Copenhagen to Reykjavík is a short, scenic hop across the North Atlantic — non-stop in about 3½ hours, with Iceland’s dramatic landscapes, geothermal spas and northern lights waiting at the other end. Checking every return fare on sale, it costs more than most guides suggest: the cheapest non-stop is 1.790 kr. and the cheapest fare of any kind 1.347 kr. on a connection. This guide covers who really flies the route, what a return actually costs in kroner, and when to book to keep the cost down.

Fares from Copenhagen to Reykjavík (DKK)
Iceland’s high season is the bright Nordic summer, when demand and fares peak; the shoulder months and quieter winter weeks are much kinder on the wallet, apart from a Christmas and New Year spike. The figures below are typical economy return fares in kroner — the lowest reflect hand-baggage-only fares, with a checked bag adding to the total.
| Month | Demand | What to expect |
|---|---|---|
| January | — | medium (New Year, northern lights) |
| February | — | medium (northern lights) |
| March | — | medium |
| April | — | low-medium |
| May | — | medium (shoulder rising) |
| June | — | high |
| July | — | very high |
| August | — | high |
| September | — | medium |
| October | — | low-medium |
| November | — | low |
| December | — | high (Christmas & New Year) |
Checked against every return fare on sale as we write: the non-stop median is 1.813 kr., with SAS in a tight band at 1.790–1.855 kr. and Icelandair from 1.852 kr. So a direct return around 1.800 kr. is the going rate rather than a find, and under about 1.800 kr. is as good as the direct gets. The only cheaper fares are low-cost connections at 1.347 kr., which save roughly 450 kr. for a stop. There is nothing under a thousand kroner on this route.
Airlines on this route
Non-stop (about 3h 20m):
- Icelandair — the Iceland flag carrier and the route’s mainstay, with the most frequencies and a generous cabin bag on most fares; ideal if you want to add a stopover.
- SAS — non-stop from Copenhagen, full-service fares with EuroBonus points; frequencies rise sharply through the summer.
One-stop (rarely worth it):
- Norwegian — serves Copenhagen–Keflavík only via a connection, so it usually loses on both time and price against the two non-stops.
- Other European carriers — occasional connecting itineraries via a hub like Oslo or London; slower, and seldom cheaper than booking Icelandair or SAS direct.
For this route the choice is easy: with two airlines flying non-stop in under 3½ hours, a connection almost never pays off. Compare Icelandair and SAS on your dates and book whichever is cheaper — and note that Icelandair lets you break the journey with a free multi-day stopover if you’re travelling onward.
When to book & how to save
- Book 6–10 weeks ahead for shoulder-season trips, and 3–4 months ahead for June to August, when summer seats fill fastest and prices climb.
- Travel in the shoulder months — April, May, September and October offer the best mix of price, mild-ish weather and, in autumn/winter, a real shot at the northern lights.
- Skip peak summer and the Christmas/New Year window if budget matters; those are the most expensive weeks of the year to Iceland.
- Fly midweek: Tuesday to Thursday departures are usually cheaper than a weekend break, and shifting a day or two can save a few hundred kroner.
- Check the fare tier for bags: the lowest Icelandair and SAS fares may be cabin-only — add a checked bag before comparing the true all-in price.
Arriving in Reykjavík
Flights land at Keflavík International Airport (KEF), about 50 km southwest of Reykjavík — the domestic Reykjavík Airport (RKV) is not used for international arrivals. The simplest way into the city is the Flybus coach, which meets every flight and reaches Reykjavík in around 45 minutes for roughly 210 kr. (3.999 ISK) to the main terminal, with a hotel drop-off option for a little more. A taxi is far pricier at well over 1.000 kr., so most travellers take the bus or a pre-booked transfer.
Frequently asked questions
How long is the flight from Copenhagen to Reykjavík?
Non-stop flights take about 3 hours 20 minutes heading west to Keflavík, and a touch under that on the way home. A one-stop routing through another European city adds a couple of hours of connection time, so the direct services with Icelandair and SAS are much the quickest way to go.
Are there direct flights from Copenhagen to Reykjavík?
Yes. Icelandair and SAS both fly non-stop from Copenhagen to Keflavík, with multiple departures a day in summer. Norwegian only offers connecting itineraries on this route, so for a direct flight stick with Icelandair or SAS.
How much does it cost to fly from Copenhagen to Reykjavík?
A typical economy return runs about 1.350–2.000 kr., with the whole sample spanning 1.347–3.121 kr. Low-cost connections sit at the bottom at 1.347 kr.; the SAS non-stop is 1.790–1.855 kr. and Icelandair 1.852–3.121 kr. June to August and the Christmas/New Year peak push fares to the top of the range.
What is the cheapest month to fly from Copenhagen to Reykjavík?
April, October and November are usually the cheapest. In the dates we could price, non-stop returns started at 1.790 kr. and the cheapest connection at 1.347 kr. Avoid July and August, the summer peak, and the Christmas/New Year window in late December, which are the busiest and most expensive times to visit Iceland.
Which airlines fly from Copenhagen to Reykjavík?
Non-stop: SAS carried most of the cheap directs at 1.790–1.855 kr., with Icelandair at 1.852–3.121 kr. Norwegian serves the route only with a connection. The cheapest fares we found were low-cost connections on Wizz Air and Ryanair at about 1.350 kr., with LOT and Finnair connections higher at 2.120–2.587 kr. For most travellers SAS’s direct is the best balance — about 450 kr. more than the cheapest connection, for three and a bit hours instead of a stopover.
Which airport do I fly into in Reykjavík?
All international flights use Keflavík International Airport (KEF), around 50 km southwest of the capital. The small in-city Reykjavík Airport (RKV) handles domestic and Greenland/Faroe flights only, so your Copenhagen flight will always land at Keflavík.
How far in advance should I book Copenhagen to Reykjavík flights?
Aim for 6 to 10 weeks ahead in the shoulder seasons and 3 to 4 months ahead for summer. Iceland’s peak-season fares rise steadily as the popular June–August dates fill, so booking early is the surest way to lock in a good price.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than a Friday-out, Sunday-back weekend trip, and being flexible by a day or two can save 200–500 kr. on a return. Mixing a weekday out with a weekday back is one of the easiest ways to trim the fare.
