ESA letter for travel

The Department of Transportation updated its Air Carrier Access Act rules through a final rule published December 10, 2020, which took effect January 11, 2021. The definition in 14 CFR 382.3 limits service animals to dogs, of any breed or type, that have individual training to work or carry out tasks for someone with a disability.

For air travel, the rule places emotional support, comfort and companionship animals outside the service animal category, along with dogs still being trained. Airlines can classify ESAs as pets. Nothing stops an airline from flying them at no charge, but none is obligated to.

In practice, most travelers now fly with their emotional support animal under the airline's pet policy. Those policies vary by airline and route, so check directly with your carrier before you book.

• Pet-in-cabin programs usually allow small cats and dogs in an approved carrier that fits under the seat in front of you.
• Expect a pet fee each way and a limit on how many pets are allowed in the cabin per flight, so reserve early.
• Larger animals may need to travel as checked or cargo pets, if the airline offers it, with temperature and breed restrictions.
• International trips and some U.S. destinations have their own health certificate, vaccination or import rules.

A psychiatric service dog has individual training to carry out specific tasks connected to a mental health disability. The ADA's own examples include prompting someone to take their prescribed medication and helping calm a person with PTSD in the middle of an anxiety attack. Just being there and offering comfort isn't a task.

The DOT rule puts psychiatric service dogs on equal footing with all other service dogs. An airline can ask for DOT forms covering the dog's health, how it behaves and how it was trained, plus, when a flight lasts eight hours or longer, a form about how the dog will relieve itself. Beyond that, airlines can't ask for other paperwork unless another government's animal rules require it. Letters from mental health professionals are no longer part of the process.

It matters to be truthful about which category your animal belongs in. Many states penalize people who falsely claim an untrained pet has service animal status.

Hotels and other places of public accommodation follow the ADA, which covers trained service dogs but not emotional support animals. A hotel can apply its normal pet policy to an ESA, including fees or a no-pet rule.

Vacation and short-term rentals can be more complicated, and state laws vary. Ask about pet policies before you book.

We write our ESA letters for housing. They back up a reasonable accommodation request under federal fair housing law, which may require landlords to consider setting aside pet rules. Even in housing, guidance HUD released in May 2026 means each untrained ESA request gets an individual review.

If you're moving and your animal will travel with you, the letter is useful once you arrive and apply for a new home. It won't change how an airline treats your animal.

Travel can be stressful for you and your animal. A little planning helps both of you feel calmer.

• Book your animal's spot when you book your own ticket.
• Get your pet used to its carrier in the weeks before the trip.
• Visit your veterinarian about fitness to fly and any required paperwork.
• Pack water, food, waste bags and a familiar blanket or toy.
• Have a plan for managing your own symptoms, such as breathing exercises or support contacts.

If you're relocating, plan your animal's trip and your housing request together. Ask about pet policies early, and send your accommodation request to the new landlord before move-in so there's time to answer questions. Remember that state ESA laws differ, so check the guide for the state you're moving to.

If travel brings on anxiety or panic, ask your therapist about coping strategies you can use while you're away. Should you ever be in crisis in the U.S., dial or text 988; in an emergency, dial 911.
