Yes—on United Airlines, your pet carrier counts toward your carry-on allowance. United treats an in-cabin pet carrier as your personal item because it must fit fully under the seat in front of you. In most cases, that means you can bring the pet carrier plus one additional item only if your fare permits it. For standard fares, that additional item is typically a full-size carry-on for the overhead bin. For Basic Economy (on most routes), you won’t be allowed an extra full-size carry-on, so your pet carrier would be the one item you bring onboard.
United requires your pet to remain in the closed carrier under the seat for the entire flight. Expect an in-cabin pet fee each way, and make sure to reserve early—United accepts a limited number of pets per flight. Always check United’s latest pet policy before you book, as rules and fees can change.
