When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 20.5 hours outbound, on a 24-night trip — ticketed under Air Canada, which on a connecting fare need not operate every leg. At $1,051 for 10,816 km each way, that works out to about $49 per 1,000 km flown. That is about the $44 per 1,000 km typical of long-haul fares here. Across the 18 departure cities we track at a similar distance from Beijing, this fare ranks 16th — 2.0× the $521 we hold from Madrid. That puts it in the cheaper half of the 22 routes of similar length we watch out of Boston, where the middle fare is $1,090. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Beijing: Sep–Oct · Apr–May.

The median cached fare across this calendar is 24% higher than when tracking began on 8 Aug — $916 then versus $1,135 now, across 16 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $854, on 24 Nov.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
BOS → PEK, answered.
How far in advance should I book BOS → 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We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Boston to Beijing?
The current cheapest fares involve a connection, ticketed under Air Canada. 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.
