Quick Take

  • Cheapest time to fly to Mexico City: late January–March, May (some weeks), September, and early December
  • Most expensive time to fly to Mexico City: March–April (spring break/Easter timing), June–August, and late December–early January

Cheapest Time to Fly to Mexico City

Lower prices usually show up right after holiday travel ends and again when summer demand fades.

Late January to March (post-holiday deal season)

Once the New Year rush is over, fares often cool down. This is one of the most reliable windows for cheaper flights into Mexico City (MEX).

Money-saving tip: Midweek departures: Tuesday–Thursday flights often price better than weekend-heavy dates.
Heads-up: Spring break creep: some March weeks climb fast if they overlap with school breaks.

May (deal-friendly weeks before summer ramps up)

May can have solid pricing—especially if you avoid holiday weekends and don’t travel right as summer demand starts building.

Money-saving tip: Target mid-month: the second and third weeks of May often have better odds than late May.
Heads-up: Weekend premiums: Friday departures and Sunday returns commonly price higher.

September (post-summer cooldown)

After summer travel fades, September often brings a nice dip in airfare. It’s also a month where small date shifts can make a big difference.

Money-saving tip: Date-shift test: compare leaving a day earlier vs. later—prices can swing quickly.
Heads-up: Holiday weekends: if a long weekend pops up, that can override the “cheap month” effect.

Early December (pre-holiday lull)

Early December often has better pricing before the year-end rush hits. It’s a great window if you want decent deal odds without waiting until deep winter.

Money-saving tip: Return before mid-December: it can keep you out of the holiday surge.
Heads-up: Pricing flips fast: once holiday travel starts, the deals disappear quickly.

Most Expensive Time to Fly to Mexico City

Mexico City gets pricey when US travel demand stacks up—especially around breaks, summer dates, and the holidays.

March to April (spring break and Easter timing)

This is one of the most common price-spike periods. Routes fill quickly when travelers plan warm-weather getaways.

Peak within peak: Thursday–Sunday travel patterns during school break weeks.

June to August (summer travel)

Summer often has a higher price floor. Even “good” fares tend to be higher than the cheaper months.

Peak within peak: Late June through early August is usually the toughest stretch.

Late December to Early January (holiday travel)

Year-end travel can push prices to the highest levels of the year—especially if you’re flying on peak days.

Peak within peak: Late-December departures + early-January returns.


Booking Window for Cheap Fares to Mexico City

Because it’s a popular route, good fares can vanish quickly—especially for long weekends.

  • Low/shoulder seasons: start tracking 1–3 months ahead
  • Peak seasons (spring break, summer, late December): start tracking 3–6+ months ahead

Extra tip: Compare airports: Mexico City has MEX (AICM) and NLU (Felipe Ángeles). One can be cheaper than the other depending on your airline and dates—so it’s worth checking both.
