United Airlines was once one of the few major carriers that allowed emotional support animals (ESAs) to travel in the cabin for free. However, after the U.S. Department of Transportation (DOT) updated its guidelines in 2021, United changed its policy. Under the new rules, airlines are no longer required to recognize emotional support animals as service animals. As a result, United no longer accepts ESAs as service animals, and they are treated as pets unless they meet the criteria for a trained service dog.t.
Understanding United Airlines’ Emotional Support Animal Policy
Until early 2021, emotional support animals could fly for free in United’s cabin with a letter from a licensed mental health professional. Passengers could bring dogs, cats, rabbits, and even miniature horses depending on the situation. But due to safety, misbehavior incidents, and growing misuse of ESA regulations, DOT made a regulatory change.
United Airlines updated its policy accordingly. Here’s what it means today:
-
Emotional support animals are no longer recognized as service animals.
-
They must travel as pets, following standard pet-in-cabin or pet cargo rules.
-
Only trained service dogs are allowed to fly in the cabin for free.
-
Cats, rabbits, birds, and all other animals are not eligible for service-animal status.
If you were hoping to bring your ESA in the cabin without paying a fee, United’s current rules unfortunately do not allow that. However, you still have options depending on the size of your animal, breed, health, and your flight route.
Difference Between ESAs and Service Animals on United
Many travelers confuse emotional support animals with psychiatric service dogs (PSDs). United treats them very differently.
Emotional Support Animals (ESAs):
-
Provide comfort or psychological relief
-
Do not require specialized training
-
Not considered service animals
-
Travel as pets only
-
Subject to all fees and carrier size rules
Service Dogs (Trained or Psychiatric Service Dogs):
-
Specifically trained to perform tasks for a disability
-
Recognized by United under DOT rules
-
Fly in the cabin for free
-
Require forms confirming training and behavior
If your dog performs trained tasks related to your mental health condition—such as interrupting panic attacks, grounding during dissociation, or detecting anxiety spikes—it may qualify as a psychiatric service dog, which United does accept.
But if your dog merely offers emotional comfort, companionship, or affection, it’s considered an ESA and must follow pet rules.
Can I Still Bring My ESA on United Flights?
Yes—you can bring your emotional support animal on United, but only as a pet.
This means:
-
You must pay United’s pet fee.
-
Your ESA must fit inside a pet carrier.
-
The carrier must fit under the seat.
-
Your ESA must remain inside the carrier for the entire flight.
United only allows small cats and dogs in the cabin. Larger ESAs must be transported as cargo (with exceptions for embargoed destinations and certain breeds).
United Airlines Pet-in-Cabin Policy for Emotional Support Animals
Because ESAs count as pets, the standard pet-in-cabin rules apply:

-
Small dogs
-
Small cats
Age Requirement:
-
Minimum 2 months old for domestic flights
-
Minimum 4 months old for international flights
Pet Carrier Requirements:
-
Hard-sided carrier: maximum 17.5 x 12 x 7.5 inches
-
Soft-sided carrier: can be slightly larger as long as it fits under seat
-

-
Pet must remain fully in the carrier
Pet Fee:
-

If your ESA is too large or does not fit comfortably in a carrier placed under your seat, it cannot fly in the cabin.
United Cargo Options for Larger Emotional Support Animals
Large dogs, breed-restricted pets, and oversized ESAs must travel as cargo through United’s PetSafe Program, though this program is sometimes restricted due to weather or operational constraints.
PetSafe Program Rules:
-
Not available on all flights
-
Not available for brachycephalic (snub-nosed) dogs and cats
-
Requires advanced booking
-
Prices vary depending on route and animal size
-
Requires health certificate
-
Restricted during extreme weather seasons
Cargo travel is often more stressful for animals, so passengers with ESAs should weigh the pros and cons carefully before booking.
International Travel With Emotional Support Animals on United
International routes follow stricter guidelines.
Some countries do not allow pets (including ESAs) to enter without quarantine or detailed medical documentation.
Examples of destinations with stricter pet regulations:
-
Australia
-
New Zealand
-
United Kingdom
-
Hawaii (U.S. state but has its own strict rules)
In many cases, ESAs traveling as pets may:
-
Be banned entirely
-
Require 30+ days advance documentation
-
Undergo quarantine
-
Require microchips, vaccines, and rabies titers
Passengers are responsible for researching and meeting all entry and exit requirements.
Does United Require Documentation for ESAs?
Since emotional support animals are no longer considered service animals, United does not accept ESA letters. No mental health documentation is needed or accepted.
The only required documents are:
-
Standard pet vaccination records
-
Health certificate for some destinations
-
Proof of rabies vaccine
For cargo travel, additional paperwork may be required, including:
-
Veterinarian health certificate
-
Temperature acclimation form
-
Breed verification
Remember: Submitting a fake ESA as a trained service dog is illegal and can result in fines or bans.
United Airlines Service Dog Policy (Not ESAs)
United still accepts trained service dogs, including psychiatric service dogs. If your dog is trained to perform tasks, you will need:
-
DOT Service Animal Air Transportation Form
-
DOT Service Animal Relief Form (for flights 8+ hours)
Required statements include:
-
The dog is trained to behave in public
-
The dog performs tasks related to a disability
-
The handler accepts responsibility for animal behavior
United staff may deny boarding if the dog:
-
Shows aggression
-
Lacks proper training
-
Appears unhealthy
-
Violates safety standards
This policy does not apply to emotional support animals.
Why Did United Stop Allowing Emotional Support Animals?
Multiple reasons led major airlines—including United—to stop allowing ESAs for free:
1. Safety Issues
Airlines reported increases in biting incidents, disruptions, and untrained animals.
2. Policy Misuse
Passengers claimed turtles, peacocks, pigs, hamsters, and even kangaroos as ESAs to avoid pet fees.
3. DOT Regulation Change
In 2021, the DOT officially declared that ESAs are not service animals and airlines no longer have to accommodate them.
4. Inconsistency with International Rules
Foreign airports often had stricter rules, complicating operations for airlines.
United’s updated policy aligns with the new federal guidelines and industry standards.
Tips for Traveling With Your Emotional Support Animal on United

Final Thoughts on Flying With an Emotional Support Animal on United
While United Airlines no longer recognizes emotional support animals as service animals, you still have options to bring your pet on board—just not under the old ESA designation. ESAs must now follow the airline’s pet rules, including carrier size limits, fees, and seating restrictions.
Understanding the difference between ESAs and trained service dogs is critical. If your dog performs disability-related tasks, they may qualify as a service dog and fly for free. If they simply offer comfort or companionship, they will be treated as a pet.
Traveling with an ESA may require more planning than before, but with preparation and familiarity with United’s policies, you can still ensure a smooth and comfortable journey for both you and your animal.
