Flying With Pets on JetBlue in 2026: Rules, Fees, Carrier Size and Paperwork

Flying with pets on JetBlue means travelling with a small dog or cat in the cabin under JetBlue's JetPaws program, because JetBlue Airways does not carry any animal in cargo or as checked baggage. As of October 2026, JetBlue allows up to six in-cabin pets per flight, requires a ventilated, leak-proof carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat, and charges a per-direction pet fee (widely reported as $150). Pets cannot sit in Mint.

By Animal Passport. Last updated: October 5, 2026. This guide is built from JetBlue's own help page, JetBlue's Contract of Carriage dated April 17, 2026, and United States government sources. Airline rules change often, so check the official pages linked below before you book.

What is JetBlue's pet policy in 2026?

JetBlue's pet policy is a cabin-only policy for small dogs and cats. JetBlue's help page states that "only small dogs and cats may travel in the cabin in an FAA-approved pet carrier that fits comfortably under the seat in front of you" and that "no large dogs are accommodated on JetBlue" (JetBlue, 2026). The Federal Aviation Administration (FAA) reference here is about the carrier fitting under-seat stowage rules, not a separate FAA certificate you need to obtain.

JetBlue's Contract of Carriage (April 17, 2026) adds the legal baseline: no animals as checked baggage, no animals other than small dogs and cats, no pets in Mint, no pets with unaccompanied minors, one pet per kennel, and a maximum of six pets in the cabin on any flight.

JetBlue also states that it does not accept pet remains, cremated or otherwise, in the cabin or as cargo (JetBlue, 2026).

JetBlue pet rules at a glance

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

JetBlue charges a pet fee each way for every in-cabin pet. Third-party policy trackers, including Paws On Board (policy last updated April 20, 2026), list the JetBlue pet fee as $150 USD each way and say it can be paid with TrueBlue points before check-in.

We could not find that dollar figure on the JetBlue pages we reviewed. JetBlue's "Traveling with Pets" help page refers to "the pet fee" without a price, and JetBlue's Optional Services and Fees page (October 2026) lists bags, seats and onboard items but no pet line. Treat $150 as the reported figure and confirm the exact amount in the Extras step of your booking.

Two other costs are documented by JetBlue itself:

• Airport pet carrier: JetBlue sells carriers at the airport ticket counter for USD $55, in limited quantities (JetBlue, 2026). The help page also says carriers can be bought online or at the John F. Kennedy International Airport (JFK) Terminal 5 counter.
• Extra seat: To bring a second pet, JetBlue's help page says you must pay for a second seat plus a second pet fee.

When do you have to pay?

JetBlue's Contract of Carriage (April 2026) says payment for an in-cabin pet "must be made at the time the Passenger makes their reservation." Paws On Board reports that the fee can also be added later in Manage Trips. Because the contract is the binding document, the safest approach is to add the pet when you buy the ticket.

JetBlue pet carrier size and weight limits

JetBlue's maximum pet carrier size is 17 inches long, 12.5 inches wide and 8.5 inches high (43.18 x 31.75 x 21.59 cm), according to JetBlue's help page (2026). The pet must be able to stand up, turn around and move comfortably inside the closed carrier.

• Soft-sided and hard-sided carriers are both accepted.
• The bottom must be leak-proof and the carrier well ventilated.
• Carriers that could allow escape are refused.
• The pet and carrier count as your one personal item.

JetBlue does not publish a maximum pet weight on its help page. Some third-party sites cite a 20-pound combined limit for pet plus carrier, but that figure does not appear on the JetBlue page we reviewed. In practice, size is the limit: if your pet cannot turn around in a carrier that fits the dimensions above, it cannot fly on JetBlue.

How many pets can you bring on JetBlue?

JetBlue allows a maximum of six pets in the cabin on any single flight, per its Contract of Carriage (April 2026). Once six pets are booked, no more can be added, which is why booking early matters on busy routes.

On pets per person, JetBlue's own documents disagree. The help page (2026) says "a maximum of two pets per traveler is allowed, each in their own carrier," with a second seat and second fee. The Contract of Carriage (April 17, 2026) says "a Passenger may not transport more than one pet per flight." If you plan to fly with two pets, call JetBlue and get the booking confirmed in writing before you travel.

