Traveling with a pet brings excitement, planning, and a fair share of questions. Airlines don’t all play by the same rules, and knowing the details before booking can save time, money, and stress. The American Airlines Pet Policy is designed to help small pets travel safely and comfortably, while also keeping flights organized for all passengers.

This guide breaks down everything travelers need to know, from in-cabin pet rules and fees to carrier size limits, health documentation, and restrictions. Whether the trip is a short domestic hop or a longer journey, understanding these guidelines helps avoid surprises at the airport.

Overview of the American Airlines Pet Policy

American Airlines allows certain pets to travel in the cabin on select flights. The policy focuses primarily on small cats and dogs that can remain comfortably inside an approved carrier throughout the journey. Unlike some airlines, American Airlines no longer accepts pets as checked baggage, and cargo options are limited to specific circumstances.

The goal of the American Airlines Pet Policy is safety. Cabin travel is considered the most secure option for small animals, as it keeps pets close and avoids temperature or handling concerns associated with cargo holds.

Types of Pets Allowed on American Airlines

Under the American Airlines Pet Policy, only specific animals are accepted for in-cabin travel.

Pets Allowed in the Cabin

• Domestic cats

• Domestic dogs

Other animals, including birds, reptiles, rodents, and exotic pets, are not permitted on American Airlines flights.

Each passenger may travel with one pet carrier, and the pet must remain inside the carrier at all times while onboard.

In-Cabin Pet Travel Rules

In-cabin pet travel is the most common and preferred option under the American Airlines Pet Policy. However, it comes with firm guidelines.

Basic In-Cabin Requirements

• The pet must fit comfortably in a soft-sided or hard-sided carrier

• The carrier must fit completely under the seat in front

• The pet must stay inside the carrier for the entire flight

• Pets are not allowed to sit on laps or move around the cabin

Only a limited number of pets are allowed per flight, so reservations fill up quickly. Early booking is strongly recommended.

American Airlines Pet Fees

Traveling with a pet involves an additional fee, separate from standard baggage charges.

Current Pet Travel Fee

• $125 per carrier, per one-way trip

For trips that include a voluntary layover longer than four hours, an additional fee may apply. Fees are typically paid at the airport check-in counter on the day of travel.

Pet fees are non-refundable and apply regardless of seat type or ticket class.

Pet Carrier Requirements

Carrier rules are one of the most important parts of the American Airlines Pet Policy. A carrier that does not meet size or design standards can result in denied boarding.

Approved Carrier Types

• Soft-sided carriers are recommended due to flexibility

• Hard-sided carriers are allowed if they fit under the seat

Maximum Carrier Size (In-Cabin)

Carrier dimensions must fit under the seat, which varies by aircraft. A commonly accepted maximum size is approximately:

• 18 x 11 x 11 inches (length x width x height)

Carrier Design Rules

• Leak-proof bottom

• Proper ventilation on at least two sides

• Secure zippers or fasteners

• Clean and odor-free condition

The carrier counts as one carry-on item, meaning additional personal items must comply with carry-on limits.

Seating Restrictions for Pet Travel

Not all seats are eligible for in-cabin pet travel.

Seats Where Pets Are Not Allowed

• Exit rows

• Bulkhead seats

• First Class lie-flat seats on select aircraft

Window or middle seats typically work best, as they allow carriers to fit more easily under the seat.

Health and Documentation Requirements

American Airlines does not require health certificates for most domestic flights, but pets must be healthy and fit to travel.

Health Guidelines

• Pets should be at least 8 weeks old

• Pets must be clean, calm, and free of strong odors

• Aggressive behavior or excessive noise may result in removal from the flight

For international travel, destination countries may require:

• Health certificates

• Vaccination records

• Microchips

• Import permits

These requirements are set by government authorities, not the airline, and must be researched well in advance.

Breed Restrictions and Considerations

The American Airlines Pet Policy does not publish a strict breed ban for in-cabin pets. However, snub-nosed (brachycephalic) breeds may face extra scrutiny due to breathing risks.

