Frankfurt to Seoul is one of Germany’s best-served long-haul routes to East Asia, with a real choice of non-stop carriers covering the roughly 11-hour flight. This guide covers who flies the route, what a fair return fare looks like in euros, and when to book to land the best price.
Route: Frankfurt (FRA) → Seoul–Incheon (ICN)
Distance: approximately 8,570 km (5,325 miles)
Non-stop flight time: about 11h 00m – 11h 20m eastbound
Direct flights: Yes — Lufthansa, Korean Air, Asiana and T’way Air fly non-stop. One-stop options are cheaper, but by less than you might expect: China Eastern via Shanghai was €535–€588 and took nearly two thirds of the cheap fares, while T’way Air’s non-stop was €597–€627 and Lufthansa’s €805–€920.
Fares from Frankfurt to Seoul (EUR)
Seoul is a year-round city destination, but fares climb around the East Asian peaks — spring cherry-blossom season (late March–April), the summer holidays (July–August), and the autumn foliage weeks — and over the Christmas/New Year period. The quieter winter and early-spring months are the cheapest. The figures below are typical economy return fares in euros; the lowest are usually one-stop itineraries, with non-stops sitting toward the higher end.
| Month | Demand | What to expect |
|---|---|---|
| January | — | medium |
| February | — | medium |
| March | — | medium-high (blossom) |
| April | — | high (blossom) |
| May | — | medium |
| June | — | medium |
| July | — | high (holidays) |
| August | — | high (holidays) |
| September | — | medium |
| October | — | medium-high (foliage) |
| November | — | low-medium |
| December | — | very high (holidays) |
Checked against every return fare on sale as we write, two anchors hold: a typical fair price is roughly €600 (the median is €577) and anything under about €550 is worth booking quickly (only a fifth of fares are under €563). Two corrections: nothing sells below €535, and the high-800s figure usually quoted as everyday is really the Lufthansa non-stop (€805–€920). The cheap fares are China Eastern through Shanghai from €535 — and T’way Air’s direct flight at €597 is only about €60 more.
Airlines on this route
Non-stop (about 11 hours):
- T’way Air — a lower-cost non-stop and the cheapest direct fare in our check at €597–€627, only about €60 above the cheapest connection. Lighter onboard product and add-on bags.
- Lufthansa — the most frequent non-stop, Frankfurt → Incheon several times a week with wide Star Alliance connections across Germany, at €805–€920.
- Korean Air — South Korea’s flag carrier, a strong hard product on wide-body aircraft and a full-service onward network from Seoul.
- Asiana Airlines — non-stop service with well-rated economy; note Asiana is being merged into Korean Air, so check the operating carrier at booking.
- T’way Air — a lower-cost non-stop option on the 787, often the cheapest of the direct fares, but with a lighter onboard product and add-on bags.
One-stop (usually the cheapest, about 14–18 hours total):
- Emirates via Dubai, Qatar Airways via Doha and Etihad via Abu Dhabi — frequent Gulf routings with strong economy and often the best-value fares.
- Turkish Airlines via Istanbul and Finnair via Helsinki — competitive one-stops with a shorter first leg from Frankfurt.
The one-stop carriers compete hard and usually undercut the non-stops by €80–€200. If time matters most, book a non-stop; if price is the priority, a single stop through the Gulf, Istanbul or Helsinki is the sweet spot.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and choice; long-haul fares to Seoul rarely improve in the final weeks.
- Avoid the peaks: cherry-blossom April, the July–August summer holidays and the Christmas/New Year weeks are the priciest — shift a week or two either side to save.
- Consider T’way for the lowest non-stop, but price the all-in fare with bags and seats, as its light fares strip those out.
- Compare a Gulf or Helsinki connection if budget beats speed — the one-stops are usually the cheapest headline fares.
- Check checked-bag rules: the full-service carriers include 1–2 pieces to Seoul, but the cheapest fares on some carriers don’t — compare the total.
Arriving in Seoul
Non-stop flights land at Incheon International (ICN), about 50 km west of central Seoul and consistently rated one of the world’s best airports. The fastest way in is the AREX airport railway: the all-stop line reaches central Seoul Station in around 60 minutes for roughly €3–€5, while the direct express is a little faster and dearer. Airport limousine buses serve most districts and hotels, and a taxi to the centre runs roughly €40–€60 plus any tolls. A handful of regional and budget flights use the older Gimpo (GMP) airport, closer to the city — check which one your ticket uses.

Yes. Lufthansa, Korean Air, Asiana Airlines and T’way Air all fly non-stop from Frankfurt to Incheon. If you’d rather save money the cheapest connection in our fare check was China Eastern via Shanghai at €535 — but the saving is small: T’way Air’s non-stop was €597, about €60 more for three fewer hours in transit. Lufthansa was €805–€920.

Which airlines fly from Frankfurt to Seoul?
Non-stop: T’way Air (€597–€627), Lufthansa (€805–€920), Korean Air and Asiana; the last two did not appear among the cheapest fares when we checked. One-stop, cheapest first: China Eastern via Shanghai (€535–€588, the floor and nearly two thirds of the cheapest fares), Air China via Beijing (€555–€603), Air France via Paris (€646), KLM via Amsterdam (€656) and Qatar Airways via Doha (€984 — the dearest fare we found). Emirates, Etihad, Turkish Airlines and Finnair also sell the route but none appeared among the cheapest. The low fares here are Chinese, not Gulf.
Which airport do I fly into in Seoul?
Almost all long-haul flights land at Incheon International (ICN), Seoul’s main international gateway about 50 km west of the city. Some regional and budget services use Gimpo (GMP) instead, which is closer in — check your ticket before arranging onward transport.
How far in advance should I book Frankfurt to Seoul flights?
Aim to book 2 to 4 months ahead. Long-haul fares to Seoul tend to rise as departure approaches, especially around the spring blossom season, the summer holidays and the Christmas peak, so early booking almost always wins.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than Friday-to-Sunday, and flying out and back on weekdays can save €40–€120 on a return. Being flexible by a day or two is one of the easiest ways to cut the fare.
