Planning to travel with your dog or cat? Knowing the American Airlines pet policy before you book saves money and a lot of last-minute panic.

Can my pet fly in the cabin on American Airlines?
On most airlines, small dogs and cats can travel in the cabin as long as they fit comfortably in an airline-approved carrier that slides under the seat in front of you. Your pet generally must stay in the carrier the whole flight, and a one-way pet fee usually applies. Space per flight is limited, so booking your pet's spot early is essential.
- Size: the pet must stand, turn around and lie down in the carrier.
- Carrier: soft-sided, leak-proof and ventilated; it often counts as your carry-on or personal item.
- Fee: a pet-in-cabin fee typically applies each way — amounts vary, so call to confirm.
- Limits: a capped number of pets per cabin means first-come, first-served.
In-cabin vs cargo vs service animals
It helps to know which lane your animal falls into, because the rules and costs are very different.
| Travel option | Who it's for | Key conditions (vary — call to confirm) |
|---|---|---|
| In-cabin pet | Small dogs & cats | Must fit in an approved carrier under the seat; a fee usually applies each way |
| Checked / cargo | Larger pets (where allowed) | Not offered by every airline; weather and breed restrictions apply |
| Service animal | Trained service dogs | Travels free with required DOT forms — different rules than pets |
| Emotional support animal | — | Most U.S. airlines no longer treat ESAs as service animals; they fly as pets |
Some larger pets may travel as checked baggage or cargo on American Airlines depending on aircraft, route and weather, but availability is limited and seasonal heat or cold embargoes can apply.
What you'll need before you fly
- An approved carrier sized to your pet and the under-seat space.
- Health documentation — many routes and destinations require a recent vet health certificate.
- A confirmed pet reservation — don't assume space; book it.
- Extra airport time, since pets usually can't be added at a kiosk.
Choosing the right pet carrier
The carrier is where most in-cabin pet plans succeed or fail. It has to fit under the seat in front of you and give your pet enough room to stand, turn around and lie down — a balance that rules out both oversized hard cases and cramped bags. Soft-sided carriers usually work best because they flex into the under-seat space, and a leak-proof, well-ventilated design keeps your pet (and your neighbours) comfortable on a long flight.
- Measure the under-seat space for your specific aircraft and cabin where possible.
- Soft-sided beats hard-sided for in-cabin flexibility.
- Add an absorbent pad and a familiar item to keep your pet calm.
- Label the carrier with your name and contact details.
Tips for a calm flight with your pet
A little preparation goes a long way toward a smooth trip. Exercise your pet beforehand so they're more relaxed, and avoid a heavy meal right before departure to reduce the chance of an upset stomach. Get them comfortable in the carrier days ahead rather than springing it on them at the airport, and check whether your vet recommends anything for travel anxiety. Book direct flights where you can — fewer connections mean less stress for everyone — and build in extra time so you're never rushing a nervous animal through a busy terminal.
Service animals are not pets
Trained service dogs travel under different rules than pets — typically free of charge, but with required U.S. Department of Transportation forms submitted in advance. Most U.S. airlines no longer recognise emotional-support animals as service animals; they now travel as regular pets under the standard American Airlines pet policy. Rules here change frequently, so confirm before you book.
Fees, restrictions and the fine print
- Breed restrictions — some snub-nosed (brachycephalic) breeds face limits, especially in cargo.
- Weather embargoes — extreme heat or cold can pause cargo pet travel.
- International rules — destination countries set their own import and quarantine requirements.
- Fees vary — we won't quote exact dollar amounts here because they change; call to confirm.
