United allows domesticated cats, dogs, rabbits and birds to travel accompanied in the aircraft cabin on most flights within the U.S. An in-cabin pet may be carried in addition to a carry-on bag and is subject to a $125 service charge each way. There is an additional $125 service charge for each stopover of more than four hours within the U.S. or more than 24 hours outside of the U.S.
In-cabin pet kennels
A pet traveling in cabin must be carried in an approved hard-sided or soft-sided kennel. The kennel must fit completely under the seat in front of the customer and remain there at all times. The maximum dimensions for hard-sided kennels are 17.5 inches long x 12 inches wide x 7.5 inches high (44 cm x 30 cm x 19 cm). The recommended maximum dimensions for soft-sided kennels are 18 inches long x 11 inches wide x 11 inches high (46 cm x 28 cm x 28 cm). Soft-sided pet carriers may exceed these dimensions slightly, as they are collapsible and able to conform to under-seat space without blocking the aisle. With the exception of birds, there may only be one pet per kennel, and the animal must be able to stand up and turn around comfortably. Two birds may travel in the same kennel.
Trained service animals are allowed in-cabin to accompany qualified customers with disabilities. Service animal procedures differ from standard in-cabin pet procedures. Visit the Service Animals
section for more information.
