When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 22.5 hours outbound, on a 7-night trip — ticketed under Alaska Airlines, which on a connecting fare need not operate every leg. At $1,110 for 12,803 km each way, that works out to about $43 per 1,000 km flown. That is about the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 15 departure cities we track at a similar distance from Hong Kong, this fare ranks 11th — 2.4× the $457 we hold from London. That puts it in the cheaper half of the 27 routes of similar length we watch out of Boston, where the middle fare is $1,110. We have 1 month 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 Hong Kong: Oct–Dec.

The median cached fare across this calendar is 93% higher than when tracking began on 8 Aug — $1,119 then versus $2,165 now, across 12 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 $970, on 24 Oct.
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 → HKG, answered.
How far in advance should I book BOS → Hong Kong?
We do not publish a number for this, because we cannot measure it yet.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 Hong Kong?
The current cheapest fares involve a connection, ticketed under Alaska Airlines. 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 15 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.
