The United Airlines Pet Policy provides structured guidance for pet owners planning air travel. Passengers may bring small dogs and cats in the cabin with an approved carrier. Larger animals must travel via United’s PetSafe® program, which focuses on safety and comfort. Advance booking, health certificates, and vaccination records are required. Breed and weather restrictions may affect eligibility. Emotional support animals are not recognized as service animals under current DOT regulations. Travelers are encouraged to review all pet travel guidelines well in advance. United Airlines ensures pets are cared for from departure to arrival through responsible, pet-friendly procedures.
