Aeroméxico pet policy — what it publishes, and what it does not

Aeroméxico accepts pets in the cabin but does not publish a maximum carrier size, so we will not compute a fit rather than guess one. Aeroméxico does not publish a cabin-pet fee on its own policy page. Confirm the under-seat allowance with Aeroméxico before you book.

Aeroméxico publishes no maximum carrier size

Aeroméxico does not publish a maximum carrier height, so there is nothing to compare against the other airlines we track. Confirm the under-seat allowance directly with Aeroméxico.

Carriers that fit Aeroméxico

Aeroméxico publishes no under-seat size limit, so nothing below is matched against one. See the full Aeroméxico carrier shortlist →

This table ranks by Aeroméxico’s size limit — not by your pet. The weight under each carrier is what that size is rated to hold. A bag can clear the airline and still be the wrong size for the animal, which is the most common reason one goes back — measure your pet first →

How to confirm your actual under-seat space

Aeroméxico's number is its published maximum, not a guarantee for your exact seat. Before you buy or fly:

1. Check which aircraft operates your flight (in your booking or on a seat-map site).
2. Avoid bulkhead and exit rows — bulkheads have no under-seat storage and most airlines ban pets there — and check this airline's seat rules above.
3. Call Aeroméxico to confirm under-seat dimensions for that aircraft, or
4. Choose a collapsible / flexible-height carrier that adapts to a tighter space.
