JetBlue Pets Policy 2026: What You Need to Fly With a Dog or Cat

JetBlue pets policy, in short: JetBlue Airways (IATA code B6) lets small dogs and cats fly in the cabin only, in a leak-proof carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat in front of you. It has no cargo option and does not carry large dogs. As of October 2026, independent trackers report the pet fee at $150 each way, with a limit of six pets per flight. Pets are banned on flights to the UK, the EU, Barbados, and Trinidad and Tobago.

"JetBlue pets" refers to JetBlue's in-cabin pet program, branded JetPaws. It covers which animals can fly, how they must be contained, what it costs, and which destinations are excluded. This guide is written by the Animal Passport editorial team and was last updated on October 5, 2026. It uses JetBlue's own help page, JetBlue's Contract of Carriage dated April 17, 2026, the U.S. Centers for Disease Control and Prevention (CDC), and the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). Where those sources disagree, we say so.

What is JetBlue's pet policy?

JetBlue's Traveling with Pets help page (2026) says 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's Contract of Carriage (April 17, 2026) adds that "no animals are allowed to be transported on Carrier as checked baggage" and that no animals other than small dogs and cats are accepted as pets.

The other core rules on JetBlue's 2026 help page are:

• One pet per carrier. The pet must be able to stand up and turn around comfortably inside the closed carrier.
• The carrier is your personal item. The pet and carrier count as your one personal item and must fit under the seat in front of you.
• The carrier stays zipped. Your pet must stay inside the closed carrier at the airport and on board. You may unzip it briefly to feed or help your pet.
• No unaccompanied minors with pets. Children flying as unaccompanied minors cannot bring a pet.
• No Mint. Pets are not allowed in JetBlue's Mint premium cabin, according to both the help page and the Contract of Carriage.
• No pet remains. JetBlue does not accept pet remains, cremated or otherwise, in the cabin or as cargo.

Service animals are handled under separate rules. JetBlue's Contract of Carriage (2026) accepts up to two trained service animals per qualified traveler at no charge. It requires the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form 48 hours before departure when the trip was booked more than 48 hours ahead.

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

JetBlue's Contract of Carriage (April 2026) says only that "a fee will apply to transport a pet in-cabin and payment must be made at the time the Passenger makes their reservation." When we checked in October 2026, JetBlue's public Optional Services and Fees page and its pet help page did not list a dollar amount.

Independent trackers do publish a figure. Paws On Board (policy last updated April 20, 2026) and Jet Set Pets (May 12, 2026) both put the JetBlue pet fee at $150 each way, which works out to $300 for a round trip. Paws On Board also says the fee can be paid with TrueBlue points before check-in. Some guides still quote older, lower amounts, so confirm the price in the Extras step of your booking before you pay for the ticket.

Other costs to plan for:

• A second pet means a second seat. JetBlue's help page (2026) says that to bring a second pet, "a second seat and pet fee must be paid."
• An airport carrier costs $55. JetBlue sells approved carriers at the airport ticket counter for USD $55, while supplies last (JetBlue, 2026).
• Travel credits cannot be used. JetBlue's Adding Bags and Paying Fees page lists pet fees among the extras that JetBlue travel credits do not cover.

JetBlue pet carrier size and requirements

According to JetBlue's help page (2026), a JetBlue pet carrier must meet all of the following:

• No larger than 17 in L x 12.5 in W x 8.5 in H (43.18 cm x 31.75 cm x 21.59 cm).
• A leak-proof bottom and good ventilation.
• Soft-sided or hard-sided. Both are accepted.
• No gaps or openings a pet could escape through. Carriers that allow escape are refused.

JetBlue's general personal-item limit is 17 x 13 x 8 inches. The pet carrier limit is a separate figure, with a slightly narrower width but a taller height. A soft-sided carrier that compresses a little under the seat is usually easier to fit than a rigid one, but it still has to meet the published maximums.

Is there a weight limit for pets on JetBlue?

The sources disagree here. JetBlue's current help page (2026) gives no weight limit and uses carrier size as the test. JetBlue's 2008 JetPaws launch press release said that "the combined weight of the pet and carrier may not exceed 20 pounds." Several 2026 third-party guides, including Jet Set Pets, still quote that 20-pound figure. To be safe, keep pet and carrier at or under 20 pounds, and treat the under-seat fit as the rule that decides whether your pet can board.

How many pets can fly on a JetBlue flight?

JetBlue's Contract of Carriage (April 17, 2026) says a maximum of six pets may travel in-cabin on any flight. That cap is shared by everyone on board, so on busy routes the pet spots can sell out before the flight does.

The limit per traveler is less clear. JetBlue's help page (2026) allows up to two pets per traveler, each in its own carrier, with a second seat and a second fee. The same Contract of Carriage, however, still says "a Passenger may not transport more than one pet per flight." If you plan to bring two animals, ask JetBlue to confirm both reservations before you pay.

Where can't you fly with a pet on JetBlue?

JetBlue's help page (2026) says the airline "accepts pets on all domestic flights." International routes are more restricted. JetBlue's Contract of Carriage (April 2026, Section 34) says that:

• Pets are not permitted to or from the United Kingdom and the European Union. Service animals are accepted as required by law.
• Live animals and pets are not carried to Barbados or Trinidad and Tobago because of those governments' strict import requirements.

