How American Airlines pet travel generally works
General guidance. Policies vary widely by route, aircraft and animal — always confirm before you book.
Small pets may travel in-cabin in an approved carrier on many routes; larger animals may need cargo or aren't accepted on some routes.
Each flight allows only a few pets in-cabin — they fill up, so book early.
Trained service animals follow separate rules and documentation requirements from pets.
Carriers must meet size rules and fit under the seat; some destinations require health paperwork.
Certain breeds, routes, temperatures and international destinations have added rules or embargoes.
Pet policies are among the most route- and aircraft-specific rules an airline has. We don't quote fees — an agent confirms exactly what's possible for your flight before anything is charged.
In-cabin vs. cargo — the basics
Policies vary widely by route, aircraft and animal. Always confirm before you book.
In-cabin
Small pets
- Small dogs/cats in an approved carrier that fits under the seat
- Only a few spots per flight — they fill early
- Not offered on every route or aircraft
- Carrier counts toward your carry-on allowance
Cargo / checked
Larger animals
- For animals too large for the cabin, where accepted
- Temperature and seasonal embargoes can apply
- Not available on all routes or aircraft
- Health documentation is often required
Pet travel checklist
Sort these before you fly — spots and rules are strict.
- Book early — in-cabin pet spots are capped per flight
- Right-sized carrier that fits under the seat and meets airline rules
- Health paperwork if your route or destination requires it
- Check breed & route rules — some are restricted or embargoed
- Service animals follow separate rules and documentation from pets
Because spots are limited and rules are strict, a phone call is the safest way to book pet travel. We'll confirm exactly what's allowed on your route and reserve the space.
