Cached-fare history: across 4 months, Sep is the cheapest for SAO → MEX. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in September around $565 and peak in October near $760 — a $195 spread across the 4 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 $565 for 7,431 km each way, that works out to about $38 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Of the 9 departure cities we track at a similar distance from Mexico City, this is the cheapest right now — 20% under the next one, Lisbon. It is also the 2nd cheapest of the 19 routes of similar length we watch out of São Paulo.

SAO → MEX, answered.
Is $565 a good price for São Paulo to Mexico City?
Only slightly. The seasonal median is around $590 round-trip and this fare is 4% under it, about $25. 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 São Paulo to Mexico City?
Across 4 months of cached-fare history, Sep 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 SAO → 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We do not publish a number for this, because we cannot measure it yet.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 4 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from São Paulo to Mexico City?
The current cheapest fares involve a connection, ticketed under Copa Airlines. 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.
