Can You Fly With an Emotional Support Animal in 2026?

The short answer for 2026 is that your emotional support animal flies as a pet, not as a support animal. On US airlines, the special access ESAs used to have is gone, and it's been gone long enough that the practical path now is to plan as if your dog is a regular pet. If you've been counting on an ESA letter to bring your dog into the cabin, this is the post to read before you book.

What changed

In 2021, the US Department of Transportation rewrote its rules and stopped treating emotional support animals as service animals for air travel. Airlines are no longer required to accept them in the cabin, and the ESA letters that used to do the job aren't recognized anymore. Every major US airline now applies its standard pet policy to ESAs. You can read the rule itself on the DOT's official page.

What that means in practice

Flying with your ESA now looks exactly like flying with any pet. If your dog is small enough to fit in a carrier under the seat, they ride in the cabin for the standard pet fee, usually somewhere around $95–150 each way, with a reservation made when you book. If they're too big for the under-seat carrier, they travel in the hold. Which side of that line your dog is on is the whole question, and I break it down in the cabin-vs-cargo post.

Service dogs are a separate category

The one category that still gets cabin access regardless of size is a trained service dog — a dog individually trained to perform tasks for a person with a disability. Psychiatric service dogs fall under this too. The emotional support type, where a dog's presence and comfort were enough on their own, is the part that's no longer recognized for the cabin.

Whichever category your dog falls into, two things make travel go smoothly, and both are worth putting real work into. The first is some training. A dog that knows how to settle, stay, and ride calmly in a carrier handles the airport and the flight far better than one who doesn't, and that training is the best gift you can give a dog who's going to fly. The second is keeping your dog steady on the day itself. A calm, well-behaved dog has an easy trip, and airlines can turn away a dog that's agitated or acting out at the gate. Time spent settling your dog before you travel pays off more than anything else once you're there.

International flights

Outside the US it varies by airline and destination country, but most foreign airlines also treat ESAs as pets, with their own size limits and fees. And the country you're flying into doesn't care about ESA status at all — your dog still needs the microchip, rabies vaccination, and health certificate that any pet needs, plus whatever that destination requires. I cover that side in the requirements post.

If you're a nomad traveling with an ESA

The good news is that "plan as a pet" is a completely workable plan, and it's the same one the rest of us use. Get a carrier that meets under-seat limits if your dog is small, never sedate them for the flight — here's why — and put the weeks in on crate comfort instead, which does more for an anxious dog than any letter ever did. The crate training post has that routine.

What this adds up to

Plan your dog's travel the way you would for any pet, and it gets a lot clearer. A small dog flies in the cabin; a bigger one goes in the hold. And if the hold isn't something you want to put a bigger dog through, flying isn't your only option — driving, trains, ferries, and in-cabin charters all work, and I go through them in traveling with a dog without flying. Either way, your dog comes with you. The full picture of flying internationally with a dog is in the main guide.
