JetBlue Pet Policy: Fees, Carrier Rules & Service Animal Requirements

JetBlue's pet policy allows small dogs and cats to fly in the cabin — not as checked baggage or cargo — on most domestic and select international routes, for a per-pet fee, inside an airline-approved carrier that fits under the seat in front of you. As of August 2026, JetBlue caps the combined weight of pet and carrier at 20 pounds, limits carrier dimensions to 17 x 12.5 x 8.5 inches, and excludes Mint, exit-row, and bulkhead seating. Trained service dogs fly free under a separate federal rule, but emotional support animals do not qualify for that exemption.

JetBlue Pet Policy at a Glance

The table below summarizes JetBlue Airways' current in-cabin pet rules, drawn from JetBlue's official Traveling with Pets help page and corroborating pet-travel guides.

Who Can Fly With JetBlue as a Pet

JetBlue's cabin pet program is limited to small dogs and cats. According to JetBlue's official help page, the airline accepts “only small dogs and cats” in the cabin, and large dogs are not accommodated in any capacity. There is no cargo hold option for pets on JetBlue — if an animal doesn't fit the in-cabin carrier limits, it cannot travel on JetBlue at all, unlike airlines that offer a separate pet cargo program.

Pets must be at least 8 weeks old for domestic travel. For international itineraries, the animal must also meet the minimum age and documentation requirements of the destination country, which can be stricter than JetBlue's own minimum.

Carrier Requirements

JetBlue requires an FAA-compliant carrier that fits entirely under the seat in front of the traveler. Per JetBlue's official policy:

• Maximum outer dimensions: 17" L x 12.5" W x 8.5" H
• The carrier must be leak-proof and well ventilated
• The pet must be able to stand up and turn around comfortably inside
• Only one pet per carrier is allowed
• Combined pet and carrier weight cannot exceed 20 pounds
• The carrier counts as your personal item, taking the place of a bag under the seat

Your pet must stay zipped inside the carrier both at the airport and for the entire flight — JetBlue's policy states the animal “must remain inside the zipped pet carrier while at the airport and on the plane.”

JetBlue Pet Fees and Booking With JetPaws

JetBlue calls its pet-travel program JetPaws. Multiple pet-travel guides, including CitizenShipper (2026), report a fee of $125 per pet, per direction, which is non-refundable and charged on top of your ticket price. A round trip would run roughly $250 in pet fees under that figure. Because airline ancillary fees change without much notice, confirm the exact current amount directly with JetBlue when you book rather than relying solely on third-party guides.

How to Book a Pet on JetBlue

1. Add your pet during online booking or by calling JetBlue reservations, since pet spots are limited per flight and must be reserved in advance.
2. Pay the per-pet fee at booking; a second pet requires a second paid seat and a second fee.
3. Choose a Main Cabin or Comfort Plus seat — avoid exit rows, bulkhead rows, and Mint, which JetBlue restricts for pet carriers.
4. Check in online up to 24 hours before departure if you'd like, but you still must visit the airport counter.
5. At the airport, visit the full-service counter or speak with a crewmember in the self-service lobby to receive your JetPaws bag tag, which attaches to the carrier.
6. Keep your pet zipped in the carrier through security and boarding, and stow it under the seat in front of you for the flight.

Where Pets Cannot Sit

JetBlue prohibits pet carriers in several parts of the cabin. Per the airline's official policy, pets cannot occupy emergency exit rows, bulkhead seats, or Mint (business class) seats — Mint's seat configuration doesn't leave room for an under-seat carrier, and exit-row and bulkhead passengers must keep the area clear for safety reasons. If you book one of these seat types with a pet, expect to be reassigned at check-in or the gate.

Emotional Support Animals vs. Service Animals on JetBlue

This is the area travelers most often get wrong, and the rules changed nationally in 2021. The U.S. Department of Transportation's final rule on Traveling by Air With Service Animals, published in the Federal Register on December 10, 2020, redefined a service animal for air travel purposes as a dog individually trained to perform tasks for a person with a disability — and explicitly removed emotional support animals from that definition (U.S. Department of Transportation, 2020). Under the rule, animals that provide comfort just by their presence, without task-specific training, must fly as ordinary pets, subject to the airline's standard carrier rules and fees.

