Flying United with a dog? Good news first: cabin travel is on the table, so your dog can ride under the seat beside you rather than down in the hold. The science here is simpler than it sounds, and this guide breaks United's rules into quick checks. Pixel, my Cavalier, has done enough boarding gates to know the drill cold. Let's get your paperwork airtight.
United Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.
How United Airlines handles your pet
UNITED: cabin only — PetSafe cargo program discontinued (cargo only available for active-duty military / State Dept employees). Cabin: cats and dogs in soft-sided (max 18x11x11 in / 45x27x27 cm) or hard-sided (max 17.5x12x9 in / 44x30x22 cm) carrier under the seat. Boeing 737 MAX limits carrier height to 10 in / 25 cm. NO weight or breed limitations on pets in cabin (per United policy). $150 each way. Plane-by-plane caps: 2 pets premium, up to 6 in economy on widebodies. Banned destinations include Australia, UK, Hawaii, Hong Kong, Ireland, Japan (UAE-Dubai), New Zealand, South Africa, etc. — full list per source. International rabies cert required, vaccinated ≥28 days before travel.

Other rules
Minimum age8 weeksverified 2026-07-20
United sets a hard floor on age: dogs in the cabin must be at least 8 weeks old. On domestic flights, puppies under 2 months are turned away at check-in. Confirm the puppy's date of birth before booking. Carry documentation showing the dog has passed 8 weeks. Book travel for a date after that threshold, not before it.
United applies no breed limitations to cabin dogs, so snub-nosed breeds are not banned from the cabin. Do not assume a brachycephalic breed disqualifies the booking. Book the cabin slot regardless of breed. Verify the carrier fits under the seat, since size and fit rules still apply even where breed restrictions do not.
Frequently asked
How many pets can I bring on United Airlines?
United Airlines allows 2 in the cabin, per passenger. Each pet needs its own carrier.
Can snub-nosed (brachycephalic) breeds fly United Airlines?
Snub-nosed breeds such as bulldogs, pugs and Persian cats are allowed in the cabin.
How much does it cost to fly a pet on United Airlines?
On flights within Metropolitan France, United Airlines charges from 150 in the cabin, one way per pet. Longer routes cost more — price your exact itinerary.
What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
United charges a cabin pet fee of 150 USD each way. A round trip means paying 150 USD outbound and 150 USD on the return. Budget 300 USD total for both legs. Pay the fee at check-in or during booking. Add this cost to the fare when comparing the true price of flying the dog.
United says yes to cabin dogs, keeps snub-nosed breeds welcome, and asks for a microchip plus that 8-week minimum age. Sort those before you book and the gate becomes easy, the way Pixel makes friends with every customs officer. Ready for your exact route and dates?
