Reykjavik Keflavik KEF: the complete layover guide

Landside: check in and the 24 hour basics

The check in hall occupies the departures level and moves quickly outside the morning and afternoon waves. Landside services are thin but reliable: a 10/11 convenience store in the public area is reported by travelers to run around the clock, which makes it the overnight fallback for food and drinks when airside outlets close. Car rental desks, the Flybus stop and taxis all sit within a short walk of the arrivals doors.

The Schengen airside: A and C gates

Past security you land in the main duty free and dining run, which the 2024 expansion made noticeably better, with a new dining area and more seating. The recliner style seats near the windows along the A and C piers are the best free real estate in the building, and power outlets and shared charging stations are easy to find. Free unlimited wifi covers the whole terminal.

The Icelandair Saga Lounge is the only full lounge at Keflavik. It sits on the second floor inside the Schengen zone, up the stairs next to the D zone border control, which makes it reachable before passport control whichever wing you depart from. At roughly 15,000 square feet with showers, a buffet and design built around Icelandic stone and timber, it is a genuinely good room. Access is the catch: it serves Saga Premium passengers and Icelandair Saga Club Gold and Silver members plus their guests, it is not in the Priority Pass network, and it does not sell walk up entry. Reviews from 2025 put its hours at roughly 05:00 to 01:00, tracking the flight banks; confirm on the day.

Priority Pass at KEF: dining credits, not lounges

Priority Pass holds no lounge door at Keflavik. Instead the card buys ISK 3,350 off the bill at two airside restaurants. Elda, in the North Building near duty free, opens at 04:00 daily and runs until the evening, with closing times that vary by day. Jomfruin, on the second floor of the North Building, serves Danish and Scandinavian dishes from 04:00 to 18:00. Both serve international and in transit passengers, both accept the digital card, and both may turn the card away when the room is full, so treat the credit as a discount on a meal you wanted anyway rather than a lounge substitute.

The D gates: the non Schengen wing

Beyond the D zone passport control on level 1 you find a second round of shopping and dining, so clearing early does not strand you in a holding pen. Icelandair staffs service desks by gate D15 on the first floor and by gate C22 on the second whenever its flights operate, useful for reprinting a boarding pass mid connection. Seating in the D wing fills hard ahead of the late afternoon North America bank.

The overnight reality

The terminal stays open 24 hours and you can wait inside overnight with a valid onward ticket. What you cannot do is sleep well. There are no rest zones, no sleep pods and no hotel inside the building, and posted signs discourage sleeping, though travelers consistently report that security leaves ticketed passengers alone. The quietest window runs roughly 01:00 to 04:00, after the last evening departures and before check in opens for the early morning wave; the recliner seats by the windows airside are the prize, and they go early. For a flat bed, the Courtyard by Marriott sits a short walk from the terminal. Book it for any layover that crosses 02:00, because the 04:00 noise returns fast.
