Cached-fare history: across 4 months, Oct is the cheapest for BOS → WAW. Best time to be there: May–Sep.
Fares on this route stay within about $63 across the 4 months we track — season matters less here than timing the drop. The cheapest itinerary we are tracking makes one stop and takes about 8.5 hours outbound, on a 14-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $698 for 6,552 km each way, that works out to about $53 per 1,000 km flown. That is above the $44 typical of long-haul fares here. Across the 10 departure cities we track at a similar distance from Warsaw, this fare ranks 8th — 2.0× the $342 we hold from New York. For context, the middle fare among the 33 routes of similar length we watch out of Boston is $679.

BOS → WAW, answered.
Is $698 a good price for Boston to Warsaw?
Only slightly. The seasonal median is around $740 round-trip and this fare is 6% under it, about $42. 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 Boston to Warsaw?
Across 4 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Warsaw are May–Sep — when those overlap, that's your window.
How far in advance should I book BOS → Warsaw?
We do not publish a number for this, because we cannot measure it yet.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, Oct comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Boston to Warsaw?
The current cheapest fares involve a connection, ticketed under SAS. 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.
