Cached-fare history: across 4 months, Oct is the cheapest for MEX → RIO. Best time to be there: Apr–Jun · Sep–Oct.
Fares on this route stay within about $73 across the 4 months we track — season matters less here than timing the drop. The cheapest itinerary we are tracking makes one stop and takes about 13 hours outbound, on a 7-night trip — ticketed under LATAM, which on a connecting fare need not operate every leg. At $685 for 7,683 km each way, that works out to about $45 per 1,000 km flown. That is about the $44 typical of long-haul fares here. Across the 22 departure cities we track at a similar distance from Rio de Janeiro, this fare ranks 7th — 56% above the $439 from Boston. That puts it in the cheaper half of the 23 routes of similar length we watch out of Mexico City, where the middle fare is $1,042.

MEX → RIO, answered.
Is $685 a good price for Mexico City to Rio de Janeiro?
Only slightly. The seasonal median is around $755 round-trip and this fare is 9% under it, about $70. 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 Mexico City to Rio de Janeiro?
Across 4 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Rio de Janeiro are Apr–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book MEX → Rio de Janeiro?
We do not publish a number for this, because we cannot measure it yet.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, 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 Mexico City to Rio de Janeiro?
The current cheapest fares involve a connection, ticketed under LATAM. 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.
