Destination briefBUDBudapestThermal baths, ruin bars and a river splitting two cities — still the best value capital in Europe.Best windowApr–Jun · Sep–OctAirportsFerenc Liszt (BUD)All routes into BudapestWhen this route gets cheap.
Best time to be in Budapest: Apr–Jun · Sep–Oct. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes one stop and takes about 15 hours outbound, on a 27-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $541 for 8,169 km each way, that works out to about $33 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Of the 17 departure cities we track at a similar distance from Budapest, this is the cheapest right now — though Toronto is within a few dollars. That puts it in the cheaper half of the 41 routes of similar length we watch out of Seoul, where the middle fare is $670. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

SEL → BUD, answered.
How far in advance should I book SEL → Budapest?
We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Seoul to Budapest?
The current cheapest fares involve a connection, ticketed under Air China. 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.
