Keflavik International Airport (KEF)
Reykjavik, Iceland
Overview
Keflavík International Airport (KEF) is Iceland's gateway for virtually all international traffic — and the first thing to internalize is that it is not in Reykjavík. The airport sits on the Reykjanes peninsula about 50 km from the capital, there is no train, and the transfer takes 45–60 minutes by coach or car. Airport coaches (Flybus and Airport Direct are the established operators) meet every arrival including the middle-of-the-night ones, sell tickets online and in the terminal, and are the standard answer; taxis exist but are startlingly expensive over this distance.
The terminal is a single building that has grown in stages, and it shows: perfectly pleasant off-peak, genuinely congested during the two daily banks when Icelandair's transatlantic model funnels dozens of flights through within a couple of hours — typically early morning (Europe-bound) and mid-afternoon (North America-bound). If you're flying in those windows, the two-hour advice is real, security and passport queues included. US-bound departures get additional document checks at the gate, so don't drift off to the far cafés at boarding time.
Two genuinely useful local quirks: the arrivals duty-free store is where locals and savvy visitors buy alcohol, because it is dramatically cheaper than Iceland's state liquor stores — stock up on the way in, not out. And the Blue Lagoon sits roughly midway between the airport and Reykjavík, so scheduling it for your arrival or departure day (both coach companies offer luggage-friendly stopovers) saves a round trip. Iceland is in Schengen, so onward European connections skip passport control; North American arrivals clear immigration here.
Terminals
A single terminal built in expanding phases — compact enough that everything is walkable, but tight during the twice-daily transatlantic connection banks (early morning and mid-afternoon), when seating and food outlets run short. D gates involve the longest walk and are used for many non-Schengen/US departures. No terminal-change complexity.
Transport to city center
Airport coaches are the default: Flybus and Airport Direct meet all arrivals (including overnight ones), take 45–60 minutes to Reykjavík, and offer hotel drop-off options — booking online in advance is slightly cheaper and guarantees a seat at peak times. Car hire is the other mainstream choice given most visitors tour beyond the capital; the rental center involves a short shuttle. Taxis over this distance are very expensive and rarely worth it. Public bus route 55 exists and is cheapest, but it's slow and infrequent — fine on a loose schedule, risky before a flight.
Lounges
The main lounge airside serves Icelandair premium passengers plus Priority Pass and paid entry. It fills to capacity during the two daily connection banks — exactly when you'd want it — so treat access as a bonus rather than a plan. Outside the banks the terminal itself is calm enough that the lounge matters less.
Travel tips
Buy alcohol at arrivals duty-free — it's the cheapest legal alcohol in Iceland by a wide margin. Book your airport coach online before you land, and if the Blue Lagoon is on your list, schedule it as an airport-day stopover to avoid backtracking. Flying in the morning Europe bank or afternoon America bank, arrive a full two hours early; off-bank, KEF is quick. In winter, allow weather margin for the road from Reykjavík — storms occasionally slow or close it, and the coaches adjust but your timing should too.
Airport Wi-Fi
Free unlimited Wi-Fi throughout the terminal on the official network — fast enough for calls, no registration friction.
Security and arrival
Iceland is in Schengen: arriving from Europe's Schengen zone there's no passport control, while North American arrivals clear immigration at KEF — queues concentrate around the morning arrival bank. US-bound flights add gate-area document checks, so be at the gate when boarding opens. On arrival, use the duty-free store before customs: personal allowances for alcohol are worth using, since prices in town are far higher.
Distance to city
About 50 km southwest of Reykjavík on the Reykjanes peninsula — 45–60 minutes by airport coach or car. There is no rail link.