Jet Set Pets (May 2026) lists a longer set of JetBlue no-pet destinations. Besides the UK, Europe, and Trinidad and Tobago, it names Belize, Cartagena (Colombia), the Dominican Republic, Guayaquil (Ecuador), Guatemala, Guyana, Haiti, and San Pedro Sula (Honduras). JetBlue's Contract of Carriage does not list those countries. However, most of them appear on the CDC's list of high-risk countries for dog rabies, which makes bringing a dog back into the U.S. much harder. Check your exact route with JetBlue before booking.

Codeshare and interline trips are also different. JetBlue's Contract of Carriage (2026) says a partner airline's rules on in-cabin pets may apply to segments it operates, and Paws On Board (2026) reports that pets are not accepted on JetBlue interline or codeshare bookings.

What documents does a pet need to fly JetBlue?

JetBlue puts the paperwork on the traveler. Its help page (2026) says that "customers are responsible for understanding the animal import requirements and acquiring all necessary documentation before traveling with a pet." It points travelers to USDA APHIS, the CDC, and the International Air Transport Association (IATA) country database.

Domestic flights

Vaccination requirements for travel within the U.S. vary by state. JetBlue (2026) notes that Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets.

International flights and returning to the U.S.

The CDC is the main authority for dogs entering or returning to the United States, according to USDA APHIS (page last modified March 20, 2026). Under CDC rules in effect since August 1, 2024, a dog that has been only in rabies-free or low-risk countries for the past 6 months needs:

1. A free CDC Dog Import Form receipt, one per dog, valid for 6 months.
2. A microchip that a universal scanner can read.
3. A minimum age of 6 months at the time of entry.
4. A healthy appearance on arrival.

A dog that has been in any CDC high-risk country in the past 6 months must also meet the CDC's high-risk requirements. For U.S.-vaccinated dogs, USDA APHIS (2026) says that includes a Certification of U.S.-Issued Rabies Vaccination form submitted by a USDA-accredited veterinarian before the dog leaves the U.S. Cats are not covered by the CDC dog rules, but destination countries may set their own requirements. For any trip out of the U.S., USDA APHIS advises contacting a USDA-accredited veterinarian as soon as you decide to travel.

How to fly with a pet on JetBlue, step by step

1. Check that your route allows pets. Use the Contract of Carriage rules above and confirm with JetBlue for any international route.
2. Book early and add the pet in Extras. The six-per-flight cap means pet spots go first. The Contract of Carriage says the fee is paid when you make the reservation.
3. Choose an allowed seat. JetBlue (2026) does not let pet travelers sit in emergency exit rows, bulkhead seats, Mint seats, or any seat restricted for under-seat stowage. It recommends a window or aisle seat.
4. Get your carrier ready. Measure it against 17 x 12.5 x 8.5 inches and let your pet spend time in it before the trip.
5. Gather the paperwork. This means state or territory vaccination records for domestic trips, and CDC and destination documents for international ones.
6. Check in and collect the JetPaws tag. You can check in online up to 24 hours ahead. At the airport, go to the full-service counter or find a JetBlue crewmember to get the JetPaws bag tag for the carrier (JetBlue, 2026).
7. Go through TSA screening. You will hold your pet and walk through the screening equipment while the empty carrier is inspected. JetBlue says your animal "will never be placed through an x-ray machine."
8. Stow the carrier for taxi, takeoff, and landing. The carrier must be under the seat in front of you during those phases. During the flight you may hold it on your lap, or place it on an extra seat you bought, but the pet must stay inside.

JetBlue pet rules at a glance

JetBlue pet documents vs. Animal Passport: not the same thing

The word "passport" causes confusion, so here is the difference. The documents JetBlue relies on are government and airline records: the CDC Dog Import Form, rabies certificates, USDA-endorsed health certificates, and destination import permits. Animal Passport is none of these. It is not a government-issued travel document, not an EU pet passport, and not something JetBlue asks for.

Animal Passport is a digital animal and livestock identity record built on muzzle biometrics. An animal's nose print is unique, much like a human fingerprint. A farmer or owner captures it with a phone, and the record links the animal to its owner, breed, estimated age (from a dental photo, with a confidence score), body condition score (1 to 5, from a side-profile photo), and vaccination history. In Pakistan's August 2025 floods, Animal Passport was used in livestock rescue so farmers could reclaim animals after paper ear tags washed away.

This matters for JetBlue travelers in one practical way. USDA APHIS (2026) says that animals "considered livestock or poultry, like pigs or chickens" do not qualify for pet travel, and JetBlue carries only cats and dogs anyway. Goats, lambs, and calves are a separate regulatory world, and that world is where Animal Passport's identity tools apply. More coverage is on the Animal Passport blog.

Bottom line

JetBlue is a workable choice for owners of small dogs and cats on domestic routes and many Caribbean and Latin American routes. Book early, measure your carrier, and confirm the fee at checkout. It is not an option for large dogs, for any animal that needs cargo transport, or for trips to the UK, the EU, Barbados, or Trinidad and Tobago. Because JetBlue's help page and its Contract of Carriage disagree on some points, get written confirmation from JetBlue on anything that would decide whether your pet can fly.
