Who can fly

The only service animals permitted on United and United Express flights are dogs over 4 months old who are trained to perform tasks for someone with a disability.

Types of animals

We only allow service dogs flying with their owners, or service dogs in training who are flying with their trainers, on our flights for free. All other cats and dogs fly as pets. Any other type of animal needs to stay at home.

What you need to fly

If you’re traveling with a service animal, we require you complete a couple of Department of Transportation (DOT) forms. These forms will ask for your service animal’s weight, breed, vaccination information and vet information.

When you fill out these forms you guarantee that your dog will not relieve themselves at the gate or on the plane. You also promise they are well trained and in your control at all times. If your dog does need to relieve themselves while at the airport, use the United app to find a designated animal relief area.

For domestic flights, you can complete these forms electronically and save them to your trip in My Trips. Or you can download and print them. You must print and keep these forms with you while at the airport and on the plane.

For international flights, as well as flights to Hawaii and Guam, the forms can’t be completed electronically. You’ll need to print and carry them with you during your trip.

How to fly

There are two parts to flying with a service animal: booking your trip and choosing the right seat on the plane.

Book your trip

The first thing you’ll need to do is let us know you’re bringing a service dog. How you do this depends on where you’re going.

For domestic flights

You have two options:

1. When booking your ticket check the service animal option when entering your traveler information.

2. When viewing your trip after booking your ticket, select the option to add a service animal.

For international flights

This includes flights to Hawaii and Guam.

Because there might be destination-specific rules for traveling with a service dog, you’ll need to call our accessibility desk at 1-800-228-2744 to add one to your trip.

Choose your seat

  • Your dog should sit in the floor space in front of your seat. They can’t be in the aisle or the floor space of the travelers next to you.
  • You can’t sit in an exit row with a service animal.
