Cached-fare history: across 8 months, Jan is the cheapest for SF → HKG. Best time to be there: Oct–Dec.
Fares bottom out in January around $452 and peak in July near $1,007 — a $555 spread across the 8 months we track. The cheapest itinerary we are tracking makes one stop and takes about 17 hours outbound, on a 20-night trip — ticketed under Philippine Airlines, which on a connecting fare need not operate every leg. At $452 for 11,096 km each way, that works out to about $20 per 1,000 km flown. That is well under the $40 that ultra-long-haul fares on this board typically run. Across the 27 departure cities we track at a similar distance from Hong Kong, this fare ranks 2nd — 3% above the $437 from London. That puts it in the cheaper half of the 52 routes of similar length we watch out of San Francisco, where the middle fare is $804.

How far in advance should I book SF → 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 8 months of cached fares, Jan comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from San Francisco to Hong Kong?
The current cheapest fares involve a connection, ticketed under Philippine Airlines. 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.
