Fares bottom out in November around $588 and peak in August near $979, 66% dearer, across the 10 months we track. The cheapest itinerary we are tracking makes one stop and takes about 11.5 hours outbound, on a 14-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $588 for 8,275 km each way, that works out to about $36 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 24 departure cities we track at a similar distance from Seoul, this fare ranks 11th — 28% above the $458 from Istanbul. That puts it in the cheaper half of the 38 routes of similar length we watch out of Vienna, where the middle fare is $729. The best time to be in Seoul: Apr–May · Sep–Oct.

We do not publish a number for this, because we cannot measure it yet.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.
The current cheapest fares involve a connection, ticketed under Air China. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
