Best time to be in Reykjavík: Jun–Aug · Feb–Mar (aurora). Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes one stop and takes about 4 hours outbound, on a 14-night trip — ticketed under Aer Lingus, which on a connecting fare need not operate every leg. At $303 for 1,506 km each way, that works out to about $101 per 1,000 km flown. That is above the $41 typical of short-haul fares here. For context, the middle fare among the 18 routes of similar length we watch out of Dublin is $104. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

DUB → KEF, answered.
How far in advance should I book DUB → Reykjavík?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Dublin to Reykjavík?
The current cheapest fares involve a connection, ticketed under Aer Lingus. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
