Traveling with pets

Bringing your cat or dog with you on your trip is fun, but there are some rules you’ll have to follow. If you’re looking for information on traveling with service animals, we can also help with that.

Getting ready

We no longer let you check your pets through the PetSafe program. Pets can only fly in cargo when traveling with certain active-duty military or State Department employees. If you plan to fly with your pet, they must be a cat or dog and stay in the cabin with you (if there’s space available).

Some destinations don’t accept pets. Be sure to double-check before your flight.

On most flights, you can bring up to 2 pets per person. You must buy 2 seats if you’re bringing 2 pets. The second seat needs to be next to your assigned seat, so you can care for both pets.

Some of our planes have limited space under the middle seat. We only allow one pet per person on these aircraft:

  • A319
  • A320
  • A321neo
  • 737-800 and 737-8 (MAX 8)
  • 737-900 and 737-9 (MAX 9)

Make sure your pet fits

While there are no weight or breed limitations for pets, they must travel in either a hard-sided or soft-sided carrier. This carrier must fit under the seat in front of you or you cannot fly with your pet. The only animals allowed on planes without a pet carrier are service animals.

Hard-sided carrier

Hard-sided carriers. Maximum dimensions are 9 inches high, 17.5 inches long and 12 inches wide.

Gather paperwork

Some countries don’t allow pets to travel at all. Others have strict rules for rabies vaccines. Make sure you have all your paperwork and proof of vaccination in order before you leave.

All you have to do is select “Travel with a pet” as a traveler during booking on united.com. Or, you can go to My Trips to add a pet to an existing trip. You cannot add a pet to your trip on the United app.

We have a few recommendations to help you pack a pet-friendly travel kit:

  • Remember to bring all the essentials to care for your pet while you’re still at the airport, including a collapsible water bowl, leash, treats and plastic bags.
  • To keep them calm on the flight, it always helps to have a favorite toy, blanket or pillow that smells familiar.

At the airport

Here’s what you need to know once you get to the airport.

Checking in

Check in for your flight at the ticket counter. You’ll need both your own and your pet’s confirmation numbers, which you can find in your email or in My Trips. We’ll also give you a special bag tag for your pet’s carrier.

Pet relief areas

Many airports have places you can take your pet to use the bathroom while you’re there. Use the airport maps feature on the United app to see where they’re located.

Please note, therapy and emotional support cats and dogs must fly as pets, not service animals. They must follow all rules outlined in this policy both at the airport and on the plane.

On the plane

Once you’re on your flight, there’s only one rule you need to follow. Your pet must stay in their carrier with the door closed, and under your seat at all times.
