**In short:** None, as a special category: since January 2021, 14 C.F.R. § 382.3 has excluded emotional support animals from the service animal definition, so every U.S. airline carries them under its ordinary pet policy. What differs is the pet terms: species, combined weight, carrier size, per-flight caps and the fee, $150 each way domestically at Delta, United, American and JetBlue. Check your carrier's pet page and remaining slots before booking.

Search for an airline that takes emotional support animals and the results
will offer you lists, rankings and comparison tables, most of them written
as though some carriers had said yes and others no.

That is not the shape of the answer. Every U.S. airline treats an
emotional support animal the same way, because a federal rule tells them
to, and the differences between carriers are differences in **pet
policy**: weight, carrier size, price, how many animals fit on the
aircraft. Those differences are real and they decide whether your trip
works. They are just not what the question usually assumes.

## Why don't any airlines accept ESAs as service animals?

The definition at 14 C.F.R. § 382.3 does the work. A service animal, for
air travel, is "a dog, regardless of breed or type, that is individually
trained to do work or perform tasks for the benefit of a qualified
individual with a disability." And then, plainly: "Animal species other
than dogs, emotional support animals, comfort animals, companionship
animals, and service animals in training are not service animals for the
purposes of this part."

An airline that decided to give emotional support animals cabin access as
assistance animals would be inventing a category the regulation does not
have. The carriers say so themselves, and bluntly. United: "therapy and
emotional support cats and dogs must fly as pets, not service animals."
JetBlue answers the question "how big can emotional support animals be in
the cabin?" with a single sentence, **"We no longer accept emotional
support animals."**

So there is no carrier to find. There is a pet policy to fit into.

## What goes into an airline's pet policy for an ESA?

Five variables, and they matter in roughly this order.

**Species.** Most U.S. carriers accept small dogs and cats in the cabin.
Beyond that it thins out quickly, and a rabbit, bird or reptile that is a
perfectly good support animal at home is often simply not carried.

**Combined weight.** The number that counts is the animal plus the
carrier, not the animal. American publishes a 20 lb (9.07 kg) limit and
says outright that they "will weigh them at check-in", worth knowing
before you arrive with a 19 lb dog in a 3 lb bag.

**Carrier dimensions against a specific aircraft.** The constraint is the
space under the seat in front of you, which varies by fleet and by seat.
A carrier that flew last month may not fit next month on a different
aircraft.

**The per-flight cap.** This is the one that strands people. American
allows "a maximum of 20 pet carriers across all cabins" on a flight. When
those are gone, they are gone, regardless of what you have paid.

**The fee, per direction.** Delta publishes $150 for travel within the
U.S., Canada, Puerto Rico and the U.S. Virgin Islands, and $200 for
international itineraries. United publishes $150. American publishes $150
and $200 on the same split.

## What do major airlines charge to fly an ESA?

Airline pages are aggressive about blocking automated readers, and a
comparison table assembled from half-remembered figures is worse than no
table. So here is what was verified, with the date it was read.

| Carrier | Verified | Checked |
|---|---|---|
| Delta | $150 within U.S./Canada/PR/USVI; $200 international | live, 5 Sep 2026 |
| United | $150; ESAs and therapy animals carried as pets | archived page, 19 Aug 2026 |
| American | $150 / $200; 20 lb combined limit weighed at check-in; max 20 carriers per flight | archived page, 19 Aug 2026 |
| JetBlue | $150 each way; carrier max 17 × 12.5 × 8.5 in; one pet per carrier; **max 6 pets per flight**; none in Mint | live, 5 Sep 2026 |
| Southwest | Cats and dogs, cabin only, domestic only, from 8 weeks old; up to two same-species pets per carrier; fare refundable and paid at the ticket counter | live, 5 Sep 2026 |

Two things stand out from that table. **JetBlue caps a flight at six
animals** where American allows twenty: on a full JetBlue route the slot,
not the fee, is the binding constraint. And **Southwest is the outlier on
carrier occupancy**: it is the only one of the five that lets a single
carrier hold two animals, provided they are the same species.

Southwest publishes its pet fare on a separate charges page that could not
be read for this piece, so no Southwest figure appears above. **Alaska is
absent entirely**, its pet pages render their content in a way that
returned nothing readable on repeated attempts. Rather than reproduce
numbers from memory, both gaps are left as gaps. If another site gives you
a confident figure for all eleven U.S. carriers, ask yourself when it was
last checked.

