Service Dogs on United Airlines: 2026 Policy Guide

United Airlines Service Dog Policy

United Airlines accommodates trained service dogs on all flights in compliance with the DOT's Air Carrier Access Act (ACAA). United's policy focuses on ensuring the safety and comfort of all passengers while respecting the rights of service dog handlers.

Before Your Flight

United requires the DOT Service Animal Air Transportation Form submitted at least 48 hours before departure. Submit through United's website, mobile app, or by calling the Accessibility Desk at 1-800-228-2744. When booking your ticket, add the service dog notation to your reservation. Request a bulkhead or window seat for maximum floor space. For large dogs, consider Economy Plus or a premium cabin.

At the Airport

Check in at a staffed counter to verify your service dog documentation. Service dogs are welcome in all United Club lounges. The TSA process is the same regardless of airline. Walk through the checkpoint with your dog on leash. The dog does not go through X-ray equipment.

United's major hubs have pet relief areas: EWR (Newark) in Terminals B and C post-security, IAH (Houston) in Terminals A, B, C, and E, ORD (Chicago O'Hare) in multiple terminals, DEN (Denver) throughout the airport both pre and post-security, SFO (San Francisco) in all terminals, and LAX (Los Angeles) outside each terminal.

In Flight

Your service dog must remain on the floor at your feet throughout the flight, be on a leash or harness at all times, not block the aisle or emergency exits, behave calmly without barking or growling, and be housebroken. Service dogs are permitted in all cabin classes. Economy Plus offers extra legroom with more floor space for medium to large dogs. United Polaris on international routes offers lie-flat seats with substantial floor space for large service dogs on long flights.

Long-Haul Flights

For flights over 8 hours, exercise your dog thoroughly before the flight. Limit food intake 4 to 6 hours before departure to reduce relief needs. Bring absorbent pads as backup for very long flights. Carry a collapsible water bowl and bring a familiar blanket or mat for your dog's comfort on the cabin floor.

International Flights

United flies to over 100 international destinations. Service dog requirements vary significantly by country. Common requirements include an ISO-compliant microchip, rabies vaccination with some countries requiring a titer test, health certificate issued within 10 days of travel, import permit from the destination country, and possible quarantine. For complete details, see our international service dog travel guide.

If Problems Arise

United is required to have a Complaint Resolution Official (CRO) available at every airport. Request to speak with the CRO immediately if you encounter an access issue. The CRO has authority to resolve disability-related complaints on the spot. If unsatisfied, file a written complaint with United and the DOT. For complete guidance, see our step-by-step response guide.
