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 flies Icelandair nonstop and takes about 5.5 hours outbound, on a 5-night trip. At $445 for 3,877 km each way, that works out to about $57 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 11 departure cities we track at a similar distance from Reykjavík, this fare ranks 9th — 2.5× the $175 we hold from Barcelona. That puts it in the cheaper half of the 6 routes of similar length we watch out of Boston, where the middle fare is $445. We have 3 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.

BOS → KEF, answered.
How far in advance should I book BOS → 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We do not publish a number for this, because we cannot measure it yet.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 Boston to Reykjavík?
Yes — the current board includes nonstop fares (Icelandair). The outbound leg runs around 5.5 hours.
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.
