The cheapest times to fly to Mexico

Cheapest: late spring through summer and the fall shoulder season - outside US holidays and spring break. For beach destinations, the summer and fall low season brings the best fares (with a small trade-off in heat and rain). Most expensive: spring break (March), Christmas, and New Year, when beach demand spikes hard. City destinations like Mexico City stay cheap nearly year-round. Combine your dates with the cheapest days to fly for more savings.

How far ahead to book

Mexico is shorter-haul, so the domestic-style window applies: 1-3 months ahead is the sweet spot for most routes, a bit earlier for beach destinations over peak weeks. The reasoning is in our when to book flights guide.
