Cached-fare history: across 4 months, Oct is the cheapest for SEL → MEX. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in October around $957 and peak in December near $1,335 — a $378 spread across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 15.5 hours outbound, on a 19-night trip — ticketed under Air Premia, which on a connecting fare need not operate every leg. At $957 for 12,052 km each way, that works out to about $40 per 1,000 km flown. That is about the $40 typical of ultra-long-haul fares here. Across the 26 departure cities we track at a similar distance from Mexico City, this fare ranks 15th — 23% above the $776 from Madrid. That puts it in the cheaper half of the 25 routes of similar length we watch out of Seoul, where the middle fare is $996.

SEL → MEX, answered.
Is $957 a good price for Seoul to Mexico City?
Only slightly. The seasonal median is around $1,160 round-trip and this fare is 18% under it, about $203. 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 Mexico City?
Across 4 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Mexico City are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book SEL → Mexico City?
We do not publish a number for this, because we cannot measure it yet.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 4 months of cached fares, Oct 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 Mexico City?
The current cheapest fares involve a connection, ticketed under Air Premia. 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.
