While it was a rather sleepy airport until the 2000s, this airport has become a rapidly growing hub for transatlantic flights, especially for discount travellers and smaller cities. The banking crisis in Iceland after 2008 led to exchange rates favorable to tourism, and developments in aviation allowed transatlantic flights on narrowbody twin jet planes with a stop in KEF. The main Icelandic airline, Icelandair (and, until March 2019, the ill-fated WOW air) have continually used the central location in the Atlantic for destination networks on both sides of the pond, but European carriers now also link KEF to their bases on the continent, and even North American carriers have started mostly seasonal flights.
This rapid growth means that the terminal is stretched way beyond its capacity. The airport is being expanded, but expect crowded gates and nowhere to sit. Especially since the double digits growth means one expansion is usually done two years after the next would have become necessary.
While the airport is often marketed as "Reykjavík" (no doubt in part because nobody outside of Iceland knows any other town in the country) it is actually some 50 km (31 mi) from the town and Reykjavík actually has its own airport that sees domestic flights and flights to the Faroes or Greenland. To avoid confusion, it might help to use the IATA code KEF when referring to the airport.
While this split of domestic and international airport might seem awkward and indeed is a problem for Icelanders arriving home from vacation, it gives you a good opportunity to check out the capital region before heading out on a domestic flight.
Naturally, Icelandair offers the most connections at this airport. However, there is a good selection of European and U.S. carriers that have flights to their hubs and others you might not even think of.
Icelandair pioneered the "Iceland layover vacation" concept and advertises a stay at KEF on transatlantic routes as a feature rather than a bug.

Transport between the airport and Reykjavik, 50 kilometres (31 mi) away, is by the fast Route 41.
The buses have a timetable adapted to the flight schedule. They go to and from the Reykjavik bus terminal, taking around 45 minutes. To get to the domestic airport a bus change is needed at the bus terminal.
Buses to Reykjavík are operated by Airport Express, Flybus, and Strætó bs. Some buses will come 30–45 minutes after the arrival of any flight. This includes delayed flights and flights in the middle of the night. While you won't have to pre-book the Stræto bus, it comes highly recommended to pre-book if you want to go with one of the other companies. As Stræto does not run at all times, you should check schedules before deciding on an option. See also Airport Shuttle. There is also a bus to Keflavík.
- Flybus. offers regular service to either the BSI bus terminal, just south of the city centre (45 minutes), or directly to Reykjavik hotels with advance notice to the driver (3000 kr one-way or 5500 kr round-trip). Buses leave the airport as early as 03:30. Tickets can be bought either at the airport or online. Due to the Covid 19 Pandemic Flybus ceased all service at the end of March 2020 until further notice. 2500 kr one-way or 4500 kr round trip.

Taxis are available outside the terminal. They cost 14,000 kr for 1–4 passengers and 19,000 kr for 5–8 passengers. Taxi drivers are generally honest and won't overcharge tourists.
There are dozens of car rental agencies operating, including Avis, Hertz, Budget and Europcar. On some roads, especially in the Interior of Iceland, only 4x4 vehicles are permitted by law (and some roads require a real off-road vehicle). These include highways designated with the letter F.
A pamphlet about this and rules of the Icelandic roads, provided by the government, will usually be given out whenever you rent a specific type of car.
There are no railways in Iceland.
The first railway in Iceland, 49 km long, is planned to link the airport to Reykjavik in order to relieve one of the country's busiest roads. The railway will accommodate high-speed trains of up to 250 km/h, which will enable the distance to be travelled within just 18 minutes. As of 2016, construction was to begin in 2020.
- Icelandair Saga Lounge. Even if you don't qualify for free lounge access, this is one of the more pleasant ways to spend a layover long enough to require killing time but too short - or too late at night - to take the bus to Reykjavik
Eat and drinkEdit
The duty free shop is one of the cheapest places in Iceland to buy alcohol which is why many locals grab a beer or two before heading out. There are also all manner of Icelandic or international foods on sale. Nothing in Iceland is cheap compared to most of the rest of the world and the airport is naturally no exception. Still, fish is caught locally and thus less expensive, relatively speaking, and often excellent.
An ATM is available in the baggage claim area for you to take out króna.
There's free and unlimited WiFi.
Sleeping overnight in the airport is forbidden (no doubt all those late night departures and the crowded nature of the place) and there is no hotel on the grounds of the airport. However, there is a selection of hotels in nearby Keflavík.
- Keflavík is the next town.
- Blue Lagoon is 20 minutes drive away.
- Reykjavik, the capital of Iceland, is close enough for a visit by bus if your layover is long enough.
If you're booking a ticket through KEF, one option to consider is to book a longer stopover for a few days. Icelandair actively encourages this, allowing you to book a 1–7 day stopover for the same price as a ticket with a short layover. A stopover of a few days would allow you to travel around the island a bit and explore some of Iceland's beautiful scenery.
