Fare seasonality

When this route gets cheap.

Fares bottom out in November around $451 and peak in May near $827, 83% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 11.5 hours outbound, on a 6-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $476 for 8,705 km each way, that works out to about $27 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 27 departure cities we track at a similar distance from Seoul, this fare ranks 3rd — 4% above the $458 from Istanbul. That puts it in the cheaper half of the 36 routes of similar length we watch out of Brussels, where the middle fare is $719. The best time to be in Seoul: Apr–May · Sep–Oct.

Good to know

BRU → SEL, answered.

Is $476 a good price for Brussels to Seoul?

Yes — the seasonal median for this route is around $800 round-trip. At $476 you're 41% below that, which we rate rare for this route.

What is the cheapest month to fly from Brussels to Seoul?

Across 6 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Seoul are Apr–May · Sep–Oct — when those overlap, that's your window.

How far in advance should I book BRU → Seoul?

We do not publish a number for this, because we cannot measure it yet.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 6 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.

Are there nonstop flights from Brussels to Seoul?

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.

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.