Fees move, too. Delta dates its current domestic fee to tickets issued on
or after 8 April 2025. Any table, including this one, is a snapshot.

## How can you check your airline's pet policy?

The reliable method is unglamorous and it beats every comparison article,
including this one.

Go to the airline's own pet page, not a summary of it. Find four
numbers: the in-cabin fee for your **direction**, the combined weight
limit, the maximum carrier dimensions, and whether the animal must be
booked in advance. Then telephone and ask one question the page never
answers: **how many pet slots are left on that specific flight.**

Do that before you buy the ticket. Reservations staff can add an animal to
a booking; they cannot add capacity to an aircraft.

Two things to avoid while you are on the call. Do not describe an
untrained animal as a service dog to sidestep the fee, several states
criminalise the misrepresentation itself, and the saving is not worth it.
And do not offer an ESA letter as documentation. Section 382.75 caps what
a carrier may require at the DOT's own form for a trained service dog, and
a housing letter has no place in that system. An agent who declines to
read it is following the rule.

## What if your animal doesn't fit an airline's pet policy?

For a large dog, the honest answer is that the cabin is closed and the
remaining options are ground transport, boarding, or changing the
animal's category.

Only one of those is a legal change. A dog individually trained to do
work or perform tasks connected to a psychiatric disability meets the
§ 382.3 definition, travels in the cabin without a carrier, and cannot be
charged for. The distinction is task training rather than temperament: a
dog trained to interrupt a dissociative episode or perform deep pressure
therapy on cue is working, and a dog that helps by being present is not,
however much it helps.

That route costs months, not money.
[How to qualify for a psychiatric service dog](/blog/articles/how-to-qualify-for-a-psychiatric-service-dog/)
sets out the standard, and
[flying with a psychiatric service dog](/blog/articles/flying-with-psychiatric-service-dog/)
covers the form and the airport process.
[Flying with an emotional support animal](/blog/articles/flying-with-an-emotional-support-animal/)
covers the pet route end to end if that is the one you are taking.

## Where does your ESA letter still work?

Nothing above touches housing, and housing is where an assistance animal's
status does its real work. Under 24 C.F.R. § 100.204 a housing provider
must consider a reasonable accommodation for an assistance animal, which
is what opens a no-pets building and removes the pet charges attached to
it. The air travel rule and the housing rule have never shared a
definition, and the 2021 change to one did nothing to the other.

That is the asymmetry worth internalising. A letter from a licensed
provider who has actually assessed you is worth nothing at a boarding gate
and a great deal at a leasing office, every month, for as long as you rent.
If you have been putting off getting that assessment because you assumed
it covered flying, the assessment is still the thing to do. It was always
about the place you live.

Our clinicians are licensed in the state where you rent, and an evaluation
ends either with documentation that a housing provider has to engage with
or with an honest answer that it is not supported. Both are real outcomes,
which is what makes the first one worth having.

For the flight itself: book the animal when you book the seat, measure the
carrier rather than the dog, price both directions, and confirm the pet
count on your actual flight. That is the whole of the job, and no airline
on any list will do it for you.

## Frequently asked questions

### Which airlines still accept emotional support animals?

As a category with special status, none. Since the Department of Transportation's rule took effect in January 2021, 14 C.F.R. § 382.3 has excluded emotional support animals from the definition of a service animal, so every carrier covered by the rule books them under its ordinary pet policy. The question worth asking is not which airline accepts an ESA but which airline's pet terms your animal actually fits.

### Is there an airline that lets my ESA sit outside a carrier?

Not as an emotional support animal. Cabin travel outside a carrier is how a trained service dog flies, and 14 C.F.R. § 382.3 limits that category to a dog individually trained to do work or perform tasks. An animal travelling under a pet policy stays in a carrier that fits under the seat in front of you for the whole flight, on every U.S. carrier that publishes one.

### Do any airlines waive the pet fee for an ESA?

The fee is lawful and carriers charge it. Section 382.31(a) bars charging for accommodations the rule requires, then adds that a carrier "may charge for services that this part does not require." Carrying an emotional support animal is not required by part 382, so the fee sits outside the bar. Fee waivers, where they exist, are commercial decisions rather than obligations.
