Cached-fare history: across 5 months, Oct is the cheapest for LON → MEX. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in October around $819 and peak in January near $1,073 — a $254 spread across the 5 months we track. The cheapest itinerary we are tracking makes 3 stops and takes about 15.5 hours outbound, on a 10-night trip — ticketed under Ryanair, which on a connecting fare need not operate every leg. At $819 for 8,929 km each way, that works out to about $46 per 1,000 km flown. That is about the $44 typical of long-haul fares here. Across the 19 departure cities we track at a similar distance from Mexico City, this fare ranks 7th — 45% above the $565 from São Paulo. For context, the middle fare among the 40 routes of similar length we watch out of London is $661.

LON → MEX, answered.
Is $819 a good price for London to Mexico City?
Only slightly. The seasonal median is around $950 round-trip and this fare is 14% under it, about $131. 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 London to Mexico City?
Across 5 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 LON → 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We do not publish a number for this, because we cannot measure it yet.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 5 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 London to Mexico City?
The current cheapest fares involve a connection, ticketed under Ryanair. 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.
