The rules changed in 2021. Airlines are no longer required to accommodate ESAs. Here's what that means for you - and the one documentation type that still works.

The 2021 DOT rule removed ESA airline accommodation requirements. Only trained PSDs retain in-cabin access rights.
What Changed: The 2021 DOT Rule
In January 2021, the US Department of Transportation issued a final rule allowing airlines to treat emotional support animals as pets rather than service animals. This means:
Airlines are no longer legally required to accommodate ESAs in the cabin
ESA letters no longer grant in-cabin access on any major US carrier
Most major airlines (Delta, United, American, Southwest, JetBlue) no longer accept ESAs in cabin regardless of documentation
ESAs may still travel as checked pets or in-cabin pets where permitted by airline policy (fees and breed/size/species restrictions apply)
This is not a loophole. It is federal law. ESA letters - whether issued before or after 2021 - do not entitle you to in-cabin access on US airlines.
The Only Documentation That Still Works: Psychiatric Service Dog Letter
A Psychiatric Service Dog (PSD) is fundamentally different from an ESA:
ESAPsychiatric Service Dog
Task training required?✗ No✓ Yes - specific psychiatric tasks
Airlines required to accommodate?✗ No✓ Yes - under DOT guidelines
Housing (FHA) protection?✓ Yes✓ Yes
Public access (ADA)?✗ No✓ Yes
Letter required?✓ Yes (FHA only)✓ Yes (PSD letter)
Note: Your dog must be trained to perform a specific task that mitigates your psychiatric disability. The ADA permits owner-training - your dog does not need to be professionally trained.
What Airlines Require for Psychiatric Service Dogs in 2026
Under the 2021 DOT rule, airlines may require:
1
DOT Service Animal Air Transportation Form
Completed by a licensed mental health or medical professional confirming your psychiatric disability and the dog's role in mitigating it.
2
Relief attestation form
Confirmation that your dog can relieve themselves without incident during a long flight.
3
Behavior attestation
Confirmation that your dog will behave appropriately in an aircraft cabin and will not pose a threat to other passengers.
The Supportive Pet's PSD letters include supporting documentation to satisfy airline forms. Our clinicians provide the medical portion of the DOT forms on request.
Traveling With an ESA (Non-Dog) in 2026
If your ESA is a cat, rabbit, bird, or other species:
No US airline currently accommodates non-dog ESAs in the cabin under service animal provisions
Your animal may travel as a carry-on pet (cats, small dogs) or cargo, subject to airline policies and fees
Species not permitted as carry-on or checked pets cannot travel in-cabin under any documentation
For housing rights: Your ESA letter remains fully valid. The 2021 DOT rule only affects air travel - it did not change FHA housing protections. Learn about your housing rights →
ESA Air Travel FAQ
Can I fly with my emotional support animal in 2026?
Airlines are no longer required to accommodate ESAs under the 2021 DOT rule. Your ESA letter does not grant in-cabin access on US airlines. Your options are: travel with your ESA as a regular carry-on or checked pet (if permitted by airline policy), or obtain a Psychiatric Service Dog letter if your dog is task-trained for a psychiatric disability.
Which airlines still accept ESAs in 2026?
No major US airline is legally required to accept ESAs, and none of the major carriers (Delta, United, American, Southwest, JetBlue, Alaska) currently offer ESA accommodations. Some regional carriers may have limited exceptions - check directly with the airline before booking.
Do I need a PSD letter to fly with my dog?
If your dog is a trained psychiatric service dog and you want cabin access, you will need documentation satisfying the airline's service animal requirements - typically a licensed clinician's PSD documentation and the DOT Air Transportation Form. The Supportive Pet can provide the clinical portion of this documentation.
Can I get an ESA letter for international flights?
International flight rules vary by country and airline. Most international carriers follow their own national regulations. The 2021 DOT rule only governs US carriers. Check with your specific international carrier before traveling.
My ESA letter worked before 2021 - why won't it work now?
The 2021 DOT rule change removed airlines' obligation to accommodate ESAs regardless of documentation. Your letter is still valid for housing purposes under the Fair Housing Act - it simply no longer confers air travel rights. Only trained psychiatric service dogs with appropriate documentation retain in-cabin access rights.
Does my housing ESA letter still protect me?
Yes, absolutely. The 2021 DOT rule only affects air travel - it has no impact on your Fair Housing Act rights. Your ESA letter fully protects your right to live with your emotional support animal even in no-pet housing, and landlords cannot charge pet fees or deposits.
