Destination briefHKTPhuketThailand’s busiest beach island — crowded where the road goes, empty where the boat does.Best windowNov–MarAirportsPhuket (HKT)All routes into PhuketWhen this route gets cheap.
Cached-fare history: across 6 months, Mar is the cheapest for SF → HKT. Best time to be there: Nov–Mar.
Fares bottom out in March around $488 and peak in November near $1,019 — a $531 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 18.5 hours outbound, on a 16-night trip — ticketed under Vietnam Airlines, which on a connecting fare need not operate every leg. At $488 for 13,404 km each way, that works out to about $18 per 1,000 km flown. That is well under the $40 that ultra-long-haul fares on this board typically run. Of the 15 departure cities we track at a similar distance from Phuket, this is the cheapest right now — 9% under the next one, Dublin. That puts it in the cheaper half of the 32 routes of similar length we watch out of San Francisco, where the middle fare is $842.

Across 6 months of cached-fare history, Mar comes out cheapest on this route. The best months to actually be in Phuket are Nov–Mar — when those overlap, that's your window.
How far in advance should I book SF → Phuket?
We do not publish a number for this, because we cannot measure it yet.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 6 months of cached fares, Mar 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 Phuket?
The current cheapest fares involve a connection, ticketed under Vietnam 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.
