Dublin to Reykjavik is a short, scenic hop — under three hours non-stop — that opens up Iceland’s waterfalls, geysers and Northern Lights without a long-haul day. Icelandair flies the route direct, with the most frequency in the summer months. This guide covers who flies it, what a fair return fare looks like in euro, and when to book for the best price.
Route: Dublin (DUB) → Reykjavik–Keflavik (KEF)
Distance: approximately 1,500 km (935 miles)
Non-stop flight time: about 2h 35m
Direct flights: Yes — Icelandair flies non-stop from Dublin to Keflavik, several times a week and most frequently in summer, at €234 and up. One-stop options via London or Amsterdam are cheaper, not dearer — €169–€218 on Ryanair and easyJet — but they turn a 2h35m hop into most of a day, so the non-stop is usually still worth the extra €40–€60.
Fares from Dublin to Reykjavik (EUR)
Iceland’s fares swing hard with the seasons. The summer high season (June–August), when the days are long and every road is open, is the priciest and busiest; the shoulder months and deep winter are far cheaper, and winter is prime time for the Northern Lights. The figures below are typical economy return fares in euro — the lowest are hand-luggage fares booked well ahead.
| Month | Demand | What to expect |
|---|---|---|
| January | — | low-medium (aurora season) |
| February | — | low-medium (aurora season) |
| March | — | medium |
| April | — | medium |
| May | — | medium-high |
| June | — | high |
| July | — | very high |
| August | — | very high |
| September | — | medium |
| October | — | medium |
| November | — | low |
| December | — | medium-high (holiday peak) |
Checked against every return fare on sale as we write, this route costs more than it is usually described — and the cheapest option is not the direct. Connections run €169–€218 on Ryanair and easyJet, median €202; Icelandair’s non-stop starts at €234, median €259. So a return under about €190 is a genuinely good one, and a direct under about €250 is worth taking for the saved hours. There is nothing under €169. Flight frequency thins out in the off-season, so cheap dates can be limited.
Airlines on this route
Non-stop (about 2h 35m):
- Icelandair — the main carrier on the route, Dublin → Keflavik non-stop, with the most departures in the summer season and a lighter schedule over winter.
One-stop (occasionally cheaper, about 6–10 hours total):
- European legacy carriers via London, Amsterdam or a Scandinavian hub — connecting itineraries that can help on dates when the non-stop is full or dear, though they turn a short hop into a long day.
On such a short route the non-stop is nearly always both faster and better value, so a connection only makes sense if the Icelandair direct flight is sold out or unusually expensive on your dates.
When to book & how to save
- Book 2–4 months ahead for summer — June to August fills up early and rarely gets cheaper close in.
- Travel in the shoulder or winter (October–April) for the lowest fares and, from autumn onwards, a real shot at the Northern Lights.
- Be flexible on dates — the off-season schedule is only a few flights a week, so a day either way can be the difference between a great fare and none at all.
- Pack light — the cheapest fares are cabin-bag only; if you can travel with hand luggage you’ll unlock the lowest prices.
- Budget for Iceland on the ground — the flight can be cheap, but car hire, food and tours are not, so the airfare is only part of the trip cost.
Arriving in Reykjavik
Flights land at Keflavik International (KEF), about 50 km southwest of Reykjavik — the city centre is not next door, so plan the transfer. The Flybus and similar airport coaches run in step with arriving flights to the BSI bus terminal and many hotels, taking roughly 45–60 minutes for around €25–€35 each way. A taxi is far dearer (often €120 or more), so most visitors take the coach or pick up a hire car at the terminal, which is also handy for the Blue Lagoon on the way into town.
Frequently asked questions
How long is the flight from Dublin to Reykjavik?
The non-stop flight takes about 2 hours 35 minutes each way — one of the shortest routes to Iceland from these islands. A one-stop itinerary via London, Amsterdam or a Scandinavian hub turns it into a 6 to 10 hour journey, so the direct flight is well worth it if it’s available on your dates.
Are there direct flights from Dublin to Reykjavik?
Yes. Icelandair flies non-stop from Dublin to Keflavik, with the most frequency in the summer months and a lighter schedule over winter. It’s the main carrier on the route. On such a short hop the non-stop is almost always the best value, so a connecting flight is only worth it if the direct is full.
How much does it cost to fly from Dublin to Reykjavik?
A typical economy return runs about €190–€300 depending on the season and whether you connect, with the whole sample spanning €169–€1,173. The best hand-luggage deals are connections at €169–€218; Icelandair’s non-stop runs from €234. July and August — peak summer — sit at the top of the range.
What is the cheapest month to fly from Dublin to Reykjavik?
January, February and November are usually the cheapest. In the dates we could price, connecting returns started at €169 and the Icelandair non-stop at €234. The bonus is that autumn and winter are the Northern Lights season. Avoid June to August, which is peak summer and the priciest time to fly.
Which airlines fly from Dublin to Reykjavik?
Non-stop, the route is served by Icelandair, at €234 and up. Connections are cheaper than the direct here rather than a fallback: Ryanair (€169–€218, behind most of the cheap fares) and easyJet (€180–€216), with Lufthansa higher at €321–€418. They do make for a much longer day on such a short route, so weigh roughly €40–€60 saved against several extra hours — on a weekend break the direct usually still wins.
Which airport do I fly into in Reykjavik?
You land at Keflavik International (KEF), Iceland’s main international gateway, about 50 km southwest of the city. (The small Reykjavik City Airport nearby handles domestic and Greenland flights only.) From Keflavik, the Flybus coach or a hire car is the usual way into Reykjavik and out to the sights.
How far in advance should I book Dublin to Reykjavik flights?
Aim to book 2 to 4 months ahead for summer, which sells out early on a route that only runs a few times a week off-season. For winter and shoulder-season travel you can sometimes find good fares closer in, but limited frequency means the cheapest dates go quickly, so earlier is safer.
Is it cheaper to fly on weekdays?
Sometimes, yes — where the schedule offers a choice, midweek departures can be a little cheaper than Friday-to-Sunday flights. But because the route runs only a few times a week outside summer, availability matters more than the day of the week, so grab the best-priced flight that fits rather than holding out for a specific weekday.
