When this route gets cheap.
Fares bottom out in November around $1,167 and peak in May near $1,445, 24% dearer, across the 7 months we track. The cheapest itinerary we are tracking makes one stop and takes about 20.5 hours outbound, on a 7-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $1,167 for 12,052 km each way, that works out to about $48 per 1,000 km flown. That is about the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 25 departure cities we track at a similar distance from Mexico City, this fare ranks 20th — 57% above the $743 from Madrid. That puts it in the cheaper half of the 24 routes of similar length we watch out of Seoul, where the middle fare is $1,167. The best time to be in Mexico City: Mar–May · Oct–Nov.

Good to know
SEL → MEX, answered.
Is $1,167 a good price for Seoul to Mexico City?
Only slightly. The seasonal median is around $1,215 round-trip and this fare is 4% under it. 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 7 months of cached-fare history, Nov 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We do not publish a number for this, because we cannot measure it yet.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 7 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 Seoul to Mexico City?
The current cheapest fares involve a connection, ticketed under Korean Air. 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.
