01Fare seasonality

When this route gets cheap.

Best time to be in São Paulo: Mar–May · Sep–Nov. Fare history for this route is still thin, so we make no seasonal call yet.

The cheapest itinerary we are tracking makes one stop and takes about 11 hours outbound, on a 6-night trip — ticketed under Avianca, which on a connecting fare need not operate every leg. At $723 for 7,431 km each way, that works out to about $49 per 1,000 km flown. That is about the $44 typical of long-haul fares here. Across the 12 departure cities we track at a similar distance from São Paulo, this fare ranks 6th — 2.0× the $357 we hold from Boston. That puts it in the cheaper half of the 16 routes of similar length we watch out of Mexico City, where the middle fare is $1,050. We have 3 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

The median cached fare across this calendar is 24% higher than when tracking began on Aug 8 — $633 then versus $787 now, across 5 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $596, on Oct 9.

These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

02Good to know

MEX → SAO, answered.

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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.

Are there nonstop flights from Mexico City to São Paulo?

The current cheapest fares involve a connection, ticketed under Avianca. 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.
