The Best Pet Carriers For United Airlines


If you're planning to fly with your furry companion on United Airlines, there are some guidelines to follow. First off, pets can only be brought on board if there's space available. United doesn't have any weight or breed restrictions, but pets must be in a small carrier that fits under the seat in front of you. You're also limited to one pet per carrier, and that pet must be able to stand up and turn around comfortably.

If you're unsure which carrier to bring, United recommends a hard-sided carrier that's 17.5 inches long, 12 inches wide, and 7.5 inches high, or a soft-sided carrier that's 18 inches long, 11 inches wide, and 11 inches high. To make things easier, I've compiled a list of the best soft-sided pet carriers that meet United Airlines' size recommendation of 18” x 11” x 11” inches. With these options, you can rest assured that your pet will be comfortable and safe during your flight.

United Airlines has strict age requirements for pets traveling in their planes. For domestic flights, puppies and kittens must be at least 2 months old to be allowed onboard. This is to ensure that the young animals are strong and healthy enough to handle the stress of travel. However, for international flights, the age requirement is raised to 4 months old to comply with vaccination regulations. This policy prioritizes the safety and well-being of the pets, as well as the other passengers on the flight. United Airlines is committed to providing a comfortable and secure travel experience for all its passengers, including the furry ones.
