Flights to Mexico in 2027: How to Fly South for Less

Mexico is close. That doesn't mean the flight is always cheap.

What you pay comes down to three choices: when you go, when you book, and where you land. Get them right and the ticket prices shrink. Get them wrong and the flights eat your vacation fund.

We went through RatePunk's fare data to sort out all three, so you can save your pesos for the beach, tacos, and a second margarita.

What a Good Fare Looks Like

The fastest way to spot a deal is to know the going rate. So before you start searching, here's the number to keep in your back pocket.

We count a fare as good when it beats nine in ten of the fares we tracked for that trip. You probably won't see one every time you search, which is exactly why it pays to research when to book.

Here's what a good round trip to Cancún looked like from some of the bigger U.S. airports. If yours isn't listed, go by the nearest big one.

• Philadelphia, Atlanta, Chicago, and Denver: about $200
• Houston: $205
• Dallas: $210
• Los Angeles: $255
• Miami: $265
• New York and Boston: $295
• San Francisco: $340

The season matters as much as the airport. A deal in February and a deal in July are two very different numbers, so this table shows the bar for each month.

The Cheapest Months to Fly

January and February are the cheapest months for U.S. travelers flying to Mexico. Fares in both came in below the year's usual fare, which is the middle price of everything we tracked.

• January: 8.5% cheaper
• February: 8.3% cheaper

Most of the rest of the year sits near the middle. March, April, September, October, and November each landed close to the usual fare, a little over or a little under, so any of them works as a backup. Prices only really climb in two stretches: summer, with July 33% above the usual fare, and the holidays, with December 23% above it.

Bottom line: Lock in the month you’ll travel before anything else. The month makes the biggest price difference.

Round-trip fares from the U.S. to Mexico by departure month, compared with the usual fare for the year. January was 8.5% below usual and February 8.3% below, followed by March at 1.9% below, September at 1.4%, and October at 0.5%. April and November were 0.7% above usual, May 10%, August 21%, and December 23%. June was 29% above and July was highest at 33% above.

What Holidays Do to Fares

Christmas and New Year are when flights to Mexico get really expensive. Fares over the holidays ran 63% higher than on other December and January dates. Easter week carries a smaller premium, but it's still 23% above other dates in March and April.

And it's not just the price. The TSA expects the weeks around Christmas and New Year to be among its busiest of the year, so plan for long security lines on top of the higher fare.

Spring break, on the other hand, is a pleasant surprise. Flights during the main spring break weeks in March cost 8.3% more than in late February and 1.7% less than in mid-April.

U.S. long weekends are a mixed bag. Here's how each one stacked up against the weeks on either side of it:

• Presidents' Day weekend: 17% to 18% more
• Thanksgiving week: 17% to 18% more
• Memorial Day weekend: 17% more than the week before, 1.3% more than the week after
• Fourth of July: 7.7% cheaper than the week before, 2% pricier than the week after

The Fourth of July is the long weekend to aim for. Fares that week were lower than the week before, so it's a smart time to head south.

If your holiday dates have some wiggle room, shift your trip by a week.

Flying in Summer

Summer is when flights to Mexico cost the most, and August is the least painful of the three summer months. Here's how each one compared with the year's usual fare:

• June: 29% above
• July: 33% above
• August: 21% above

July tops the whole calendar for price. If school or work holidays lock you into summer, August is your best bet.

Can you shift your trip by a few weeks? Leaving just before or after summer saves even more. May came in 10% above the usual fare, and September landed 1.4% below it.

When to Book

The best window for booking flights to Mexico is three weeks to two months before departure. Leave it to the last few days and you'll pay a lot more, but booking really early doesn't help either.

Here's how fares at each booking distance compared with the usual fare for the same route and month:

• Last 3 days: 25% more
• 4 to 7 days out: 16% more
• 1 to 2 weeks out: 4.5% more
• 2 to 3 weeks out: 0.4% more
• 3 weeks to 2 months out: 0.4% to 0.6% less
• 2 to 3 months out: 1.7% more
• 3 to 4 months out: 13% more
• 4 to 6 months out: 28% more
• 6 to 10 months out: 97% more (fewer routes available to price)

That's a tighter window than many people expect. There's no prize for booking half a year out, so choose your dates and start watching prices about two months ahead.

Booking at least a week out comes with a bonus, too. The U.S. Department of Transportation requires airlines to either let you cancel within 24 hours for a full refund or hold your fare for 24 hours at no cost, as long as you book seven or more days before you fly. If the price drops the morning after you book, you've got room to change your mind.

Round-trip fares to Mexico by how far ahead they were seen, compared with the usual fare for the same route and month. Fares seen one to one and a half months out were cheapest at 0.6% below usual, followed by three to four weeks at 0.5% below and one and a half to two months at 0.4% below. Two to three weeks out was 0.4% above usual, two to three months 1.7%, one to two weeks 4.5%, three to four months 13%, four to seven days 16%, zero to three days 25%, and four to six months 28%. Fares seen six to ten months out were highest at 97% above usual.

