Cached-fare history: across 4 months, Oct is the cheapest for MEX → SEL. Best time to be there: Apr–May · Sep–Oct.
Fares bottom out in October around $1,084 and peak in May near $1,358 — a $274 spread across the 4 months we track. The cheapest itinerary we are tracking makes 3 stops and takes about 20.5 hours outbound, on a 5-night trip — ticketed under Flair, which on a connecting fare need not operate every leg. At $1,084 for 12,052 km each way, that works out to about $45 per 1,000 km flown. That is about the $40 typical of ultra-long-haul fares here. Across the 13 departure cities we track at a similar distance from Seoul, this fare ranks 11th — 2.1× the $512 we hold from Los Angeles. That puts it in the cheaper half of the 39 routes of similar length we watch out of Mexico City, where the middle fare is $1,115.

MEX → SEL, answered.
Is $1,084 a good price for Mexico City to Seoul?
Only slightly. The seasonal median is around $1,280 round-trip and this fare is 15% under it, about $196. 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 Mexico City to Seoul?
Across 4 months of cached-fare history, Oct 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 MEX → 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We do not publish a number for this, because we cannot measure it yet.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 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 Mexico City to Seoul?
The current cheapest fares involve a connection, ticketed under Flair. 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.
