The cheapest itinerary we are tracking makes 2 stops and takes about 19.5 hours outbound, on a 2-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $808 for 8,409 km each way, that works out to about $48 per 1,000 km flown. That is about the $44 per 1,000 km typical of long-haul fares here. Across the 11 departure cities we track at a similar distance from Reykjavík, this fare ranks 4th — 29% above the $625 from Abu Dhabi. For context, the middle fare among the 45 routes of similar length we watch out of Seoul is $655. We have 1 month 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. Fare history here is still too short to name a cheap season. The best time to be in Reykjavík: Jun–Aug · Feb–Mar (aurora).

Route facts
Good to know
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
The current cheapest fares involve a connection, ticketed under Korean Air. 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.
