United Pet Carrier Size
Under United Airlines pet policy, United Airlines has certain pet carrier sizes in the cabin, but on 737 MAX planes the space under the seat is shorter, so your carrier must be lower in height than usual.
Standard limits:
- Hard-sided carriers: up to 17.5 inches long x 12 inches wide x 7.5 inches high (44 cm x 30 cm x 19 cm).
- Soft-sided carriers: up to 18″ L × 11″ W × 11″ H.
- 737 MAX specific: Under-seat height is 10; your carrier must fit at 10 inches high on these aircraft. Check your aircraft type in your reservation.
The carrier should have air holes on at least two sides so that your pet can breathe easily and a leak-proof bottom to stop any mess from spilling out. This helps to keep your pet comfortable and the area clean.
Ensuring a Comfortable Fit For Your Pet
Meeting airline size rules is important, but your pet’s comfort matters too. Your pet should be able to stand up and turn easily inside the carrier without hitting their head or feeling tight.
A quick way to check is to measure your pet’s height (floor to the top of their shoulders) and their length (nose to the base of their tail). The carrier should be just a bit bigger than those measurements.
Where You Can (and Can’t) Sit
According to United Airlines pet policy, the carrier should fit under the seat in front of you for the entire flight, but some seats are not allowed. You cannot sit in such as:
- Exit rows seats
- Bulkhead seats (the ones with a wall in front)
- United Polaris, United First, or United Business on certain premium aircraft, as there is not enough space under the seat.
Always double-check your seat assignment while booking your ticket. Understanding pet-friendly seating right from the start will make your travel journey smoother.

Note: Remember, your reservation is not complete until you have received confirmation from the airline.
