Cheap Flights to Mexico in 2027: 11 Sites and the Busiest Airports

Cancún and Mexico City handle most international flights to Mexico, but Guadalajara, Monterrey, Puerto Vallarta, and Los Cabos take them too, and their prices rarely match on the same dates. Pricing several of those airports and buying one to two months out usually saves the most.

Whether you’re drawn to the sun-soaked coastlines or the cultural gems inland, comparing cheap flights to Mexico across airports and dates is where the savings start.

Why Mexico

Mexico remains one of the most popular destinations worldwide, with over 180 million passengers passing through its airports each year. Whether you’re heading to Cancún’s beaches, exploring Mexico City’s museums, or relaxing in Tulum, there’s a flight, and a deal, out there for you.

Tips for Booking Cheap Mexico Flights

• Set up deal alerts. Momondo and Skyscanner send price alerts for the Mexico routes you save.
• Be flexible. Try different dates and nearby airports for the best prices.
• Book in advance. Aim for one to two months before your trip for international flights to Mexico.
• Check baggage policies. Low-cost carriers may offer great fares but charge extra for bags and seat selection.
• Compare more than the obvious airport. Mexico has several international gateways, and on the same dates they rarely price the same.
• Travel off-peak. Avoid major holidays and school vacation weeks where you can.

The 11 Best Websites Compared

1. Google Flights

A leading metasearch engine that aggregates flight data from hundreds of airlines and online travel agents behind a fast, intuitive interface. It does not sell tickets; it redirects you to the airline or agent to book. It includes low-cost carriers like VivaAerobus and Volaris, which matters a great deal on Mexican routes, and its Explore tool compares dates and alternative gateways.

Pros

• Price prediction tool

Best for: flexible travelers, price trackers, cross-border planners.

2. Expedia

A major online travel agent where you book flights, hotels, and packages directly, earning One Key Rewards points that stack with airline miles. Its inventory includes Aeroméxico, Volaris, and VivaAerobus. Flexible date searches, budget filters, and no-change-fee options suit cautious travelers, with 24/7 support behind them.

Cons

3. Kayak

A metasearch engine that compares prices across airlines and agents, then redirects you elsewhere to book. Hacker Fares combine one-way tickets from two different airlines, such as Aeroméxico out and Delta back, which often beats a single-carrier return on a Mexico route. PriceCheck verifies a deal against an itinerary screenshot.

Pros

4. Momondo

A Booking Holdings metasearch engine with an intuitive interface and unusually wide coverage, including budget carriers like Volaris and VivaAerobus on Mexican routes. Mix & Match combines one-way tickets for savings, though the booking can split across two sites. Visual price trend graphs, filters down to aircraft type, and CO2 emission sorting cover a lot of ground.

Pros

• Visual price graphs
• Mix & Match fares
• Extensive filters, including aircraft type
• Budget carrier coverage
• CO2 emission sorting

Cons

• Mix & Match splits your booking in two
• Can miss some regional carriers

5. Skiplagged

Skiplagged specializes in hidden-city ticketing: booking a flight that stops in Mexico on the way somewhere else, then simply not taking the final leg. On cross-border and international routes this can cut the fare sharply. It is also the riskiest option here, and worth understanding fully before you use it.

Pros

• Hidden-city fares no conventional search will show you
• Simple interface
• Good for one-way or last-minute trips

Cons

• Airlines prohibit hidden-city ticketing in their conditions of carriage
• You cannot check a bag, since it travels to the ticketed final destination
• Skipping a segment normally cancels the rest of the itinerary, including your return
• Frequent flyer accounts have been closed over it
• Limited support if something goes wrong

Best for: risk-tolerant travelers, one-way flyers, and lowest-price seekers.

6. Skyscanner

A top metasearch engine comparing prices across airlines and agents, including Aeroméxico, Volaris, and VivaAerobus. Its Everywhere search shows the cheapest destinations from your departure city, which suits a flexible traveler. Calendar views highlight low-fare dates and price alerts track the drops.

Pros

• Everywhere search for open-ended trips
• Calendar view for the cheapest dates
• Price alerts and strong filters
• Budget carrier coverage
• Well-built app

Cons

• Can miss some regional carriers
• Redirects may add fees
• Prices can change on the booking site

Best for: flexible travelers, budget seekers, and cross-border flyers.

7. Cheapflights

A Booking Holdings metasearch engine built around visual tools: price calendars and fare trend charts. It includes budget airlines like Volaris and VivaAerobus, and its Smart Value algorithm balances cost against convenience, so a slightly pricier fare with a shorter layover can rank higher. Filters cover layover cities, alliances, and fare policies.

