Cached-fare history: across 6 months, Jan is the cheapest for SEL → KUL. Best time to be there: May–Jul.
Fares bottom out in January around $252 and peak in November near $312 — a $60 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8.5 hours outbound, on a 14-night trip — ticketed under Shandong Airlines, which on a connecting fare need not operate every leg. At $252 for 4,614 km each way, that works out to about $27 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. Across the 6 departure cities we track at a similar distance from Kuala Lumpur, this fare ranks 2nd — 30% above the $194 from Shanghai. That puts it in the cheaper half of the 8 routes of similar length we watch out of Seoul, where the middle fare is $252.

SEL → KUL, answered.
Is $252 a good price for Seoul to Kuala Lumpur?
Only slightly. The seasonal median is around $290 round-trip and this fare is 13% under it, about $38. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Seoul to Kuala Lumpur?
Across 6 months of cached-fare history, Jan comes out cheapest on this route. The best months to actually be in Kuala Lumpur are May–Jul — when those overlap, that's your window.
How far in advance should I book SEL → Kuala Lumpur?
We do not publish a number for this, because we cannot measure it yet.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, Jan comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Seoul to Kuala Lumpur?
The current cheapest fares involve a connection, ticketed under Shandong Airlines. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). 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.