Choosing an Arrival City

Guadalajara and Cancún are the cheapest big cities to fly into. Guadalajara led the way at 9.7% under the usual fare to Mexico, Cancún came in just behind it, and Mexico City landed close to the middle.

The Pacific beach towns cost a bit more to reach directly:

• Puerto Vallarta: 3.8% above the usual fare
• Los Cabos: 6.9% above the usual fare

If any beach will do, Cancún gets you the most sand for your money. And for a food-and-culture city break, Guadalajara is easy to overlook and cheaper to reach than Mexico City.

One-Way Tickets vs Round Trip

Here's a Mexico twist: two one-way tickets can cost about the same as a round trip. It mostly comes down to which direction you fly.

Landing in Cancún and leaving from Mexico City on separate one-way tickets was the pricey way to do it, about $55 (or 13%) on top of a round trip into Cancún.

Reverse the route, or start on the Pacific coast, and the extra cost mostly vanishes. Compared with a round trip into the first city:

• Into Mexico City, home from Cancún: 0.6% more
• Into Los Cabos, home from Mexico City: 1.7% less
• Into Puerto Vallarta, home from Mexico City: 3.3% less

Planning a beach-plus-city trip? Check prices in both directions before you commit. Multi-city tickets, where an airline books the whole route as one trip, are worth a look too.

Choosing a Departure Airport

Texas and California have the edge when it comes to flights to Mexico. Counting every Mexican city it flies to, Houston was the cheapest big U.S. city to fly from, at 37% below the usual fare to Mexico.

Several other big cities also beat the usual fare to Mexico by a wide margin:

• Los Angeles: 29% cheaper
• Miami: 28% cheaper
• San Antonio: 25% cheaper
• Dallas: 23% cheaper
• Chicago: 16% cheaper
• Denver: 13% cheaper

Live near Houston? Lucky you. Houston to Cancún tied for the cheapest of the busiest routes we tracked, at 46% below the usual fare to Mexico. The chart below shows the rest of the top ten.

Your home airport can even flip which city is cheaper to land in. Out of Los Angeles, Mexico City came in 14% cheaper than Cancún. Out of New York, it was the other way around, with Cancún 17% cheaper. So price both before you settle on one.

Usual round-trip fares on the 10 cheapest of the 30 busiest U.S.-to-Mexico city pairs. Houston to Cancún, Los Angeles to Guadalajara, and Houston to Mexico City were each about $230, Philadelphia to Cancún about $240, Dallas to Mexico City about $260, Chicago to Mexico City about $265, Dallas to Cancún about $275, Denver to Mexico City about $280, Los Angeles to Mexico City about $285, and Atlanta to Cancún about $290.

Nonstop or Connecting Flights

On a short trip like this, going nonstop doesn't cost much extra. Nonstop flights to Mexico usually ran about $25 more than connecting ones for the same route on the same dates, and 22% of the time they were actually the cheaper option.

$25 is the middle across every route we compared, so individual cities land on either side of it:

• Los Cabos: about $20 more
• Cancún: about $30 more
• Mexico City: about $35 more
• Puerto Vallarta: about $35 more

For that small extra, you skip the layover and start your vacation sooner.

Frequently Asked Questions

What is the cheapest month to fly to Mexico?

January edges out February as the cheapest month for flights to Mexico. January fares sat 8.5% below the year's usual fare, with February at 8.3% below.

At the other end, July was the priciest month, at 33% above the usual fare.

What day of the week is cheapest to fly to Mexico?

Counting the day your outbound flight leaves, Monday and Tuesday were the cheapest days to fly to Mexico, each 1.8% below the usual fare for the same route. Sunday came close at 1.6% below.

Thursday and Friday were the priciest days, at 2.8% and 3% above the usual fare. Those gaps are tiny next to the swing between months, so choose your month first and your day second.

Which airlines have the cheapest flights to Mexico?

Mexico's budget airlines have a slight edge. Volaris and Viva Aerobus showed up a little more often among the cheapest fares on each route than among fares overall, so they're worth checking first.

Frontier landed on cheap fares about as often as it showed up overall. Aeroméxico went the other way, with fewer cheap fares than its share of all fares would suggest.

Does the length of your trip change the price of a flight to Mexico?

Not really. Whether you stay a few nights or a month, fares landed at the usual price for that route and month. Book the trip length you want.

What do U.S. citizens need to fly to Mexico?

The U.S. State Department says most U.S. tourists can visit Mexico without a visa for up to 180 days. You'll need a passport that's valid on the day you arrive, with one blank page for the entry stamp.

Mexico's digital migration form, the FMMd, no longer needs filling out before you fly. Mexico's immigration institute says air travelers download it after they land, by scanning the QR code at the immigration check.

Heading to Cancún or anywhere else in Quintana Roo? The state also charges foreign tourists a visitor contribution called Visitax, which you pay online through the state's official Visitax site.

How We Got These Numbers

We used round-trip economy fares between U.S. airports and Mexico that RatePunk saw in flight searches, mostly three weeks to four months before departure. The usual fare is the median, so half the fares were cheaper and half cost more. Entry rules come from the U.S. State Department and Mexico's immigration institute. These are prices shown in searches, not prices anyone paid.
