Madrid to Seoul is a long-haul route with one true non-stop option and plenty of well-priced connections. Korean Air flies the 13-hour non-stop from Barajas, while Gulf and European carriers usually undercut it with a single stop. This guide covers who flies the route, what a fair return fare looks like in euros, and when to book to save.
Route: Madrid (MAD) → Seoul Incheon (ICN)
Distance: approximately 9,900 km (6,150 miles)
Non-stop flight time: about 13 hours eastbound
Direct flights: Yes — Korean Air flies non-stop from Madrid (around four times weekly), at €980–€1,094 in our fare data. One-stop options are not merely cheaper but roughly half the price, and they are Chinese rather than Gulf: China Southern via Guangzhou at €519–€592 took well over half the cheapest fares, and Sichuan Airlines via Chengdu held the floor at €518.
Fares from Madrid to Seoul (EUR)
Seoul is a year-round city break, but fares track Korea’s peak travel windows. Spring cherry-blossom season (late March–April), the European summer holidays and the autumn foliage weeks push prices up; deep winter and the shoulder months are the cheapest. The figures below are typical economy return fares in euros — the lowest are usually one-stop itineraries, with Korean Air’s non-stop sitting toward the higher end.
| Month | Demand | What to expect |
|---|---|---|
| January | — | medium |
| February | — | medium (Lunar New Year spike) |
| March | — | medium-high |
| April | — | high (cherry blossom) |
| May | — | medium-high |
| June | — | medium |
| July | — | high (summer holidays) |
| August | — | high |
| September | — | medium |
| October | — | high (autumn foliage) |
| November | — | medium |
| December | — | high (holidays) |
Checked against every return fare on sale as we write, a typical fair price is roughly €520 — almost exactly the floor, which is €518, with a median of €554 and four fares in five under €689. So the everyday price is the mid-500s and a genuinely good return is under about €529; there is nothing in the €400s to wait for. The non-stop is a different proposition from the one the page usually implies: Korean Air was €980–€1,094, roughly twice a connection.
Airlines on this route
Non-stop (about 13 hours):
- Korean Air — the only non-stop from Madrid to Incheon, around four times a week; SkyTeam member with a solid long-haul economy product.
One-stop (usually the cheapest, about 15–19 hours total):
- China Southern via Guangzhou — the value routing on this pair by a distance: €519–€592 return and well over half the cheapest fares we found, in about 17h 50m.
- Sichuan Airlines via Chengdu — held the outright floor at €518–€586, on a slightly longer 19h 25m itinerary.
- Air China via Beijing — €586, and the quickest connection at about 14h 25m.
- Qatar Airways via Doha (€689), KLM via Amsterdam (€703–€802), Air France via Paris (€735), Finnair via Helsinki (€825) and Turkish Airlines via Istanbul (€836) — comfortable alternatives, but a clear step up in price.
- Emirates via Dubai, Etihad via Abu Dhabi and Lufthansa via Frankfurt or Munich — all sell the route, though none appeared among the cheapest fares when we checked.
Because the one-stop carriers compete hard, they undercut the non-stop by far more than a modest margin — about €460 at the floor in our check, or roughly half the price. If time matters most, book Korean Air; if price is the priority, a single stop through Guangzhou, Chengdu or Beijing is the sweet spot, and Beijing is also the fastest of the three.
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 fall in the final weeks.
- Avoid the peaks — cherry-blossom April, the July–August summer holidays and the autumn foliage weeks are the priciest.
- Travel in the shoulder (May, June, September or November) for the lowest fares and the most comfortable weather.
- Check checked-bag rules: Korean Air and the Gulf carriers usually include a generous checked allowance to Seoul; the cheapest “light” fares may not, so compare the all-in price.
- Watch the Lunar New Year and Chuseok holidays — Korean public holidays can spike fares by a week or two, so shift your dates if you can.
Arriving in Seoul
Almost all international flights land at Incheon International (ICN), about 50 km west of central Seoul. The easiest way in is the AREX Airport Railroad: the all-stop train reaches Seoul Station in around 60 minutes for well under €5, while the express takes about 45 minutes. A metered taxi to the centre runs roughly €40–€60 depending on traffic. Some regional and budget flights use the older Gimpo (GMP) airport, which is closer to the city — check which one your ticket uses.
