Cabin limit and hold/cargo weight limits vary by route; verify dog + carrier or crate weight with the airline
Airline dog policy
Aeromexico
Aeromexico is Mexico's flag carrier and appears frequently in DogAbroad route data, including France to Mexico and many routes within North America and Latin America. Its current pet guidance offers small dogs and cats in the cabin as PETC and larger dogs as checked pets in the baggage hold, subject to aircraft quota, destination rules, breed handling, documentation and advance confirmation.
Book early and confirm aircraft acceptance.
Under-seat dimensions can vary by aircraft.
Fees can change by region and currency.
Booking tip
Reserve the pet service before travel and ask Aeromexico to confirm space on the exact flight and aircraft. For cabin travel, weigh dog plus carrier against the 9 kg limit and measure the carrier against the 40 x 30 x 20 cm published size. For checked pet travel, confirm the crate, total weight, check-in timing, seasonal fee and Mexico or destination authority paperwork before paying.
Why it can work
Aeromexico can be a practical first check for Mexico routes because it operates direct services into Mexico City, Cancun, Guadalajara and other Mexican airports and publishes both cabin and checked-pet pathways. For a France to Mexico search, its appearance as a direct operator is useful route evidence, but the booking still needs airline approval and destination document checks.
Restrictions
Cabin PETC is for dogs and cats only, with the 9 kg combined weight limit and one approved carrier. Checked pet service is limited to dogs, cats and cocks, with a published 45 kg combined pet-and-crate limit; heavier animals must use Aeromexico Cargo. Pets must be at least 8 weeks old. Acceptance conditions and documentation vary by origin and destination, and London routes require cargo handling.
Dog-owner notes
Aeromexico says pet services are quota-limited by aircraft and must be confirmed with the airline. Its business guidance lists PETC cabin carrier requirements and AVIH checked-pet rules, while the public Spanish pet page also highlights cabin, hold, service-animal and emotional-support categories. Prices are estimates and can vary without notice, so verify the live fee and route acceptance directly.
Final check before paying
Confirm the exact aircraft, route, dog breed, carrier size, temperature rules and destination import law directly with the airline. A country can allow dogs while a specific airline or aircraft refuses them.
