Best time to be in Guangzhou: Oct–Dec. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes one stop and takes about 16.5 hours outbound, on a 10-night trip — ticketed under Cathay Pacific, which on a connecting fare need not operate every leg. At $1,050 for 12,720 km each way, that works out to about $41 per 1,000 km flown. That is about the $40 typical of ultra-long-haul fares here. Across the 15 departure cities we track at a similar distance from Guangzhou, this fare ranks 11th — 2.0× the $530 we hold from San Francisco. That puts it in the cheaper half of the 26 routes of similar length we watch out of Boston, where the middle fare is $1,050. 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.

BOS → CAN, answered.
How far in advance should I book BOS → Guangzhou?
We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Boston to Guangzhou?
The current cheapest fares involve a connection, ticketed under Cathay Pacific. 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 August 24). 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.
