Fares bottom out in November around $1,158 and peak in June near $1,696, 46% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 15 hours outbound, on a 12-night trip — ticketed under ZIPAIR, which on a connecting fare need not operate every leg. At $1,158 for 11,311 km each way, that works out to about $51 per 1,000 km flown. That is above the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 24 departure cities we track at a similar distance from Mexico City, this fare ranks 20th — 56% above the $743 from Madrid. For context, the middle fare among the 46 routes of similar length we watch out of Tokyo is $1,015. The best time to be in Mexico City: Mar–May · Oct–Nov.

Route facts
Good to know
Only slightly. The seasonal median is around $1,405 round-trip and this fare is 18% 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.
Across 6 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.
We do not publish a number for this, because we cannot measure it yet.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.
The current cheapest fares involve a connection, ticketed under ZIPAIR. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
