JetBlue Animal Policy (2026): What Pets and Service Animals Can Fly, Fees, Carriers and Routes

JetBlue's animal policy allows only small dogs and cats to fly as pets, and only in the cabin, inside an approved carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat in front of you. JetBlue carries no animals as checked baggage or cargo, allows six pets per flight, and bans pets from Mint and from flights to or from the UK and European Union. Trained service dogs fly free with a U.S. Department of Transportation form. The pet fee is reported at $150 each way as of September 2026.

The JetBlue animal policy is the set of rules JetBlue Airways publishes in its Traveling with Pets help page and its Contract of Carriage. Those rules decide which animals may board, how they must be contained, what they cost, and which routes are closed to them. This guide was last updated in September 2026 and uses JetBlue's own documents first, then U.S. federal sources.

JetBlue animal policy at a glance (September 2026)

Which animals can fly on JetBlue?

JetBlue accepts only small dogs and cats as pets. Its Traveling with Pets page states that no large dogs are accommodated, and its Contract of Carriage (version dated July 29, 2026) says that no animals may travel as checked baggage and that no animals other than small dogs and cats are allowed in the cabin.

That rules out birds, rabbits, ferrets, reptiles and any dog too large for an under-seat carrier. JetBlue also says it does not accept pet remains, cremated or otherwise, in the cabin or as cargo.

There is one narrow exception. The Contract of Carriage says that in certain cases, search and rescue dogs may be permitted to travel, and that a fee may apply.

Is there a weight limit?

JetBlue's current help page does not publish a weight limit, a minimum age or a breed restriction. The only stated physical test is that the pet fits in the carrier and can stand up and turn around inside it when it is closed. Some third-party guides cite a 20-pound limit for pet plus carrier, but that figure did not appear on the JetBlue pages reviewed for this article in September 2026.

JetBlue pet carrier rules

According to JetBlue's Traveling with Pets page (2026), the carrier must meet all of the following:

• No larger than 17 in long x 12.5 in wide x 8.5 in high (43.18 x 31.75 x 21.59 cm).
• Leak-proof bottom and good ventilation.
• Soft-sided or hard-sided carriers are both accepted.
• No containers that could allow escape.
• One pet per carrier, with room to stand up and move around.
• The pet and carrier count as your one personal item and must fit under the seat in front of you.

The 8.5-inch height is the number that disqualifies most carriers. A soft kennel bought to another airline's 11-inch recommendation will be too tall for JetBlue, a point the pet-relocation firm Pet Travel Advisors also made in its September 2026 review. JetBlue sells carriers at the JFK Terminal 5 ticket counter for USD $55, with limited quantities and credit card payment only.

Pets must stay inside the zipped carrier at the airport and on board. JetBlue allows you to unzip it briefly to feed or assist the animal.

How much does it cost to fly a pet on JetBlue?

JetBlue's Contract of Carriage (2026) says a fee applies to every in-cabin pet and that payment must be made when the reservation is made. The contract does not state the dollar amount, and JetBlue's public Optional Services and Fees page did not list a pet fee when reviewed in September 2026.

Independent sources agree on the current figure. Pet Travel Advisors, which says it checked JetBlue's published pages in September 2026, reports a fee of $150 each way, or $300 round trip. Older guides still list $125. The fee can be added in the Extras section during booking or later in Manage Trips, and several guides report that it can be paid with TrueBlue points before check-in. Treat the checkout price on jetblue.com as final.

How many pets can you bring on JetBlue?

This is where JetBlue's own documents disagree, so read both.

• Traveling with Pets help page (2026): a maximum of two pets per traveler, each in its own carrier. To bring a second pet you must buy a second seat and pay a second pet fee.
• Contract of Carriage (July 29, 2026): a passenger may not transport more than one pet per flight.

Both documents agree that no more than six pets may travel in the cabin on any single flight. Because the contract is the legally binding document, anyone planning to fly with two animals should get written confirmation from JetBlue before paying.

If you buy an extra seat, the carrier must go under the seat in front of you for taxi, takeoff and landing, then may be placed on the purchased seat during the flight. The pet never leaves the carrier.

Where can you sit with a pet?

JetBlue says customers traveling with pets cannot sit in an emergency exit row, a bulkhead seat, a Mint seat, or any seat restricted for under-seat stowage. It recommends a window or aisle seat. Unaccompanied minors cannot travel with a pet.

How to fly a pet on JetBlue: step by step

1. Measure the animal and carrier. Confirm the carrier is no taller than 8.5 inches and that the pet can turn around inside it.
2. Check the route. Pets are not accepted to or from the UK, EU, Barbados or Trinidad and Tobago. If a partner airline operates any leg, its pet rules may apply instead.
3. Book early and add the pet. Only six pets fit on each flight. Add the pet in Extras and pay the fee at booking, as the contract requires.
4. Collect documents. Check destination rules with the USDA APHIS pet travel tool and, for dogs entering the U.S., the CDC Dog Importation Navigator.
5. Check in and get the tag. Check in online up to 24 hours ahead, then visit the full-service counter for a JetPaws bag tag for the carrier.
6. Clear security. Carry the pet through the TSA screening equipment while the empty carrier is inspected. JetBlue says animals are never put through the X-ray machine.
7. Board. Stow the carrier under the seat for taxi, takeoff and landing.

