When this route gets cheap.
Fares bottom out in October around $491 and peak in January near $762, 55% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 14 hours outbound, on a 8-night trip — ticketed under China Eastern, which on a connecting fare need not operate every leg. At $491 for 8,560 km each way, that works out to about $29 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 18 departure cities we track at a similar distance from Frankfurt, this fare ranks 2nd — 18% above the $417 from San Francisco. It is also the 2nd cheapest of the 46 routes of similar length we watch out of Seoul. The best time to be in Frankfurt: May–Sep.

Good to know
SEL → FRA, answered.
Is $491 a good price for Seoul to Frankfurt?
Yes — the seasonal median for this route is around $760 round-trip. At $491 you're 35% below that, which we rate great for this route.
What is the cheapest month to fly from Seoul to Frankfurt?
Across 4 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Frankfurt are May–Sep — when those overlap, that's your window.
How far in advance should I book SEL → Frankfurt?
We do not publish a number for this, because we cannot measure it yet.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 4 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 Seoul to Frankfurt?
The current cheapest fares involve a connection, ticketed under China Eastern. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
