Cached-fare history: across 5 months, Jan is the cheapest for FRA → KEF. Best time to be there: Jun–Aug · Feb–Mar (aurora).
Fares bottom out in January around $280 and peak in December near $378 — a $98 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 5 hours outbound, on a 5-night trip — ticketed under Cityjet, which on a connecting fare need not operate every leg. At $280 for 2,401 km each way, that works out to about $58 per 1,000 km flown. That is above the $41 typical of short-haul fares here. Across the 15 departure cities we track at a similar distance from Reykjavík, this fare ranks 14th — 2.9× the $95 we hold from Milan. For context, the middle fare among the 11 routes of similar length we watch out of Frankfurt is $160.

FRA → KEF, answered.
Is $280 a good price for Frankfurt to Reykjavík?
Only slightly. The seasonal median is around $335 round-trip and this fare is 16% under it, about $55. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Frankfurt to Reykjavík?
Across 5 months of cached-fare history, Jan comes out cheapest on this route. The best months to actually be in Reykjavík are Jun–Aug · Feb–Mar (aurora) — when those overlap, that's your window.
How far in advance should I book FRA → 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 5 months of cached fares, Jan comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Frankfurt to Reykjavík?
The current cheapest fares involve a connection, ticketed under Cityjet. 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.
