American Airlines Pet Policy: The 2026 Complete Travel Guide

Planning a trip with your animal companion requires careful preparation. As a pet-friendly carrier, American Airlines provides multiple options for pet travel. Understanding the specific regulations for the American Airlines pet policy is crucial for a smooth and safe journey.

What are the rules for in-cabin pet travel on American Airlines?

American Airlines allows small dogs and cats to fly in the passenger cabin. The pet and their carrier must not exceed 20 pounds combined, and the soft-sided carrier must not exceed 18″ L x 11″ W x 11″ H. The in-cabin pet fee is $150 per carrier, each way.

For in-cabin travel, pets must remain inside their closed carrier under the seat in front of you for the entire flight. American Airlines restricts in-cabin travel on flights longer than 12 hours.

In-Cabin Eligibility and Rules:

• Age requirements: Pets must be at least 8 weeks old for domestic flights (or 16 weeks for some international routes).
• Species: Only small dogs and cats are permitted in the cabin.
• Locations: Allowed on flights within the U.S., Canada, Mexico, Central America, and select Caribbean destinations. Transatlantic, transpacific, and flights to Hawaii or South America have strict restrictions.

How do I add a pet to an American Airlines flight?

You can add a pet to an American Airlines flight during the online booking process or through the mobile app. Navigate to the “Special Services” or “Additional Services” tab and select “Add carry-on pets”. Alternatively, you can call customer service to attach the pet reservation to your ticket.

Space for pets in the cabin is strictly limited (typically up to seven pets on mainline flights and five on American Eagle). You must book early to secure a spot. If your plans change or you encounter issues online, call the airline directly to confirm your American Airlines pet travel reservation.

Can a 30 pound dog fit under an airplane seat?

No, a 30-pound dog cannot comfortably or legally fit under an airplane seat on American Airlines. The airline enforces a strict maximum combined weight limit of 20 pounds for the pet and the carrier together. A 30-pound dog must travel via American Airlines pet cargo.

Attempting to bring a dog that exceeds the weight limit or carrier dimensions into the cabin will result in denied boarding. Your dog must be able to stand, turn around, and lie down comfortably inside a carrier that fits completely under the seat in front of you.

What are the American Airlines pet cargo rules for 2026?

American Airlines pet cargo (managed by PetEmbark) accommodates larger dogs, cats, and select other species. Pets fly in temperature-controlled compartments. Owners must supply an IATA-compliant hard-sided kennel. Cargo is restricted during extreme temperatures (above 85°F or below 45°F) and for snub-nosed breeds.

When pets outgrow the cabin limits, American Airlines pet cargo provides a safe alternative. Cargo travel requires advanced booking, strict health documentation (issued within 10 days of travel), and specialized crates.

Cargo Travel Guidelines:

• Eligible animals: Dogs, cats, birds, rabbits, guinea pigs, hamsters, and some reptiles.
• Temperature limits: Ground temperatures must be between 45°F and 85°F at all stops. A vet’s acclimation letter is required for temperatures between 20°F and 44°F.
• Breed restrictions: Brachycephalic (snub-nosed) breeds—like Pugs, Bulldogs, Boxers, and Persian cats are strictly prohibited in cargo due to respiratory risks.

Cargo Temperature and Breed Rules

How do I book AA pet cargo reservations?

You must book American Airlines pet cargo reservations through the PetEmbark service. Reservations can be requested up to 10 days before departure via the American Airlines Cargo website or by calling the American Airlines pet cargo phone number directly.

For American Airlines pet cargo international travel, you may be required to use an IATA-regulated professional pet shipper or freight forwarder. The airline mandates strict adherence to customs regulations, import permits, and international health certificates for destination countries.

How much does American Airlines pet cargo cost?

The American Airlines pet cargo cost varies significantly based on the pet’s size, crate dimensions, destination, and whether the flight is domestic or international. Shippers pay the freight charges plus a standard $150 handling fee per air waybill.

Active-duty U.S. Military personnel traveling on PCS or TDY orders receive a 50% discount on published cargo rates for cats and dogs. To secure an exact price for your specific route, you must use the rate calculator on the American Airlines Cargo website.

What are the rules for service dogs and ESAs on American Airlines?

American Airlines allows fully trained service dogs to fly in the cabin for free. Handlers must submit the DOT Service Animal Air Transportation Form 48 hours before the flight. Emotional Support Animals (ESAs) are no longer recognized as service animals and must fly as regular pets subject to standard fees.

Service dogs must be trained to perform tasks for a person with a disability. They must fit at the passenger’s feet or on their lap without blocking the aisle.

Can I buy my 50 lb dog a seat on a plane?

No, you cannot buy a seat for your 50-pound dog on American Airlines. Commercial airlines do not allow pets to occupy passenger seats. A 50-pound dog is too large for the cabin and must be transported via American Airlines pet cargo in an approved hard-sided kennel.

The only exception to size and carrier rules in the cabin is for trained service dogs. If a service dog is too large to fit in the foot space of a single seat, the handler may purchase an additional seat to secure extra floor space, but the dog still cannot sit on the actual seat.

What happens if my dog barks on the plane?

If your dog barks excessively, growls, or acts aggressively on the plane, flight attendants may classify the animal as disruptive. For standard pets, they must remain zipped in their carrier. For service animals, failure to maintain control can result in the dog being removed from the cabin.

American Airlines requires all animals to be well-behaved in public settings. Minor whining or a single bark might be overlooked, but persistent noise or aggressive behavior violates the American Airlines pet policy and DOT regulations.
