Key facts at a glance
What the DOT rule actually changed
Before 2021, the Air Carrier Access Act required airlines to accommodate emotional support animals in the cabin at no charge if you provided a letter from a licensed mental health professional. The system was widely abused, and incidents involving untrained animals in aircraft cabins increased sharply. Delta alone reported an 84 percent increase in onboard animal incidents between 2016 and 2019.
On December 10, 2020, the DOT published a final rule that narrowed the ACAA's definition of "service animal" to match the ADA's definition: a dog individually trained to do work or perform tasks for a person with a disability. Providing emotional support through companionship does not qualify as work or tasks under this definition. As of January 11, 2021, airlines are not required to recognize ESAs as anything other than pets, and every major US carrier stopped doing so.
An ESA letter presented at check-in will be declined. You will be directed to the airline's standard pet policy. If your animal fits in an approved under-seat carrier and you pay the per-segment pet fee (typically $95–$150 each way), it may travel in cabin as a pet. If it does not fit, it does not fly in the cabin, regardless of any documentation you carry.
This is the part most people get wrong. A reviewed plan makes sure you don't.
What still works: the psychiatric service dog route
The DOT rule preserved full cabin access for psychiatric service dogs. A psychiatric service dog is not an ESA. The difference is task training. An ESA provides comfort through its presence. A psychiatric service dog is individually trained to perform specific disability-related tasks: interrupting a panic attack, reminding a handler to take medication, providing tactile stimulation to manage a dissociative episode. The task must be trained, not spontaneous.
If your dog is trained to perform tasks for a documented mental health condition, it qualifies as a psychiatric service dog under both the ADA and the ACAA, and it retains free cabin access on all US airlines. You will need to complete the DOT Service Animal Air Transportation Form and submit it to your airline at least 48 hours before departure. The DOT does not require professional training. Handler-trained service dogs qualify if the dog reliably performs the task and behaves appropriately in public.
Current fees by major airline (2026)
| Airline | ESA treatment | In-cabin pet fee |
|---|---|---|
| Delta | Standard pet | $95/segment |
| American | Standard pet | $150/segment |
| United | Standard pet | $150/segment |
| Southwest | Standard pet | $125/segment |
| JetBlue | Standard pet | $125/segment |
| Alaska | Standard pet | $100/segment |
International flights
The 2021 DOT rule applies to all flights departing from or arriving at a US airport, including foreign airlines on those routes. A flight from London to New York on British Airways falls under the DOT rule for the transatlantic leg. British Airways' own domestic flights within the UK follow UK rules, which do not recognize ESAs at all. Most European carriers do not accept emotional support animals under any classification. Check directly with your specific carrier for routes outside the US.

Frequently asked questions
Only if it fits inside an airline-approved under-seat carrier and qualifies as a standard cabin pet. It will not receive free cabin access, a fee waiver, or any accommodation beyond what the airline gives a regular pet.
No, not for flights. ESA letters lost legal standing for air travel under the 2021 DOT rule. They still matter for housing under the Fair Housing Act, but airlines are not required to recognize them.
A psychiatric service dog is individually trained to perform specific tasks for a person with a mental health disability, such as interrupting a panic attack or retrieving medication. Because it performs task-based work, it qualifies as a service animal under both the ADA and the ACAA and retains free cabin access on all US airlines.
It applies to all flights that depart from or arrive at a US airport, including flights operated by foreign carriers on those routes. Foreign airlines on domestic routes outside the US follow their own country's rules, which are often stricter.
