Hey, My cousin recently visited the United Airlines San Antonio Office » to inquire about their pet policy and had a positive experience. The staff was courteous and provided clear information on traveling with pets. They explained that United Airlines allows only cats and dogs to travel in the cabin, provided they fit comfortably in an airline-approved carrier under the seat in front of you. The fee for in-cabin pet travel is typically $125 each way, and it's important to reserve space for your pet in advance, as availability is limited per flight. He appreciated the staff's professionalism and the comprehensive guidance they provided, which made him feel confident about traveling with his pet.
