Cached-fare history: across 5 months, Feb is the cheapest for WAS → PEK. Best time to be there: Sep–Oct · Apr–May.
Fares bottom out in February around $656 and peak in October near $1,238 — a $582 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 18.5 hours outbound, on a 7-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $656 for 11,125 km each way, that works out to about $29 per 1,000 km flown. That is below the $40 typical of ultra-long-haul fares here. Across the 15 departure cities we track at a similar distance from Beijing, this fare ranks 4th — 23% above the $534 from Sydney. That puts it in the cheaper half of the 22 routes of similar length we watch out of Washington, where the middle fare is $966.

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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Feb comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Washington to Beijing?
The current cheapest fares involve a connection, ticketed under Korean Air. 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.
