If you're planning to fly with your emotional support animal, you need to know that the rules changed dramatically in 2021 — and the landscape continues to shift. Here's an honest look at where things stand.
What Changed in 2021?
On January 11, 2021, the U.S. Department of Transportation (DOT) finalized a rule that amended the Air Carrier Access Act (ACAA). The key change: airlines are no longer required to accommodate emotional support animals in the cabin.
Before this rule change, the ACAA required airlines to allow ESAs to fly in the cabin free of charge, provided the passenger had a valid ESA letter. This led to well-publicized incidents involving unusual animals (peacocks, pigs, miniature horses) and a sharp increase in ESA-related complaints from other passengers, flight crews, and people with trained service animals.
The 2021 rule reclassified ESAs. Under the updated ACAA:
- Service animals (specifically, dogs trained to perform tasks for a person with a disability) must still be accommodated in the cabin at no charge
- Emotional support animals are no longer recognized as service animals under the ACAA
- Airlines may treat ESAs as pets, subject to pet policies, pet fees, breed restrictions, and carrier requirements
This was a significant loss of protection for ESA owners who relied on air travel accommodations.
Can You Still Fly with Your ESA?
Technically, yes — but under pet policies, not disability accommodations. Here's what that means in practice:
As a pet. Most major airlines allow small dogs and cats in the cabin in an approved carrier, for a fee (typically $95-$150 each way). Your animal must fit under the seat in a carrier. Weight limits vary but usually cap around 20 pounds including the carrier.
This means larger ESAs face significant barriers. If your ESA is a medium or large dog, in-cabin travel is generally not an option under pet policies. You would need to use cargo transport, which is stressful for animals and comes with its own risks and costs.
Current Airline Policies for ESAs (2026)
The major U.S. airlines have aligned with the DOT rule and no longer recognize ESAs for free cabin travel. Here's the current state:
| Airline | ESA Policy | Pet Policy | |---|---|---| | American Airlines | ESAs treated as pets | Small dogs/cats in cabin, $150 each way | | Delta Air Lines | ESAs treated as pets | Small dogs/cats in cabin, $95 each way | | United Airlines | ESAs treated as pets | Small dogs/cats in cabin, $150 each way | | Southwest Airlines | ESAs treated as pets | Small dogs/cats in carrier, $125 each way | | JetBlue | ESAs treated as pets | Small dogs/cats in cabin, $125 each way | | Alaska Airlines | ESAs treated as pets | Small dogs/cats in cabin, $100 each way |
Fees and policies change frequently. Always check the airline's current pet policy before booking.
International carriers may have different rules. Some airlines outside the U.S. still recognize ESAs under their own policies. If you're flying internationally, check the specific airline's policy and the destination country's animal import requirements.
The Psychiatric Service Dog Alternative
If you have a mental health condition like PTSD, severe anxiety, or depression, there is a path to protected air travel with an animal: a psychiatric service dog (PSD).
A psychiatric service dog is trained to perform specific tasks related to a psychiatric disability. Unlike an ESA, which provides comfort through companionship alone, a PSD must be trained to do something active — such as:
- Performing deep pressure therapy during a panic attack
- Alerting to oncoming anxiety episodes
- Grounding the handler during a dissociative episode
- Interrupting self-harmful behaviors
- Creating physical space in crowded environments
Because PSDs are classified as service animals under both the ADA and the ACAA, airlines must accommodate them in the cabin at no charge. The handler must complete the DOT's Service Animal Air Transportation Form, which includes attestations about the dog's training and behavior.
This is not a loophole. A psychiatric service dog requires genuine task training and the handler must have a qualifying disability. Misrepresenting a pet or ESA as a service animal is illegal under federal law and several state statutes.

What Documentation Do Airlines Require for Service Animals?
If you're flying with a trained psychiatric service dog, you'll need:
-
DOT Service Animal Air Transportation Form. This form requires you to attest that your animal is a trained service animal, that it's trained to perform tasks related to your disability, and that it will behave appropriately in the aircraft cabin. Most airlines require this form to be submitted 48 hours before departure.
-
DOT Service Animal Relief Attestation Form. For flights over 8 hours, you must attest that the animal either won't need to relieve itself or can do so in a sanitary manner.
-
Health and vaccination documentation. While not always required by the airline, having current vaccination records and a health certificate from your veterinarian is strongly recommended.
Airlines cannot require documentation about your specific disability, your medical records, or proof of the animal's training. They can, however, assess the animal's behavior. A service dog that is aggressive, disruptive, or not under the handler's control can be denied boarding or removed from the aircraft.
Tips for Traveling with Your Animal
Whether you're flying with a service dog or bringing your ESA as a pet, these tips will make the process smoother:
Book early and notify the airline. Let the airline know you're traveling with an animal when you book, or at least 48 hours before your flight. For service dogs, most airlines require advance submission of DOT forms.
Choose direct flights. Connections add stress for both you and your animal. Layovers mean navigating unfamiliar airports, finding relief areas, and reboarding.
Visit the vet before travel. Get a health certificate and make sure vaccinations are current. Some destinations require specific vaccinations or quarantine periods.
Bring supplies. Water bowl, waste bags, treats, and any medications your animal needs. Also bring copies of all documentation — airlines occasionally lose or misplace forms.
Practice the carrier. If your animal will travel in a carrier under the seat, practice at home. A stressed animal in an unfamiliar carrier at 35,000 feet is miserable for everyone.
Know the relief areas. Most major airports have designated pet relief areas, both pre-security and post-security. Check your airports' maps before you travel.
Advocacy and Legislative Efforts
Several advocacy organizations continue to push for restored ESA air travel protections. Bills have been introduced in Congress to reinstate some ACAA protections for ESAs, though none have passed as of early 2026.
In the meantime, some states have considered legislation requiring airlines to accommodate ESAs on flights within the state. These efforts face significant legal challenges because airline regulation is primarily federal.
The most practical path for ESA owners who need protected air travel is to explore whether a psychiatric service dog is appropriate for their condition — with genuine task training and proper documentation.
How PawClear Can Help
While PawClear's ESA registration does not grant airline access (no registration can — that's determined by federal law), our documentation packages help you keep your animal's records organized for any situation. If you need ESA documentation for housing purposes, register your ESA with PawClear starting at $59.95. For information about service animal registration, visit our service animal registration page.
