Fares bottom out in November around $252 and peak in August near $455, 81% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 6 hours outbound, on a 3-night trip — ticketed under AL, which on a connecting fare need not operate every leg. At $269 for 2,915 km each way, that works out to about $46 per 1,000 km flown. That is about the $43 per 1,000 km typical of medium-haul fares here. Across the 11 departure cities we track at a similar distance from Reykjavík, this fare ranks 10th — 3.1× the $86 we hold from Milan. For context, the middle fare among the 6 routes of similar length we watch out of Vienna is $245. The best time to be in Reykjavík: Jun–Aug · Feb–Mar (aurora).

We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 6 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under AL. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
No — these are cached fares found on real searches (this one on 17 October). 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.
