When this route gets cheap.
Fares bottom out in January around $651 and peak in December near $1,287, 98% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 12.5 hours outbound, on a 4-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $651 for 6,166 km each way, that works out to about $53 per 1,000 km flown. That is above the $44 per 1,000 km typical of long-haul fares here. Across the 9 departure cities we track at a similar distance from Paris, this fare ranks 9th — 3.0× the $220 we hold from Abu Dhabi. That puts it in the cheaper half of the 24 routes of similar length we watch out of Washington, where the middle fare is $713. The best time to be in Paris: Apr–Jun · Sep–Oct.

Good to know
WAS → PAR, answered.
Is $651 a good price for Washington to Paris?
Yes — the seasonal median for this route is around $940 round-trip. At $651 you're 31% below that, which we rate great for this route.
What is the cheapest month to fly from Washington to Paris?
Across 5 months of cached-fare history, Jan comes out cheapest on this route. The best months to actually be in Paris are Apr–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book WAS → Paris?
We do not publish a number for this, because we cannot measure it yet.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, Jan comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Washington to Paris?
The current cheapest fares involve a connection, ticketed under United. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
