Google was wrong. There are two airports "in" Reykjavík: Reykjavík Airport, which is close to town and serves only domestic destinations and Greenland, and Keflavík International Airport, a.k.a. Reykjavík–Keflavík, which is 50km to the west and which has all the international flights.
At the time when the question was posted, if you searched Google ...
Yes, there will be restaurants open at that time. I took one of WOW's 6am flights just a few weeks ago and all of the restaurants were open by the time I got through security at around 4:40.
This is actually a very busy time for KEF airport as a lot of North American flights arrive between 4 and 6 and a lot of European flights depart between 6 and 8.
You have to catch Bus 55 to Reykjavik (you can catch the more expensive Flybus and Greyline shuttles if you want), from Reykjavik you can catch buses 51 to Selfoss.
The Reykjavík bus system, Strætó, runs buses to Selfoss. The route is number 51 and buses leave from Mjódd interchange station in Reykjavík, goes through Hveragerði and terminates at Fossnesti ...
There is a Schengen emigration control that you must pass through (if coming from a Schengen country. There is no security control (i.e. Metal detectors) that you normally must pass through. There are food vendors both before and after the control.
Car rental is the easiest when short on time but rental cars in Iceland are extremely expensive due to the short tourist season. One thing that is popular though is to rent a camper van which offset lodging costs.
Buses are available and go around the island and some do cross in the middle. They are relatively affordable and the routes are quite simple ...
Assuming that they layover is actually in Keflavik airport (which it almost certainly is; Reykjavik itself just has domestic flights, and a few connections to neighboring locations in the North Atlantic):
Yes, you can leave the airport during your layover. Since your destination is Finland, and both of Iceland and Finland are in the Schengen area, you'd be ...
I've hitchhiked for on week in Iceland. If you are on the ring road or in the main gravel roads (for example the F208 to Landmannalaugar), you shouldn't have to wait too much. There is one time where I waited for 2 hours, but other than that it was often 30 minutes max.
The bus system is pretty extensive and can bring you near where you want almost every ...
Yes, that's about right. 3 hours sounds eminently doable; it's not a large airport and most passengers transit anyway, so there are not huge security lines.
Of course, if your incoming flight from London is delayed and you don't make it, you'll be on your own, with your onwards ticket lost as a no-show. Flights to Narsarsuaq are only twice a week, and ...
At Keflavík, there are scheduled arrivals and departures as late as 2AM. The tax free shop is open 24h, but it is difficult to find the opening hours for the other shops, cafés and restaurants. At least Kaffitár, a coffee shop, is open until 1AM and serves snacks and light meals.
So yes, I've made my visit by now.
First, for sleeping
when arriving (at 1am) I took a flybus between Keflavik airport and BSI (the bus central station). Then I "slept" there (or I least I stayed there). Plenty of people were doing the same, but it wasn't so great (a lot of movements, not so much room, etc.). The BSI is open all night, with arrivals and ...
You have to leave bus 55 at Fjordur.
To get to Mjoddin you can take bus nr. 21
When you get to Mjoddin you change to bus nr. 51.
Less of a hassle but probably much more expensive is this https://www.re.is/flybus-south
Best of luck and safe travel.
The SAS Plus page you linked, does mention the access to lounges. However it does also note that this access is subject to availability.
The only lounge at Keflavik seems to be the Saga Lounge by Iceland Air. In its access rules, Iceland Air mentions Eurobonus Pandion when flying with SAS, and SAS Passengers on Business Class (C-class), but not SAS Plus ...
Here you can find the schedule from Reykjavik Excursions and as you can see during summer time they operate till 22.00 indeed. If you want to be sure, just arrange it with the bus driver on your way to Blue Lagoon from Reykjavik.
Happy visit to Iceland! :)
If you are travelling from London, then you are going to land on the International airport not the domestic one. This would be KEF and is approx. 30 miles (49.5 km) away from Reykjavík.
In terms of transportation, you can always hire a car on arrival, the rates aren't high and is economical too.
As stated by Timatic, the database used by check-in staff:
Visa required, except for Holders of confirmed onward tickets transiting on the same calendar day
So if your connection is on the same day, you do not need a visa
The website of the airport will tell you: it's 2.5 to 3 hours before the flight, depending on the airline. This is of course for an at the counter check in. Online check ins are often at least 24 hours before the flight. Many airlines also allow check ins at a kiosk, and they're open 24h/day.
I have been pulled aside by security ("SSSS" code on my boarding pass) when going from the Schengen to non-Schengen zone on my way to the US via Keflavík. I had my bags inspected, I was swabbed for residue, etc. The whole procedure took less than 10 minutes.
I would recommend heading to your gate first to make sure you have time, and then find a place to ...
