Hey, My brother 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. https://rightcheckin.com/airlines/united-airlines-san-antonio-office-in-united-states/
