When this route gets cheap.
Fares bottom out in May around $686 and peak in December near $1,511, 120% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 18 hours outbound, on a 7-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $686 for 11,125 km each way, that works out to about $31 per 1,000 km flown. That is below the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 14 departure cities we track at a similar distance from Beijing, this fare ranks 5th — 32% above the $521 from Madrid. That puts it in the cheaper half of the 21 routes of similar length we watch out of Washington, where the middle fare is $887. The best time to be in Beijing: Sep–Oct · Apr–May.

Good to know
WAS → PEK, answered.
Is $686 a good price for Washington to Beijing?
Yes — the seasonal median for this route is around $1,040 round-trip. At $686 you're 34% below that, which we rate great for this route.
What is the cheapest month to fly from Washington to Beijing?
Across 4 months of cached-fare history, May comes out cheapest on this route. The best months to actually be in Beijing are Sep–Oct · Apr–May — when those overlap, that's your window.
How far in advance should I book WAS → Beijing?
We do not publish a number for this, because we cannot measure it yet.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, May 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 Beijing?
The current cheapest fares involve a connection, ticketed under Korean Air. 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.
