Flying With a Pet Inside the US
What to check before booking a flight with a dog or cat: cabin vs. cargo, carriers, airport security and paperwork.
Cabin, cargo or not at all
- Most US airlines allow small dogs and cats in the cabin in a carrier that fits under the seat in front of you. Larger pets may travel as cargo on some airlines, and some airlines do not carry pets in cargo at all.
- Cabin pet spots are limited per flight, so reserve your pet when you book your own ticket.
- Short-nosed (brachycephalic) breeds face higher breathing risks during air travel; many airlines restrict them. Talk to your veterinarian first.
Airport security
- At TSA screening, your pet is taken out of the carrier and carried or walked through the metal detector while the empty carrier goes through the X-ray. Keep your pet on a leash.
Paperwork
- Requirements differ by airline and destination state. Some airlines and states ask for a health certificate issued by a veterinarian within a set number of days before travel.
- Always read your airline's current pet policy and fee page before booking — these change often.
Service and emotional support animals
- Under the US Department of Transportation rules, airlines must accept trained service dogs but may treat emotional support animals as regular pets.
