Airline policies
Every major US airline treats emotional support animals as pets. Here is what that means at the gate, and what to verify before you book.

Why every airline says no
The Department of Transportation's revised Air Carrier Access Act rule took effect in January 2021. It removed the requirement that airlines accommodate emotional support animals and narrowed the definition of a service animal to a dog individually trained to do work or perform tasks. Carriers moved to pet policies within weeks, and none has moved back.
What flying as a pet involves
| What to check | Typical range |
|---|---|
| In-cabin pet fee, each way | Roughly $95–$150 on US carriers |
| Carrier size | Must fit fully under the seat in front of you |
| Combined pet and carrier weight | Commonly capped around 20 lb |
| Animals per flight | Usually a small cap — book early |
| Animals per passenger | Usually one |
| Cargo | Varies by carrier and season; some have stopped it entirely |
| Snub-nosed breeds | Frequently barred from cargo for health reasons |
Verify with the airline before you book
Fees, weight caps and per-flight limits change, and they differ on codeshare and international segments. Check the airline's current pet policy page and call if anything is ambiguous. This page describes the general landscape, not any carrier's current terms.
Service dogs are different
A trained service dog flies in-cabin, free, and is not required to be in a carrier. What airlines can require:
- The DOT Service Animal Air Transportation Form, attesting to the dog's health, training and behavior. This is signed by you, not by a clinician — a common misunderstanding.
- For flights of eight hours or more, a relief attestation form.
- Submission up to 48 hours in advance if you booked more than 48 hours out.
- That the dog fit within your foot space and be harnessed or leashed and under control.
Airlines may limit you to two service dogs, and may refuse a dog that behaves aggressively. Psychiatric service dogs are treated the same as any other service dog under the current rule — the old requirement of extra mental health documentation was removed.
Practical advice
- Book the animal at the same time as your seat. Per-flight caps fill, and you can be denied boarding with a confirmed ticket.
- Non-stop where possible. Every connection is another chance for something to go wrong.
- Measure your carrier against the specific aircraft. Under-seat space varies by plane, and bulkhead rows often have none.
- Do not sedate without veterinary advice. Sedatives can be dangerous at altitude.
- Find the animal relief area in your connecting airport before you fly, not after you land.

About the PSD letter: it is documentation from a licensed clinician, not a certificate or an ID. Under the ADA, public access comes from your dog being individually trained to do work or tasks for your disability. Businesses are allowed to ask only two questions and are not allowed to require paperwork. Nobody can sell you access rights — anyone who says otherwise is selling a novelty.
You are charged only after a clinician approves you. We may place a temporary authorization hold on your card beforehand to confirm it is valid; a hold is not a charge and is released if you are not approved.
100% refund if your landlord denies your ESA. If your housing provider refuses the accommodation after you submit a letter we issued, we refund what you paid in full. Full terms, including what a claim needs, on our refund policy page.
Questions
Frequently Asked Questions
Is any airline still accepting ESAs?
No major US carrier does. A small number of international carriers have their own policies on some routes — verify directly with the airline, and do not rely on secondhand information for something that could strand you at a gate.
Can I bring my ESA letter to the airport anyway?
You can, and it will not change the outcome. Airline staff are applying a pet policy, and no letter overrides it.
What forms do I need for a service dog?
The DOT Service Animal Air Transportation Form, plus a relief attestation for flights of eight hours or more. Both are handler-attested. Download them from the DOT or the airline site and submit in advance.
