Good to know
BOS → KEF, answered.

What is the cheapest month to fly from Boston to Reykjavík?
Across 5 months of cached-fare history, Feb 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 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 5 months of cached fares, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
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 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.
