Cached-fare history: across 4 months, Nov is the cheapest for LIS → KEF. Best time to be there: Jun–Aug · Feb–Mar (aurora).
Fares bottom out in November around $219 and peak in December near $320 — a $101 spread across the 4 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 Ryanair, which on a connecting fare need not operate every leg. At $219 for 2,948 km each way, that works out to about $37 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Across the 11 departure cities we track at a similar distance from Reykjavík, this fare ranks 6th — 2.3× the $95 we hold from Milan. For context, the middle fare among the 11 routes of similar length we watch out of Lisbon is $147.

How far in advance should I book LIS → 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We do not publish a number for this, because we cannot measure it yet.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 4 months of cached fares, Nov comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Lisbon to Reykjavík?
The current cheapest fares involve a connection, ticketed under Ryanair. 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.
