Cached-fare history: across 9 months, Sep is the cheapest for SEL → HKT. Best time to be there: Nov–Mar.
Fares bottom out in September around $247 and peak in April near $471 — a $224 spread across the 9 months we track. The cheapest itinerary we are tracking makes one stop and takes about 7.5 hours outbound, on a 4-night trip — ticketed under Vietnam Airlines, which on a connecting fare need not operate every leg. At $247 for 4,375 km each way, that works out to about $28 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Phuket, this fare ranks 2nd — 19% above the $208 from Shanghai. That puts it in the cheaper half of the 8 routes of similar length we watch out of Seoul, where the middle fare is $252.

Across 9 months of cached-fare history, Sep 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 SEL → 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We do not publish a number for this, because we cannot measure it yet.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 9 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Seoul 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.
