the main lounge along the main hallway.C-gates are located past the main hallway on the upper level of the south building.D-gates are non-Schengen gates on the lower level of the south building.[25] Airside, pastairport security, one emerges into theSchengen side of the terminal. To access flights to non-Schengen countries (including theUK andUnited States), one must pass throughpassport control.[48][49]
Although the population of Iceland is only about 400,000, there are scheduled flights to and from numerous locations across North America and Europe. The largest carrier operating out of Keflavik isIcelandair. The airport only handles international flights; domestic flights are operated fromReykjavík's domestic airport.
The following airlines operate regular scheduled and charter services to and from Keflavík:[50]
The airport is located approximately 3 km (1.9 mi) west of the town ofKeflavík,Reykjanesbær. The airport is linked to downtownReykjavík via a 50-kilometre (30 mi) journey on theRoute 41dual carriageway. Long-term and short-term parking is available at the airport.[137] Taxis are available outside the terminal. Rental cars are available from various companies.[138]
There is a separated pedestrian and bike path from the airport to the town ofKeflavík, but not to Reykjavík.[2]
Public buses are operated byStrætó bs on route 55 to Mjódd bus station (located in Reykjavík's suburbs); the public bus stop is not located outside the airport terminal itself, but is located a few hundred metres away, near the car rental area.[139]
Private companies Flybus, Airport Express and others operate express services to downtown Reykjavík, including toReykjavík Airport (domestic) as well as stops and transfers to hotels.[140]
On 21 July 2013, a RussianSukhoi Superjet 100 airliner, prototype aircraft 97005, made abelly landing during a test flight. The cause was a crew mistake due to fatigue. They operated the plane manually in order to simulate failures.[141][142]
