Good to know
SEL → KIX, answered.
Is $152 a good price for Seoul to Osaka?
Yes — the seasonal median for this route is around $200 round-trip. At $152 you're 24% below that, which we rate good for this route.
What is the cheapest month to fly from Seoul to Osaka?
Across 10 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Osaka are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book SEL → Osaka?
We do not publish a number for this, because we cannot measure it yet.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 10 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Seoul to Osaka?
Yes — the current board includes nonstop fares (T'way Air). The outbound leg runs around 2 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.
