United Airlines Pet Policy + 1-877-419-4448

United Airlines Pet Policy provides clear rules for passengers traveling with pets, whether in the cabin or via cargo. Small cats and dogs are welcome in-cabin on most domestic and international flights, as long as they remain in an approved carrier that fits under the seat. Larger animals must be shipped through the airline’s Pet Safe program, which prioritizes animal welfare and safety. This pet policy reflects United’s commitment to responsible travel, ensuring both pets and passengers have a stress-free journey. Always review the latest updates, as policies may change based on seasonal, safety, or government regulations.

2. In-Cabin Pet Travel with United Airlines
The United Airlines Pet Policy allows small pets to travel in the cabin under specific conditions. Only dogs and cats are allowed, and they must remain in a soft- or hard-sided carrier that fits beneath the seat in front of you. The total in-cabin pet fee is $125 per segment. Reservations should be made early since only a limited number of pets are accepted on each flight. The pet must remain in the carrier throughout the journey and be at least 2 months old for domestic flights.

3. United Airlines Pet Safe Program for Larger Animals
For pets that cannot travel in-cabin due to size or breed, United Airlines Pet Policy offers the Pet Safe program. This cargo service provides a climate-controlled, pressurized, and secure environment for pets traveling separately from their owners. Pet Safe is overseen by trained professionals and is designed to keep pets safe from extreme temperatures and stress. Health certifications and approved travel crates are mandatory. Pet Safe is not available during peak heat seasons or for certain snub-nosed breeds due to health risks.

4. Required Documents for Pet Travel
Traveling under the United Airlines Pet Policy requires preparation. For all pets, up-to-date vaccination records are essential. If you're flying internationally or using the Pet Safe cargo service, a health certificate signed by a licensed veterinarian is required within 10 days of departure. Some destinations may also request proof of microchipping or rabies titer test results. Pet owners should also verify entry regulations at their destination, as some countries may enforce quarantine or ban certain breeds altogether.

5. Carrier Guidelines and Pet Size Restrictions
A vital part of the United Airlines Pet Policy is the carrier requirement. In-cabin pets must be housed in a leak-proof, well-ventilated carrier. Soft-sided carriers must not exceed 18” x 11” x 11”. Your pet should be able to stand, turn around, and lie down comfortably inside. Only one pet is allowed per carrier and per passenger. If your pet doesn’t meet these requirements, they’ll need to be booked using the cargo program instead.

6. Restrictions by Breed and Animal Type
According to United Airlines Pet Policy, not all animals are eligible for air travel. Snub-nosed breeds such as Pugs, Bulldogs, and Persian cats are restricted due to their respiratory vulnerabilities, especially in cargo travel. Additionally, United does not allow non-household animals such as rodents, reptiles, or birds in the cabin or cargo. Breed restrictions help prevent in-flight health issues and ensure compliance with international laws. Service animals are the only exception, though documentation is still required.

7. United Airlines Pet Policy on Service Animals
United Airlines follows the DOT guidelines for service animals. As part of its Pet Policy, only properly trained service dogs are permitted in the cabin free of charge. Emotional support animals no longer qualify under this category. Passengers must submit a U.S. DOT Service Animal Air Transportation Form and a Behavior Attestation Form prior to flying. These dogs must stay harnessed and remain at the handler’s feet without occupying a seat.

8. Check-In and Airport Procedures
Passengers flying with pets under the United Airlines Pet Policy must check in at a full-service counter. Online and kiosk check-in are not permitted for pet travelers. Airport staff will verify the pet reservation, inspect the carrier, and attach the pet ID tag. At TSA, pets must be taken out of their carriers and held or leashed while the carrier is scanned. Pets must return to the carrier immediately after security screening.

9. Traveling Internationally with Pets
United Airlines Pet Policy for international travel includes extra layers of documentation. Pets must be at least 4 months old and may require special vaccinations, microchipping, and health certificates tailored to the destination country. Some countries may not accept pet imports at all, while others enforce strict quarantine laws. Pet owners should consult both the USDA and the destination country’s embassy before booking. United recommends planning international pet travel at least 30 days in advance.

10. Managing Layovers and Connecting Flights
According to United Airlines Pet Policy, pets cannot be booked on flights with layovers exceeding 4 hours domestically or 24 hours internationally unless special approval is granted. Connecting pets traveling via Pet Safe are held in climate-controlled environments between flights. United discourages tight layovers when traveling with pets to minimize stress and confusion. It’s important to plan for hydration, potty breaks, and quiet spaces when flying with your pet on connecting routes.

 Final Conclusion 
The United Airlines Pet Policy is one of the most detailed and passenger-friendly among major U.S. carriers. Whether you’re flying domestically with a small dog or internationally with a larger breed, United offers structured solutions to keep your pet safe and your experience stress-free. From in-cabin travel options for small pets to the specialized Pet Safe cargo program, every aspect of the policy is designed with safety, comfort, and compliance in mind.