JetBlue service animal policy

Service animals follow a separate set of rules. JetBlue's Contract of Carriage defines a service animal as a dog, regardless of breed or type, that is individually trained to do work or perform tasks for a qualified individual with a disability, including a psychiatric disability. That definition matches the U.S. Department of Transportation (DOT) final rule under the Air Carrier Access Act (ACAA), published in the Federal Register on December 10, 2020.

Under JetBlue's contract:

• Service animals fly at no charge, with a limit of two per qualified passenger.
• The dog must be harnessed, leashed or otherwise tethered, and must fit in the passenger's foot space without blocking the aisle. It may not occupy a seat.
• If you booked more than 48 hours before departure, you must submit the U.S. DOT Service Animal Air Transportation Form 48 hours in advance.
• Animals in training are not transported.
• JetBlue may refuse a service animal that is too large, aggressive, or behaves inappropriately for a public setting.

Does JetBlue allow emotional support animals?

Not as service animals. The DOT's December 2020 rule, effective January 11, 2021, allows airlines to treat emotional support animals as pets. On JetBlue, that means an emotional support animal must meet the pet rules above: small dog or cat only, in-cabin carrier, and pet fee. Psychiatric service dogs that are individually trained to perform tasks still qualify as service animals.

International flights and banned routes

JetBlue says it accepts pets on all domestic flights. Internationally, Section 34 of its Contract of Carriage sets hard limits:

• No pets to or from the United Kingdom and the European Union. Service animals are carried there only as required by applicable law.
• No live animals or pets to Barbados or Trinidad and Tobago, which JetBlue attributes to strict local government requirements.

For all other trips, the passenger is responsible for health and rabies vaccination certificates. JetBlue notes that Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets, and that vaccination rules differ from state to state within the U.S.

For dogs returning to or entering the United States, the U.S. Centers for Disease Control and Prevention (CDC) is the primary authority. The CDC says the requirements depend on where the dog was vaccinated and which countries it visited in the previous six months. The United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) says in its March 2026 pet travel guidance that U.S.-vaccinated dogs that have been in a high-risk rabies country in the past six months need a Certification of U.S.-Issued Rabies Vaccination form, submitted by a USDA-accredited veterinarian before the dog leaves the country.

Codeshare and interline flights

JetBlue's Contract of Carriage says that on an interline itinerary, the partner airline's rules may apply to in-cabin pets. Several independent guides go further and report that JetBlue does not accept pets on interline or codeshare bookings at all. Either way, book the JetBlue-operated segments directly with JetBlue when traveling with an animal, and confirm pet acceptance for every leg.

Where sources disagree

• Pets per traveler: two on JetBlue's help page, one in the Contract of Carriage.
• Fee amount: $150 in September 2026 third-party reviews; $125 in older guides; no dollar amount in JetBlue's contract or fees page.
• JetPaws branding: one September 2026 guide says the JetPaws name no longer appears on JetBlue's pet pages, but JetBlue's current help page still refers to a JetPaws bag tag. Claims about TrueBlue points earned per pet segment could not be confirmed on JetBlue's current pet page.

JetBlue pet rules vs. an Animal Passport record

Travelers sometimes search for an animal passport when they mean airline or government pet travel documents. These are different things. JetBlue relies on government health and rabies certificates, USDA APHIS endorsements and CDC import rules. No airline document or third-party app replaces them.

Animal Passport is a digital animal and livestock identity record, not a government-issued travel document, and it is not accepted by JetBlue in place of official paperwork. It identifies an animal by its muzzle print, which is unique like a fingerprint and captured with a phone. The record links the owner, breed, estimated age (from a dental photograph, with a confidence score), a 1 to 5 body condition score from a side-profile photo, and vaccination history. In August 2025 it was used in livestock flood rescue in Pakistan so farmers could reclaim animals after paper tags washed away.

For airline travel, follow JetBlue, USDA APHIS and CDC rules. For animal identity and ownership records, especially livestock, see the Animal Passport blog.

Bottom line

As of September 2026, JetBlue is one of the simplest U.S. airlines to plan around because it gives almost no options. If your dog or cat fits in an 8.5-inch-high carrier under the seat, and your route avoids the UK, EU, Barbados and Trinidad and Tobago, you can book it in the cabin for a fee reported at $150 each way. If your animal does not fit, JetBlue cannot carry it at any price. Airline rules change often, so check JetBlue's Traveling with Pets page and your booking checkout before you fly.
