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.
If you have a MileagePlus® account, you can sign in and complete these forms online and save them to your trip. If you don’t have an account, you can complete the accessible PDF versions linked below. Whether you fill out the forms online or as PDFs, you must print and keep them 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.
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.
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 put your service dog in a pet-carrier if you choose, as long as it meets size requirements.
You can’t sit in an exit row with a service animal.