JetBlue's own pre-2021 policy, announced in a June 2018 investor release, had already tightened its emotional-support and psychiatric service animal program to dogs, cats, and miniature horses, backed by three forms submitted 48 hours in advance (JetBlue Airways, 2018). That 2018 ESA framework predates the DOT's 2021 rule and has since been superseded: JetBlue, like other major U.S. carriers, now treats emotional support animals as regular pets rather than a distinct free-flying category (The Points Guy, 2018; U.S. Department of Transportation, 2020).

Trained service dogs still fly in the cabin at no charge and are not subject to the pet fee or carrier-size limits. To fly with one, the handler must submit the DOT Service Animal Air Transportation Form confirming the dog's training, vaccination status, and behavior — JetBlue requests this generally at least 48 hours before departure for reservations booked that far ahead. Service dogs must be harnessed, leashed, or otherwise tethered and under the handler's control at all times, in the airport and on board.

Service Animal vs. Emotional Support Animal on JetBlue

Flying Internationally or to the Caribbean With a Pet

JetBlue's in-cabin pet program extends to select international and Caribbean routes, but destination-country rules layer on top of JetBlue's own policy. JetBlue's official guidance specifically notes that “Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets” (JetBlue, 2026), even though both are served as domestic-style routes. Other international destinations set their own vaccination, microchip, and import requirements independent of the airline, and some international routes exclude in-cabin pets entirely. Because these rules vary by country and change periodically, confirm requirements directly with JetBlue and the destination country's animal-import authority well before departure — JetBlue recommends starting the process at least 30 days ahead for international trips.

Does Animal Passport Replace JetBlue's Pet Paperwork?

No — and it's worth being precise about this, because the two are easy to conflate. JetBlue's pet policy governs airline carriage: fees, carrier dimensions, seating restrictions, and (for service dogs) the federal DOT form. Animal Passport is a different kind of product: a phone-based digital identity record built around muzzle biometrics, since a nose print is unique to an individual animal much like a human fingerprint. An Animal Passport record binds an owner to their animal along with breed, an estimated age generated from a dental photograph with a confidence score, a body condition score from 1–5 based on a side-profile photo, and vaccination history the owner logs.

That record is not a government-issued travel document, and it is not currently accepted by JetBlue or any airline in place of a carrier, a pet fee, or the DOT Service Animal Air Transportation Form. Its proven use case so far has been different: during livestock flood rescue efforts in Pakistan in August 2025, the biometric ID let farmers reclaim animals after paper ear tags had washed away. For a pet owner, that same idea — a durable, tamper-resistant identity record independent of a physical tag — is a useful complement to (not a substitute for) whatever documentation JetBlue and your destination country require.

Frequently Asked Questions

Does JetBlue allow pets in the cabin?

Yes. JetBlue allows one small dog or cat per carrier in Main Cabin or Comfort Plus seating, for a per-pet fee, as long as the carrier fits under the seat in front of the traveler (JetBlue, 2026).

How much does JetBlue charge to bring a pet?

Pet-travel guide CitizenShipper (2026) lists JetBlue's in-cabin pet fee at $125 each way. The fee is non-refundable and charged in addition to your airfare, so confirm the current amount when you book.

What size carrier does JetBlue require?

JetBlue caps carriers at 17" L x 12.5" W x 8.5" H, and the combined weight of the pet and carrier cannot exceed 20 pounds (JetBlue, 2026).

Can I bring my pet in JetBlue Mint or first class?

No. JetBlue does not permit pet carriers in Mint (business class) seating, exit rows, or bulkhead rows, because those seats lack the required under-seat storage space (JetBlue, 2026).

Does JetBlue accept emotional support animals?

No, not as a distinct free-flying category. Since the U.S. Department of Transportation's 2021 service-animal rule, JetBlue treats emotional support animals as ordinary pets subject to standard carrier rules and fees (U.S. Department of Transportation, 2020).

What is the DOT Service Animal Air Transportation Form?

It's the federal form handlers of trained service dogs submit to the airline confirming the dog's training, vaccination, and behavior. JetBlue generally requests it at least 48 hours before departure.

Can I fly internationally with my pet on JetBlue?

Yes, on select routes, but destination-country rules apply on top of JetBlue's cabin policy. Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets even though they're domestic-style JetBlue routes (JetBlue, 2026).

Does JetBlue transport pets as checked baggage or cargo?

No. JetBlue only carries small pets in the cabin and does not operate a pet cargo program, so animals that exceed the carrier and weight limits cannot fly with JetBlue at all.
