Brussels to Seoul is a long-haul run to one of Asia’s most rewarding cities, but there is no non-stop flight — every scheduled ticket connects once, most often through a European, Gulf or Chinese hub. This guide covers who flies the route, what a fair return fare looks like in euros, and when to book to reach South Korea for the least money.
Route: Brussels (BRU) → Seoul Incheon (ICN)
Distance: approximately 8,650 km (5,375 miles)
Non-stop flight time: no scheduled non-stop — one-stop journeys run about 14–19 hours in total (shortest around 13h 50m)
Direct flights: No — there is no scheduled non-stop from Brussels to Seoul. All fares connect once. On price the route belongs to Air China via Beijing, which carried four fifths of the cheapest fares at €511–€551; the European hubs are quicker but dearer, with Lufthansa via Frankfurt at €708–€1,102.
Fares from Brussels to Seoul (EUR)
Seoul is a year-round city, but fares track Korea’s travel seasons. Spring cherry-blossom weeks (late March to April), the autumn foliage of October, and the summer school holidays are the busiest and dearest; the winter months either side of the Christmas peak are usually the cheapest. The figures below are typical economy return fares in euros for a one-stop itinerary.
| Month | Demand | What to expect |
|---|---|---|
| January | — | medium |
| February | — | medium |
| March | — | medium-high |
| April | — | high (blossom) |
| May | — | high |
| June | — | medium |
| July | — | high (school holidays) |
| August | — | high |
| September | — | medium |
| October | — | high (foliage) |
| November | — | medium |
| December | — | high (holidays) |
Checked against every return fare on sale as we write, a typical fair price is roughly €520–€600 — the median is €515 and four fares in five are under €634, so that anchor holds. What does not hold is the idea of a fare in the 400s: the floor is €511, and a strong one-stop return is anything under about €515. The lowest “light” fares may not include a checked bag, which is charged separately.
Airlines on this route
There is no non-stop service, so every option below connects once. Turkish Airlines and the Chinese and Gulf carriers tend to post the lowest fares, while a European hub gives the shortest total time.
One-stop via Europe (usually the shortest):
- SWISS via Zurich — a single, tidy connection into Incheon.
- SAS via Copenhagen — frequent Scandinavian one-stop routing.
- Lufthansa via Frankfurt or Munich, and LOT Polish Airlines via Warsaw — more European hub options.
One-stop via the Gulf or China (often the cheapest):
- Turkish Airlines via Istanbul — the most frequent one-stop option and often keenly priced.
- Emirates via Dubai or Qatar Airways via Doha — strong economy on both legs.
- Air China via Beijing — usually among the lowest headline fares.
Because so many carriers compete, prices move around a lot: the Gulf, Chinese and Turkish routings usually undercut the European hubs by €50–€150, at the cost of a longer total journey. If time matters, a European one-stop is quickest; if price is the priority, cast the net wider.
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 last few weeks.
- Avoid the peaks: cherry-blossom season (late March–April), the October foliage weeks and the Christmas holidays are the busiest and most expensive.
- Aim for winter (January–February) outside the holidays for the lowest fares — Seoul is cold but the deals are real.
- Compare hubs: Istanbul, Doha, Dubai and Beijing routings swap the cheapest spot month to month, so check several.
- Check the bag rules: full-service carriers usually include 23–30 kg to Seoul, but the lowest “light” fares may not — compare the all-in price before booking.
Arriving in Seoul
International flights land at Incheon International (ICN), about 50 km west of central Seoul on its own island. The smooth, cheap way in is the AREX Airport Railroad — the all-stop train reaches Seoul Station in about an hour for well under €5, while the express is quicker for a little more. Airport limousine buses serve most neighbourhoods for roughly €7–€12, and a taxi to the centre runs closer to €40–€60 with tolls. The older Gimpo (GMP) airport mostly handles domestic and short regional flights.
Frequently asked questions
How long is the flight from Brussels to Seoul?
There is no non-stop flight, so plan on a one-stop journey of about 14 to 19 hours in total, with the fastest connections coming in around 13 hours 50 minutes. A quick change in Zurich, Frankfurt or Istanbul sits at the shorter end; a longer layover pushes the total up.
Are there direct flights from Brussels to Seoul?
No. There is no scheduled non-stop flight from Brussels to Seoul Incheon. Every ticket connects once — via a European hub such as Zurich, Copenhagen or Frankfurt for the shortest time, or via Air China (Beijing) for the lowest fares, which is where four fifths of the cheap fares we found were sold, from €511. Turkish Airlines (Istanbul), Emirates (Dubai) and Qatar Airways (Doha) also connect the route but were not among the cheapest when we checked.
How much does it cost to fly from Brussels to Seoul?
A typical economy return runs about €513–€634, median €515, with the cheap fares spanning €511–€1,102. The best one-stop deals start at €511 on Air China, while the European-hub carriers, the blossom, autumn and holiday peaks sit toward the top of that range.
What is the cheapest month to fly from Brussels to Seoul?
January, February and November are usually the cheapest. In the dates we could price, returns started at €511. Avoid April (cherry blossom), October (foliage) and the Christmas peak, which are the busiest and dearest.
Which airlines fly from Brussels to Seoul?
No airline flies it non-stop. Cheapest first in our fare data: Air China via Beijing (€511–€551, four fifths of the cheapest fares and the floor), KLM via Amsterdam (€634), LOT via Warsaw (€683–€701) and Lufthansa via Frankfurt (€708–€1,102, the dearest on the route but also the quickest). SWISS via Zurich, SAS via Copenhagen, Turkish Airlines via Istanbul, Emirates via Dubai and Qatar Airways via Doha also sell the route but none of them appeared among the cheapest fares when we checked.
Which airport do I fly into in Seoul?
You fly into Incheon International (ICN), Seoul’s main international gateway, about 50 km west of the city. The older Gimpo (GMP) airport is closer to the centre but handles mostly domestic and a few short regional routes, so intercontinental arrivals from Brussels use Incheon.
How far in advance should I book Brussels to Seoul flights?
Aim to book 2 to 4 months ahead. Long-haul fares to Seoul tend to rise as departure approaches, especially around cherry-blossom season, the autumn foliage weeks and the Christmas holidays, so booking early almost always wins on both price and connection quality.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than Friday–Sunday, and flying out and back on weekdays can save €40–€100 on a long-haul return. Being flexible by a day or two is one of the easiest ways to cut the fare.
