Air passenger rights in Mexico: what US flyers are owed

A canceled flight out of Cancún or a long delay on the way home from Mexico City doesn't leave you empty-handed. Mexico's Ley de Aviación Civil (Civil Aviation Law) sets out exactly what the airline has to give you, and the cash compensation is calculated as a share of your fare rather than a flat figure.

For travelers used to domestic flying, Mexican rules work in a way that's worth knowing about. US federal regulations make sure you get a refund when a flight is canceled or runs badly late, which covers the money you already spent. Mexican law goes a step further and can also put some cash in your pocket for the disruption itself, so it's worth understanding what you're entitled to before you write off a delayed trip.

AirHelp doesn't file claims under Mexican law; that process runs through PROFECO, the country's consumer protection agency. What we can do is check whether a second set of rules applies to your trip. If a European airline operated your flight, or your itinerary connected through Europe, EC 261 may cover you for a fixed amount of up to $650 per person. Running your flight through our checker costs nothing.

The Ley de Aviación Civil is Mexico's federal aviation law, and it's the rulebook that kicks in whenever a flight to, from, or within Mexico doesn't go as planned. Coverage is broad: it reaches every flight on those routes, whether you're booked with a Mexican airline like Aeroméxico, Volaris, or Viva Aerobus, or with a US carrier such as American, United, or Delta flying in or out of a Mexican airport. Keeping airlines in line falls to PROFECO, the federal consumer protection agency, which takes up the case when a carrier won't play by the rules.

What catches most US flyers off guard is how the payout is figured. There's no fixed schedule of amounts here. Instead, qualifying disruptions earn you at least 25% of your ticket price in cash, paid on top of any refund or rerouting you're due. Because it's a percentage, the number tracks your fare, so a passenger who paid full price for a last-minute seat can walk away with far more than the neighbor who booked months ahead on a discount fare.

The Ley de Aviación Civil ties your compensation to your fare, not to a fixed scale, so the figure depends on what you paid. It becomes payable once a flight is substantially delayed, canceled, or overbooked, as long as the airline is the one at fault. Here's how the entitlements break down.

Once your claim is in, the airline has 10 days to pay the 25%. Anything covering food, drinks, and a place to stay has to be provided then and there, while the disruption is still going on.

These protections cover any flight that falls under Mexican law, from a short domestic hop between Mexico City and Cancún to the leg carrying you home on a Mexican airline.

Delays

The longer you're held up, the more the airline has to do for you.

• At the 1-to-2-hour mark, the bare minimum is food and drinks, a voucher toward a later flight on the same route, or some combination of the two, with the exact mix down to the carrier's own policy.

• Cross into the 2-to-4-hour band and the same holds, except any voucher now has to be worth at least 7.5% of your ticket price.

• Once the delay runs past 4 hours, you get the same set of choices as a canceled flight, covered just below: a refund, a seat on the next available flight, or a reschedule for later. Take the refund or the reschedule and the 25% cash payment applies.

No matter how long the delay runs, the airline has to give you free access to phone calls and emails for the entire time you're kept waiting.

Cancellations and denied boarding (overbooking)

When the airline scraps your flight for a reason it controls, or turns you away because the flight was oversold, the choice is yours among three options:

• a refund, plus at least 25% of the ticket price in cash on top

• rerouting on the next available flight, with meals, a hotel for any overnight wait, and a ride to and from the airport

• rebooking for a later date that suits you, with the same 25% in cash

Overbooking carries one extra wrinkle. Before anyone gets bumped against their will, the airline has to ask for volunteers willing to give up a seat in exchange for perks. Only when too few step forward does involuntary denied boarding come into play, and at that point the 25% is owed across all three options, rerouting included.

When the airline is off the hook

If a disruption stems from an extraordinary circumstance outside the airline's control, the carrier owes you nothing, neither the cash compensation nor the food and lodging. The usual suspects are severe weather, political unrest, security threats, and air traffic control restrictions.

Claiming under the Ley de Aviación Civil comes down to three stages. The clock gives you one year to lodge a complaint, a window set by article 14 of Mexico's Federal Consumer Protection Law.

1. Start with the airline. Most carriers take complaints through a form on their website, and some will handle them at an airport desk too. Lay out your booking details and what happened, attach receipts for anything you had to pay out of pocket, and hang on to a record of every exchange: emails, reference numbers, screenshots.

2. Bring in PROFECO. If the airline stonewalls you or won't pay what it owes, Mexico's consumer protection agency is your next move. PROFECO runs free online conciliation through two platforms, Concilianet and Conciliaexprés, which together handle most of the bigger airlines flying in Mexico. If yours isn't on either one, you can file in person at an ODECO (PROFECO's local office), or reach the agency by phone or through its consumer helpline.

3. Go to court if conciliation stalls. When PROFECO conciliation doesn't settle things, you've still got room to move, including taking the dispute to a Mexican civil court.

Worth having ready before you start: your e-ticket or boarding pass, proof that the disruption happened (airline emails or screenshots usually do the trick), and receipts for any money you laid out.

Could AirHelp step in under a different law?

AirHelp doesn't take on claims under the Ley de Aviación Civil; those belong with PROFECO. But two other situations are worth a look. If your bags were lost, damaged, or delayed on an international flight, the Montreal Convention can cover you for up to $1,950, and AirHelp+ members can pass that claim to us. And if a European airline operated your flight, or you connected through Europe, EC 261 may apply on top of Mexican law, often for more than the 25%. It's free to check which rules fit your trip.
