Across 8 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Hong Kong are Oct–Dec — when those overlap, that's your window.
How far in advance should I book SEL → 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We do not publish a number for this, because we cannot measure it yet.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, 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 Hong Kong?
Yes — the current board includes nonstop fares (Eastar Jet). The outbound leg runs around 3.5 hours.
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.
