Aeromexico Pet Policy Guide to Fly with Dogs or Cats 2026

The Aeromexico pet policy permits small pets in the aircraft cabin and offers options for larger animals via checked baggage or specialized cargo services. You must align your travel plans with these mandatory standards to ensure your pet boards the aircraft without incident.

The Aeromexico emotional support animal policy follows standard pet rules, meaning these animals no longer receive free service animal accommodations. Service dogs must undergo individual training to perform tasks for a person with a disability, a requirement that differs significantly from general pet travel protocols.

This article details the booking process, specific requirements for a pet in the cabin, associated travel fees, and international documentation mandates. You will find information regarding Aeromexico’s dog policy, including weight restrictions and prohibited breeds, to help you prepare your animal for the journey.

Booking a Flight Under the Aeromexico Pet Travel Policy

You must book the space for your pet simultaneously with your passenger ticket to ensure availability on your specific flight. Aeromexico limits the number of animals allowed on each aircraft, so contacting the airline to reserve this spot immediately after purchasing your own ticket prevents capacity issues. Failure to secure this reservation in advance may result in the refusal of your animal at the gate.

All pets must be at least 8 weeks old to qualify for transport on Aeromexico flights. You must ensure your animal is healthy enough for the journey and not undergoing any active veterinary treatment. Breastfeeding animals remain ineligible for travel, and you must verify that your pet meets all physical requirements before you complete your booking.

Passengers traveling with pets must check in at the airport counter in person to verify documentation and carrier compliance. You cannot complete the check-in process for a pet online or via mobile devices. This mandatory in-person verification ensures your pet’s carrier meets all safety specifications and your required health documentation remains accurate.^source

Aeromexico Pet in Cabin Policy

The Aeromexico pet in cabin policy allows small animals to travel in the aircraft cabin on flights lasting 6 hours or less. You must ensure the animal remains inside its carrier or container for the entire duration of the flight. This container must stay placed underneath the seat in front of you, as cabin storage regulations strictly prohibit placing carriers on empty passenger seats.

Only small dogs and cats are eligible to fly in the aircraft cabin. Each passenger may bring only 1 pet, and you must occupy a window seat, excluding rows identified as emergency exits or bulkhead seating. Animals must remain inside their carriers, and the consumption of food or liquids during the flight is prohibited.

The maximum weight allowed for a pet in the cabin is 20 lbs (9 kg), which includes the combined weight of the animal and the carrier. You must ensure your pet stays within these strict limits, as any animal exceeding this weight cannot travel in the cabin. Animals that are too heavy for cabin travel may be eligible for transport as checked baggage or via Aeromexico Cargo.^source

Cabin Carrier Requirements

• The carrier must not exceed dimensions of 16 inches by 12 inches by 8 inches (40 cm by 30 cm by 20 cm).^source
• Your container must be leak-proof and secure to prevent any accidents during the trip.
• The carrier must provide adequate ventilation for your pet to breathe comfortably.
• You must keep your pet inside the carrier for the entire duration of the flight.

Aeromexico Pet Fees for Cabin Travel

The costs for traveling with pets depend on your route and the season of travel. Domestic flights within Mexico range from $1,350 MXN to $1,700 MXN per flight segment. International flights incur fees between $162 USD and $168 USD based on your specific destination and seasonal demand. You should consult the airline directly to confirm the exact fee for your travel dates.

Route	Pet Fee	Notes
Domestic Mexico	$1,350 - $1,700 MXN	One-way fee
U.S./International	$162 - $168 USD	Varies by route
Oversized Cases	Varies	May require cargo

Aeromexico Dog Policy for Checked or Cargo Travel

Larger animals that cannot fit under the aircraft seat must travel as checked baggage or through Aeromexico Cargo services. You must verify that your dog is not a restricted breed and remains fit for travel in the cargo hold. Safety remains the priority for non-brachycephalic breeds, and all containers must allow the animal to stand, turn, and lie down freely.

International Rules Under Aeromexico Airlines Pet Policy

International travel requires strict adherence to both airline regulations and the specific import laws of your destination country. You should research quarantine requirements and entry mandates well in advance of your departure date. Proper documentation, including health certificates and vaccination records, is necessary to clear customs and ensure your pet’s entry.

Required Documents for International Pet Travel

Country Restrictions for Pets

Every destination country maintains distinct import regulations regarding the entry of live animals. Some nations require mandatory quarantine periods upon arrival, which can last several weeks. You must verify the specific requirements of your destination to avoid the detention or refusal of your pet at the border.

These restrictions may apply whether you are flying with a pet, emotional support animal, or psychiatric service dog. Even when a traveler carries supporting documentation such as a PSD letter, that documentation does not override customs regulations, vaccination rules, or quarantine laws imposed by the destination country.