Examples of Snub-Nosed Breeds

• Bulldogs

• Pugs

• Persian cats

• Shih Tzus

While these breeds are not outright banned from cabin travel, owners are encouraged to consult a veterinarian before flying, especially on longer routes.

Age and Size Limits for Pets

Pets must be small enough to stand, turn around, and lie down naturally inside the carrier.

Key Rules

• Minimum age: 8 weeks

• No maximum age, but health must be stable

• Overly large pets that cannot fit comfortably are not allowed

If a pet appears cramped or distressed, airline staff may deny boarding for safety reasons.

Booking a Flight With a Pet on American Airlines

Adding a pet is not something that can always be done online.

How to Add a Pet Reservation

• Contact American Airlines reservations by phone

• Confirm space availability for in-cabin pets

• Pay the pet fee at the airport

Since pet spots are limited, booking early increases the chance of approval.

Airport Check-In Process With a Pet

Online check-in is usually not available for passengers traveling with pets.

What to Expect at the Airport

• Arrive early to allow extra time

• Check in at the ticket counter

• Airline staff may inspect the carrier

• Pet must remain inside the carrier during inspection

Security screening requires removing the pet from the carrier briefly while the carrier goes through the X-ray machine. Pets are carried through the metal detector by hand.

Layovers and Connecting Flights

Connecting flights are allowed under the American Airlines Pet Policy, but long layovers can add complexity.

Important Layover Rules

• Layovers over four hours may incur extra fees

• Pet relief areas vary by airport

• Pets must remain in the carrier inside terminals

Shorter connections are generally easier for pets and owners alike.

International Travel With Pets

International pet travel is more complex and requires careful planning.

Key International Considerations

• Some countries prohibit in-cabin pets

• Quarantine rules may apply

• Documentation requirements vary widely

American Airlines may restrict pet travel to certain international destinations based on local regulations.

Emotional Support Animals and Service Animals

Policies for animals assisting passengers have changed in recent years.

Service Animals

• Trained service dogs are accepted free of charge

• Required documentation must be submitted in advance

• Dogs must remain under control at all times

Emotional Support Animals

• Emotional support animals are treated as pets

• Standard pet fees and carrier rules apply

This update aligns with U.S. Department of Transportation regulations.

Seasonal and Weather Restrictions

Extreme temperatures can affect pet travel, even for in-cabin pets.

Weather-Related Considerations

• High heat or cold may limit acceptance

• Summer and winter travel requires extra care

• Early morning or evening flights are often safer

While in-cabin pets are less affected than cargo animals, safety checks still apply.

Tips for a Smooth Pet Travel Experience

Flying with a pet can be smooth with proper preparation.

Helpful Travel Tips

• Introduce the pet to the carrier weeks before travel

• Avoid feeding right before the flight

• Attach ID tags to the carrier

• Bring absorbent pads and wipes

• Choose direct flights when possible

Calm preparation makes the journey easier for both pets and fellow passengers.

Common Reasons Pets Are Denied Boarding

Understanding common mistakes helps prevent issues at the airport.

Common Issues

• Carrier too large or damaged

• Pet appears sick or aggressive

• Required documentation missing

• Flight pet limit already reached

Double-checking details before departure reduces the risk of disruption.

Advantages of Flying With Pets on American Airlines

The American Airlines Pet Policy offers several benefits for pet owners.

Key Advantages

• Pets travel in the cabin, close to owners

• Clear carrier and fee guidelines

• Extensive domestic route network

• Dedicated service animal accommodations

For small pet owners, these features make American Airlines a practical choice.

Final Thoughts on the American Airlines Pet Policy

The American Airlines Pet Policy is straightforward but firm. It prioritizes safety, comfort, and consistency across flights. Small cats and dogs can travel in the cabin when rules are followed closely, fees are paid, and reservations are secured early.

From carrier dimensions and pet fees to health checks and airport procedures, preparation is the key to a smooth journey. Understanding these guidelines ahead of time helps avoid stress and ensures pets arrive calm, safe, and ready for the next adventure.