How to book and fly with a pet on JetBlue: step by step

1. Check route eligibility. Confirm your destination is not the United Kingdom, European Union, Barbados or Trinidad and Tobago, where JetBlue does not carry pets (Contract of Carriage, 2026). Also check that the itinerary is JetBlue-operated, because codeshare and interline partners may apply their own in-cabin pet rules (Contract of Carriage, Sections 35 and 36).
2. Measure your carrier. It must not exceed 17 x 12.5 x 8.5 inches, and your pet must turn around inside it.
3. Add the pet when booking. Add the pet in the Extras step and pay the fee at reservation, as the Contract of Carriage requires.
4. Choose an allowed seat. Avoid Mint, exit rows, bulkhead rows and seats without under-seat stowage. JetBlue recommends a window or aisle seat.
5. Gather documents. Collect any vaccination records, health certificates and import forms your destination requires (see the documents section below).
6. Check in. Once the fee is paid and the pet is confirmed, check in from 24 hours before departure online, in the JetBlue app or at a kiosk (JetBlue, 2026).
7. Collect your JetPaws bag tag. Visit the full-service counter or a JetBlue crewmember in the self-service lobby for the JetPaws tag to attach to the carrier.
8. Clear Transportation Security Administration (TSA) screening. You hold your pet and walk through screening while the empty carrier is inspected; JetBlue notes the animal is never put through an X-ray machine.
9. Keep the pet in the carrier. The carrier stays zipped at the airport and on board, and must be under the seat for taxi, take-off and landing.

Where can your pet sit on a JetBlue flight?

JetBlue's help page (2026) says customers with pets cannot sit in an emergency exit row, a bulkhead seat, a Mint seat or any seat restricted for under-seat stowage. During the flight you may hold the closed carrier on your lap. If you bought an extra seat for the pet, the carrier can sit on that seat in flight but must go under the seat for taxi, take-off and landing. The pet must stay inside the carrier at all times, although JetBlue allows briefly unzipping it to feed or assist the animal.

Pet relief areas vary by airport, and JetBlue warns you may need to exit and re-clear security if your pet needs to relieve itself (JetBlue, 2026).

What documents do you need to fly a pet on JetBlue?

JetBlue makes the owner responsible for all animal paperwork. Its Contract of Carriage (2026) requires passengers to comply with destination laws, "including furnishing valid health and rabies vaccination certificates when required."

Domestic flights within the United States

JetBlue accepts pets on all domestic flights and notes that vaccination requirements vary from state to state (JetBlue, 2026). Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets.

Leaving the United States

The United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) advises owners taking a pet abroad to contact a USDA-accredited veterinarian as soon as they decide to travel, to identify destination requirements and obtain a USDA-endorsed pet health certificate where needed (USDA APHIS Pet Travel page, last modified March 20, 2026). JetBlue points travellers to the USDA APHIS pet travel tool but notes it does not override JetBlue's own policies.

Bringing a dog into or back to the United States

The U.S. Centers for Disease Control and Prevention (CDC) is the primary authority for dog imports, according to USDA APHIS (2026). Since August 1, 2024, dogs that have been only in dog rabies-free or low-risk countries for the previous six months need one document: the free CDC Dog Import Form receipt (CDC, 2024). The CDC also requires that these dogs appear healthy, are at least 6 months old and carry a microchip detectable by a universal scanner. Dogs that have been in a high-risk country face extra requirements, and USDA APHIS notes U.S.-vaccinated dogs in that situation need a "Certification of U.S.-Issued Rabies Vaccination" form completed by a USDA-accredited veterinarian before departure.

For other countries, JetBlue recommends the International Air Transport Association (IATA) Travel Centre database, under the Pets section of each country's information.

Service animals are different from pets on JetBlue

Service animals follow separate rules and are not charged a pet fee. JetBlue's Contract of Carriage (April 2026) defines a service animal as a dog individually trained for a person with a disability, accepts up to two per qualified traveller at no charge, and requires the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form 48 hours in advance when the booking was made more than 48 hours before departure. Service animals must fit in the passenger's foot space and may not occupy a seat. Animals in training are not transported.

Is Animal Passport a pet travel document for JetBlue?

No. Animal Passport is a digital animal and livestock passport that identifies an animal by its muzzle biometrics, since a nose print is unique like a fingerprint. Using a phone, the record binds 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.

It is not a government-issued travel document, it is not an EU pet passport, and JetBlue does not list it among accepted pet travel documents. For a JetBlue flight, you still need whatever JetBlue, the CDC, USDA APHIS and your destination require. Note also that USDA APHIS says animals considered livestock or poultry, such as pigs or chickens, do not qualify for pet travel at all and fall under separate import and export rules, which is a different world from JetBlue's small-dog-and-cat cabin policy.

Where Animal Passport does help is identity: in the August 2025 livestock flood rescue in Pakistan, farmers used biometric records to reclaim animals after paper tags washed away. Read more animal identity and travel explainers on the Animal Passport blog.

Practical tips before flying with pets on JetBlue

• Book early: the six-pet cap per flight fills on holiday and leisure routes.
• Do a carrier trial: have your pet spend time zipped in the carrier at home so it can rest calmly under a seat.
• Carry paper and digital copies of vaccination records and the CDC Dog Import Form receipt, which CDC says can be shown on a phone.
• Check the itinerary operator: codeshare or interline segments can change pet acceptance.
• Ask your veterinarian about fitness to fly and any destination tests; this article is not veterinary or legal advice.

As of October 2026, the rules above reflect JetBlue's published help page and its April 17, 2026 Contract of Carriage. When the two disagree, contact JetBlue before travel and keep the confirmation.
