Cached-fare history: across 8 months, Sep is the cheapest for BKK → KIX. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in September around $286 and peak in April near $538 — a $252 spread across the 8 months we track. The cheapest itinerary we are tracking makes one stop and takes about 6.5 hours outbound, on a 13-night trip — ticketed under Juneyao Airlines, which on a connecting fare need not operate every leg. At $286 for 4,176 km each way, that works out to about $34 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Of the 3 departure cities we track at a similar distance from Osaka, this is the cheapest right now — 21% under the next one, Kuala Lumpur. It is also the 3rd cheapest of the 7 routes of similar length we watch out of Bangkok.

How far in advance should I book BKK → 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We do not publish a number for this, because we cannot measure it yet.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 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 Bangkok to Osaka?
The current cheapest fares involve a connection, ticketed under Juneyao 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.