You should distinguish between a household pet and an aeromexico service dog, as these categories receive different treatment under airline regulations. Passengers flying internationally with psychiatric service dogs should confirm both airline and destination-country requirements before departure. A PSD letter may be part of a broader documentation package, but it does not replace proof of training, required airline forms, or import compliance documents.^source

Reviewing these rules in advance can help prevent delays at customs and prepare you for the differences between traveling with a standard pet, an emotional support animal, and a psychiatric service dog.

Aeromexico Emotional Support Animal Policy

An aeromexico emotional support animal does not receive the same legal recognition as a trained service dog under airline rules. Aeromexico treats emotional support animals as standard pets, meaning you must comply with all pet fees, carrier requirements, and in-cabin weight limits. This differs significantly from the accommodations available for a psychiatric service dog, which may qualify under disability travel protections when properly trained.^source

ESA vs Psychiatric Service Dog: What Is the Difference?

The primary distinction between an emotional support animal (ESA) and a psychiatric service dog (PSD) is task-based training. An ESA provides comfort through companionship, while a psychiatric service dog is individually trained to perform specific tasks related to a mental or psychiatric disability, such as interrupting panic episodes or providing grounding support.

This difference matters under the Aeromexico pet policy because emotional support animals follow regular pet rules, while a properly qualified psychiatric service dog may travel under service animal standards. Understanding this distinction is essential before relying on an ESA letter or a PSD letter for travel.^source

Support Animal Type	Legal Recognition for Flights	Documentation Commonly Used
Pet Dog	Standard pet fees	Health and vaccination records
Emotional Support Animal (ESA)	Treated as pet	ESA Letter
Psychiatric Service Dog (PSD)	May qualify as service dog	PSD Letter + DOT Forms

Does an ESA Letter Work for Aeromexico?

An ESA letter does not exempt your animal from Aeromexico’s pet travel requirements. Even if you have documentation from a licensed mental health professional, your emotional support animal must still travel under standard pet rules, including applicable fees and carrier restrictions.

Because airlines no longer recognize emotional support animals as service animals, many travelers confuse an ESA letter with documentation for a psychiatric service dog. These are not interchangeable for airline purposes.^source

When a PSD Letter May Matter for Travel

A PSD letter may support documentation for a passenger traveling with a psychiatric service dog, but a letter alone does not make a dog a service animal. The dog must be individually trained to perform disability-related tasks and may also require U.S. DOT forms or other airline documentation.^source

For travelers comparing ESA and PSD status, the key issue is not simply having a PSD letter, but whether the dog meets the functional standards required for service animal travel protections.

Aeromexico Service Dog Policy

An aeromexico service dog is defined as a dog individually trained to perform tasks for a person with a disability under the Air Carrier Access Act. This includes psychiatric service dogs that meet training requirements. Unlike emotional support animals, these dogs may travel in the cabin without following standard pet carrier rules.

The airline may require U.S. DOT forms attesting to the health, behavior, and training of your service dog. For psychiatric service dogs, passengers sometimes also carry supporting documentation such as an official PSD letter, though task training and regulatory compliance remain the determining factors.

You must submit all required forms according to airline deadlines to ensure your dog is approved for travel.

Your service dog must fit within your allotted foot space and remain under control throughout the flight. The dog cannot obstruct aisles or emergency exits. Small service dogs, including some psychiatric service dogs, may sometimes sit on a passenger’s lap when it can be done safely and within airline rules.^source

This comparison summarizes how the Aeromexico pet policy applies depending on how your animal travels. Standard pets must meet weight and carrier limits, while qualifying service dogs follow separate accommodation rules.

Travel Type	Weight Limit	Carrier Type
In Cabin	20 lbs	Soft-sided
Checked Pet	99 lbs	Hard-sided
Service Dog	No standard limit	No carrier

Frequently Asked Questions

Flying With Pets on Aeromexico

Flying under the Aeromexico pet policy can be straightforward when you prepare early and follow the airline’s requirements closely. Confirm your pet’s eligibility, verify carrier and weight limits, secure your reservation in advance, and review all health documentation before arriving at the airport. These steps reduce the risk of delays or denied boarding and help ensure a smoother trip for both you and your companion.

For international routes, preparation becomes even more important. Beyond Aeromexico’s own rules, you must comply with destination-country import requirements, including vaccination records, health certificates, and any applicable quarantine regulations. If traveling with a psychiatric service dog, you should also confirm whether additional documentation, including required airline forms, is needed before departure.

Overall, the Aeromexico pet policy can work well for passengers traveling with pets, emotional support animals following pet rules, or qualifying service dogs, provided all requirements are met in advance. Reviewing the rules early, organizing documentation, and understanding the differences between pet, ESA, and service dog travel will help you avoid problems and make your journey more predictable.
