Fares bottom out in March around $579 and peak in January near $996, 72% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8.5 hours outbound, on a 7-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $579 for 6,552 km each way, that works out to about $44 per 1,000 km flown. That is about the $44 per 1,000 km typical of long-haul fares here. Across the 8 departure cities we track at a similar distance from Warsaw, this fare ranks 2nd — 51% above the $384 from New York. That puts it in the cheaper half of the 29 routes of similar length we watch out of Boston, where the middle fare is $693. The best time to be in Warsaw: May–Sep.

We do not publish a number for this, because we cannot measure it yet.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, Mar comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under SAS. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