Pros

• Price calendars and fare charts
• Smart Value ranking that weighs cost against convenience
• Budget airline coverage
• Strong filters
• Easy interface

Cons

• Can miss ultra-low-cost carriers
• Third-party redirects
• Limited support, as a metasearch engine

Best for: visual comparers, deal hunters, and budget carrier seekers.

8. Orbitz

An online travel agent offering direct booking of flights, hotels, and packages, with Orbitz Rewards earning Orbucks that you can spend on later travel. Its inventory includes Aeroméxico and Volaris, and a price guarantee refunds the difference if a cheaper fare appears after you book.

Pros

• Orbitz Rewards and Orbucks
• Direct booking with real support
• Price guarantee
• Flexible date and fare policy filters
• Bundling deals

Cons

• Possible booking fees
• Not a metasearch engine, so it can miss deals
• Prices can exceed booking direct with the airline

Best for: Orbitz Rewards members, bundlers, and support seekers.

9. Travelocity

An Expedia Group agent focused on direct bookings, with a Price Match Guarantee that refunds the difference on a lower fare found within 24 hours. The interface is straightforward, with flexible date searches and filters for budget or changeable tickets, and it bundles well for routes to Cancún or Puerto Vallarta.

Pros

• Price Match Guarantee
• Direct booking with support
• Flexible date and budget filters
• Strong on US to Mexico routes
• Bundling deals

Cons

• Potential booking fees
• Limited budget carrier coverage
• Less comprehensive than a metasearch engine

Best for: cross-border travelers, bundlers, and price guarantee seekers.

10. Priceline

An online travel agent best known for Express Deals, which discount a fare in exchange for hiding the airline and exact times until after you book. Standard searches with flexible dates sit alongside them, its inventory includes Aeroméxico, and a VIP programme adds further discounts as you book more.

Pros

• Express Deals for lower fares
• Flexible dates and filters
• VIP programme discounts
• Bundling options
• Reliable support

Cons

• Express Deals hide the details until after purchase
• Some booking fees
• Not a metasearch engine, so it can miss deals

Best for: deal seekers comfortable with uncertainty, and bundlers.

11. RatePunk

RatePunk keeps track of what flights from your home airport usually cost, and we alert you when one drops below that price. A deal to Cancún, Mexico City, or another Mexican city lands in the RatePunk app, on the web dashboard, and in deal emails. Our AI Deal Score marks each deal out of 100, and about 150 million flight prices go through our checks daily. We don’t sell the ticket, so you buy it from the airline or a travel site.

Pros

• Mexico deals without running searches
• A score out of 100 for every Mexico deal
• App filters for destination and dates
• See the usual price beside the deal

Cons

• Deals require a paid membership
• Bought through the airline or a booking site
• A single home airport for alerts

Best for: flexible travelers who could fly into more than one Mexican city.

The Bottom Line

No single website is cheapest on every route into Mexico. The metasearch engines cast the widest net and are where a search should start, especially because Volaris and VivaAerobus carry so much of the traffic and not every site lists them. The online travel agents earn their keep when you want one itinerary, real support, and rewards points. Skiplagged is a category of its own, with real savings and real consequences.

Mexico has more usable international gateways than most countries, and that is the lever worth pulling. Cancún and Mexico City are the obvious choices, but Monterrey, Guadalajara, Puerto Vallarta, and Los Cabos are all real options, and on the same dates they rarely price the same. Book one to two months out, stay flexible on dates, check the final price with bags included, and then let an alert watch the route instead of searching it yourself.

FAQ

How far in advance should I book my flight to Mexico?

For the best prices, book roughly one to two months before departure. Booking much later than that usually costs more, and booking very far ahead rarely helps on these routes.

Which airports in Mexico are best for cheap flights?

It depends on where you are flying from, and the answer is often not the obvious one. Cancún and Mexico City get the most traffic, but Monterrey, Guadalajara, Puerto Vallarta, and Los Cabos are all worth pricing on the same dates before you decide. Comparing several gateways is usually worth more than picking the right week.

Which Website Should You Use for Flights to Mexico?

Which site to use depends on the trip:

• Comparing Mexican airports — Google Flights and Momondo include Volaris and VivaAerobus alongside the bigger airlines.
• A flight and hotel package — Expedia bundles the two and adds One Key Rewards points.
• A cheaper fare without knowing the airline first — With Express Deals on Priceline, you see the airline after you book.
• A Mexico deal you didn’t search for — When a Cancún or Mexico City flight from your home airport is cheaper than normal, it arrives as a RatePunk deal.
