When this route gets cheap.
Fares bottom out in October around $542 and peak in December near $764, 41% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 10.5 hours outbound, on a 7-night trip — ticketed under Copa Airlines, which on a connecting fare need not operate every leg. At $542 for 7,431 km each way, that works out to about $36 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Of the 12 departure cities we track at a similar distance from São Paulo, this is the cheapest right now — though Miami is within a few dollars. It is also the cheapest of the 17 routes of similar length we watch out of Mexico City. The best time to be in São Paulo: Mar–May · Sep–Nov.

Good to know
MEX → SAO, answered.
Is $542 a good price for Mexico City to São Paulo?
Yes — the seasonal median for this route is around $680 round-trip. At $542 you're 20% below that, which we rate good for this route.
What is the cheapest month to fly from Mexico City to São Paulo?
Across 5 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in São Paulo are Mar–May · Sep–Nov — when those overlap, that's your window.
How far in advance should I book MEX → São Paulo?
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Mexico City to São Paulo?
The current cheapest fares involve a connection, ticketed under Copa Airlines. 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.
