When this route gets cheap.
Fares bottom out in October around $184 and peak in February near $246, 34% dearer, across the 7 months we track. The cheapest itinerary we are tracking flies HK Express nonstop and takes about 3.5 hours outbound, on a 5-night trip. At $184 for 2,092 km each way, that works out to about $44 per 1,000 km flown. That is about the $41 per 1,000 km typical of short-haul fares here. That puts it in the cheaper half of the 7 routes of similar length we watch out of Hong Kong, where the middle fare is $184. The best time to be in Seoul: Apr–May · Sep–Oct.

Good to know
HKG → SEL, answered.
Is $184 a good price for Hong Kong to Seoul?
Yes — the seasonal median for this route is around $245 round-trip. At $184 you're 25% below that, which we rate good for this route.
What is the cheapest month to fly from Hong Kong to Seoul?
Across 7 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Seoul are Apr–May · Sep–Oct — when those overlap, that's your window.
How far in advance should I book HKG → Seoul?
We do not publish a number for this, because we cannot measure it yet.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 7 months of cached fares, Oct comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Hong Kong to Seoul?
Yes — the current board includes nonstop fares (HK Express). The outbound leg runs around 3.5 hours.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
