Emotional Support Animal Airlines in 2026: Who Still Accepts ESAs, Region by Region
Last updated: October 2026. By Mia Sgarlato, founder of Pet Passport Club
If you're searching for emotional support animal airlines, here's the honest picture: the list got very short after 2021, and almost none of it applies to a flight that touches the US. A few Latin American carriers still accept ESAs on regional routes. Everyone else treats your ESA as a pet.
Short version: No US airline treats emotional support animals as service animals anymore, since the DOT's rule took effect in January 2021. The emotional support animal airlines left in 2026 are mostly Latin American (Avianca, LATAM, Volaris, Copa, and Aeroméxico domestically), with dog caps around 10 to 12 kg. LATAM and Volaris explicitly exclude US routes, so assume the rest won't help on a US flight unless they confirm in writing.
Who this is for: This is for US pet owners with an ESA who are planning international or regional flights and want to know what's actually still possible.
What Changed for Emotional Support Animals on US Airlines
The DOT announced its final rule in December 2020, and it took effect in early 2021. Under the DOT's service animal rules, a service animal is a dog individually trained to do work or perform tasks for a person with a disability. Emotional support animals are explicitly excluded.
What that means in practice:
US airlines can (and do) treat your ESA as a pet, with pet fees, carrier rules and size limits.
Trained psychiatric service dogs keep full service animal status.
Only dogs qualify. Cats and everything else are pets.
So American, Delta, United, Alaska and Southwest are off the list of emotional support animal airlines. There's no ESA category to book. Small dogs can still fly in-cabin as pets. That's how my mini dachshund Poppy flies, and it's the realistic path for most ESA owners now.
Airlines That Accept Emotional Support Animals, Region by Region
Here's where emotional support animal airline policies stand as of October 2026, based on airline pages where I could find them. Treat this as a starting point, since these policies change fast.

The takeaway: real emotional support animal airlines in 2026 are basically a Latin American regional thing, and the moment your route touches the US, you're back to pet rules or the psychiatric service dog process.
Latin America: Avianca, LATAM, Volaris and Copa
This is where emotional support animal airlines still exist. The Avianca emotional support dog page allows one ESA dog per passenger in a flexible carrier around 56 x 36 x 25 cm. Its documentation page says the one-year letter rule doesn't apply to US flights without saying what does. Get written confirmation before you book.
LATAM's emotional support page is clearer: the DOT doesn't recognize emotional support dogs, so trips from, to or via the US are out. Volaris also limits ESAs to Latin American routes, free if you meet the requirements.
US and Canada
WestJet stopped accepting ESAs in 2021, and Air Canada announced the same that year. But Air Canada also publishes ESA dog forms dated September 2024, so confirm with its accessibility team if it's on your route.
Europe and Spain
I lived in Valencia, so I get asked about Spanish carriers a lot. Neither Iberia nor Air Europa is on the list of emotional support animal airlines (both treat ESAs as pets), and LOT dropped them in 2021. Plan around the 8 kg cabin cap (carrier included) most European carriers use.
Asia and the Middle East
Qatar Airways doesn't accept ESAs in the cabin, and Singapore Airlines dropped them in 2023. ANA has an ESA form, but only for its Mexico City flights.
What a Valid Emotional Support Animal Airline Letter Needs
On the carriers that still say yes, the emotional support animal airline letter is the whole ballgame. Across Avianca, Volaris, Air Canada and ANA, the common thread is:
Letterhead with the professional's license type and number.
Signed by a licensed mental health professional (psychiatrist, psychologist, clinical social worker) or, for some airlines, a physician.
Dated within one year of your flight.
States your condition and that you're under their care, and that the dog needs to accompany you.
On the airline's own form if it has one (LATAM, Air Canada and ANA do).
About online letter mills: a letter sold after a 20-minute quiz isn't what these airlines describe. They want a professional who's actually treating you, and agents do question generic letters.
Psychiatric Service Dogs vs. ESAs
A psychiatric service dog is trained to perform specific tasks, like interrupting a panic attack. It qualifies as a service animal under DOT rules, and on US flights you'd complete the DOT Service Animal Air Transportation Form, which airlines can request up to 48 hours before travel.
An ESA provides comfort just by being there. That matters, but it isn't training. If your dog isn't task-trained, don't call it a service dog on a federal form.
How to Fly With an ESA in 2026, Step by Step
Map your full route. If any leg touches the US, plan on pet rules or the service dog process.
Confirm the emotional support animal airline policy in writing for your specific route.
Get a real letter from your treating provider, on the airline's form if it has one.
Book through the right channel (usually the contact center) at least 48 hours ahead.
Handle the destination's import rules. Rabies vaccine, microchip and health certificate apply no matter what the airline calls your dog.
Have a backup plan in case the counter denies the ESA request.
Common Mistakes With Emotional Support Animal Airline Policies
Assuming a foreign airline's ESA policy covers a flight to or from the US.
Buying an instant online letter and expecting it to hold up at check-in.
Forgetting that ESA status does nothing for the destination country's vaccine and health certificate rules.
Booking a big dog expecting cabin space when the airline caps ESAs at 10 to 12 kg.
Airline rules, letters and import paperwork are a lot to juggle at once. If you want someone to sort out which option fits your trip, we offer 1-hour consult calls for exactly this.
Emotional Support Animal Airlines FAQ
-
No. Since 2021, US airlines treat ESAs as pets. Small ones can still fly in-cabin under standard pet rules and fees.

Yes, for dogs. Avianca allows one ESA dog per passenger, booked 48+ hours ahead through its contact center, with a professional's letter. Dogs over 10 kg go in the hold. Confirm US routes before booking.
-
Not as an ESA from the US, as far as I can find. Volaris and LATAM exclude US routes, and Aeroméxico limits ESAs to domestic flights. Your dog can usually fly in-cabin as a pet.
-
A few. Volaris accepts ESA cats on eligible routes, and LATAM allows them on Colombia and Argentina routes in a carrier.
-
Usually not. Airlines that still accept ESAs want a dated letter from a professional who's treating you, sometimes on their own form.
-
A psychiatric service dog is task-trained and counts as a service animal under DOT rules. An ESA is treated as a pet on US flights.
Planning Your ESA Trip Without the Guesswork
The list of airlines that accept emotional support animals keeps shrinking, and the fine print (routes, weight caps, letter dates) is where trips fall apart. Flying as an in-cabin pet works fine for most small dogs once the paperwork is right.
If you'd like us to handle airline calls, checklists and timeline with you, our Co-Pilot Concierge tier is built for this, and our destination guides cover the import side for Mexico, Costa Rica, Hawaii and the EU.
The right paperwork is what gets your dog on the plane. Let's get it sorted.
