United Airlines ESA and Service Dog Policy Guide

by | May 16, 2026 | Emotional Support Animal Letter | 0 comments

Many individuals now like travelling with their pets, most particularly dogs and cats. Some of the passengers wish to carry the animals in the aircraft, while others have trained dogs that help people with disabilities. In this blog, we will clearly explain united emotional support animal policy, pet travel rules, and service dog guidelines so you can easily understand which animals are allowed, what the requirements are, and how to follow the travel process.

United Airlines Pets Policy

The pet will have to travel in an approved carrier that fits under the seat of the airplane. United Airlines permits small dogs and cats and allows them to travel together with their owners. Though this service may not be allowed in some countries and on some planes. Therefore, it has to be checked during the time of booking. United Airlines usually charges around $150 each way for in-cabin pets, and you must book in advance.

United Emotional Support Animal Policy

United Airlines no longer allows Emotional Support Animals in a special category as it did before. Emotional support animals are now treated like pets and fall under the United travel pet policy. This means you will have to book the pet under the airline’s pet policy, use the approved pet carrier, and ensure the pet carrier is under the seat. Apart from this, there is also a pet fee for airline transport if traveling in the airline cabin. Overall, ESA travel on United no longer follows the rules for service dogs—ESAs must now follow the pet rules, and only trained service dogs receive special access.

Are service dogs allowed?

Yes, trained service dogs are permissible in United Airlines. A service dog is a well-trained dog that carries out special duties to help an individual with a disability. As an example, leading a person with vision impairment, sensing/warning of an attack, mobility assistance, or trained grounding duties during a panic attack. United Airlines generally allows trained service dogs that perform disability-related tasks.

Required Forms for Service Dogs on United Airlines

To fly with a service dog on United Airlines, you will mostly need DOT forms.

1. DOT Service Animal Air Transportation Form

On this form, you confirm that:

  • The dog is a trained service animal
  • The dog is healthy
  • The dog is safe for public behavior
  • The dog will remain under the handler’s control

2. DOT Service Animal Relief Attestation Form (for long flights)

If the flight is 8 hours or longer, the Relief Attestation Form is usually also required. On this form, you confirm that the dog.

  • can manage without relief for a long duration
  • Or that you have made proper arrangements

When to submit the forms?

Best Practice: Submit the forms/documents at least 48 hours before travel. For last-minute travel, verification may be done at the airport, but there is a higher risk of delays or issues.

What details need to be filled out?

When submitting the required DOT forms, you may need to provide:

  • Passenger/Handler details – name, contact information, and flight details
  • Service dog information – dog’s name and basic details
  • Training and behavior confirmation -that the dog is a trained service animal and is safe in public
  • Health declaration – that the dog is healthy and fit to travel
  • Relief plan for flights 8 hours or longer- how the dog will manage bathroom needs
  • Final handler confirmation/signature- to complete the form submission

United Airlines Rules for Flying with a Service Dog

Service dogs are allowed free of charge, but the rules are strict.

1. Dog behavior requirements

  • The dog must:
  • remain calm
  • not be aggressive
  • not bark or growl excessively
  • Do not disturb other passengers
  • remain “under control” at the airport and on the flight

If the dog exhibits disruptive behavior, the airline may:

  • issue a warning
  • refuse to allow the dog to fly

2. Leash/Harness rules

  • Service dogs must generally be:
  • on a leash, harness, or tether
  • The owner must maintain full control.

3. Seating rules

The service dog must:

  • fit in the passenger’s foot area
  • not block the aisle
  • There may be restrictions in emergency exit row areas
  • No blocking aisles or emergency exits

United Airlines Breed & Size Restrictions:

For service dogs, the focus is not on the breed, but rather on behavior, safety, and suitability for the passenger space. The dog must be able to travel safely in the aircraft without blocking space. Pet restrictions are different from service dog restrictions. Pets are required to be in a carrier. Service dogs are not (normally) required to be in a carrier. The size limit in the pet policy is much stricter.

What if the service dog is too large?

The airline may request that you buy an additional seat, or they might attempt to adjust your seating; however, that is not guaranteed, so some pre-planning is important.

Smooth-Travel Tips with Your Dog

Whether it’s United or any other airline, these tips will help:

1. Choose your seat wisely

  • Window seats are better with small pets.
  • With a service dog, you’ll need to manage the aisle space (but don’t block the aisle).

2. Carry the essentials

  • Wipes
  • Pee pads
  • Water bottle + small bowl
  • Treats (limited)
  • Extra leash

3. Exercise before the airport

  • Walk your dog before the flight so that:
  • Stress is reduced
  • Energy is released
  • They remain calm during the flight

4. A dog should not be aggressive/disruptive.

If the dog is aggressive or not under control, the airline may refuse to board it.

Conclusion

To travel with United Airlines, you need to identify whether the animal is an ESA, a trained service dog, or a simple pet. United allows only trained service dogs, but they need to stay calm, be well-behaved, and under control in public places and during the flight. ESAs are no longer treated as a special category by United, and now they usually fall under the normal pet policy. If you are flying with a pet in the cabin, you will need an approved carrier, you will have to pay the pet fee, and seats for pets may be limited, so booking early is a good idea.
