JetBlue Dog Travel in 2026: Fees, Carrier Size, Documents and Rules

JetBlue dog travel means flying with a small dog in the cabin of a JetBlue Airways flight. JetBlue calls this its JetPaws program, and it's the only option because the airline doesn't carry dogs as checked baggage or cargo. As of October 2026, JetBlue requires a carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat in front of you. It caps each flight at six in-cabin pets and doesn't accommodate large dogs.

Third-party policy trackers report a pet fee of $150 each way in 2026. JetBlue's official pages don't print that number, so confirm the price when you book. The rest of this guide covers booking, carrier size, documents, international limits and service dogs. It also notes the places where JetBlue's own documents disagree.

JetBlue dog travel at a glance (October 2026)

Does JetBlue allow dogs on planes?

Yes, but only small ones. JetBlue's Traveling with Pets 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." It also says plainly that "no large dogs are accommodated on JetBlue." JetBlue's Contract of Carriage (version dated April 17, 2026) adds that "no animals are allowed to be transported on Carrier as checked baggage." Small dogs and cats are the only animals it accepts in the cabin.

So JetBlue has no cargo option for a Labrador or a German Shepherd. If your dog can't fit in an under-seat carrier, you'll need a different airline or a professional pet shipper. The only exception is a trained service dog, covered below.

Is there a weight limit for dogs on JetBlue?

JetBlue's official pages don't state a weight limit. The rule is about fit: the dog has to stand up and turn around inside a closed carrier that fits under the seat. Paws On Board (2026) says JetBlue doesn't specify a maximum weight. Jet Set Pets (May 2026) says the dog and carrier together can't exceed 20 pounds. Because the sources disagree, use the carrier dimensions as your real test, and treat 20 pounds as an informal rule of thumb rather than JetBlue policy.

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

Paws On Board (policy updated April 20, 2026) and Jet Set Pets (May 2026) both report a JetBlue pet fee of $150 each way, payable in cash or TrueBlue points. JetBlue's Contract of Carriage (2026) confirms that "a fee will apply to transport a pet in-cabin" and that payment is due when you make the reservation, but it doesn't give the amount. JetBlue's Optional Services and Fees page lists bag, seat and change fees but no pet fee, as viewed in October 2026. The safest approach is to add your pet during booking and check the price on the payment screen.

A second pet costs more than a second fee. JetBlue's help page (2026) says a second pet needs its own carrier, a second seat and a second pet fee. If you forget a carrier, JetBlue sells approved ones at the airport ticket counter for $55 while supplies last.

JetBlue pet carrier rules

JetBlue's Traveling with Pets page (2026) sets these carrier requirements:

• The carrier can't be larger than 17" L x 12.5" W x 8.5" H (43.18 x 31.75 x 21.59 cm).
• It needs a leak-proof bottom and good ventilation.
• Soft-sided and hard-sided carriers are both accepted.
• JetBlue won't accept carriers that could let the animal escape.
• Only one pet per carrier, and the pet must be able to stand up and turn around comfortably with the carrier closed.
• Your pet and its carrier count as your personal item and must fit under the seat in front of you.

In practice, 8.5 inches of height is the limit most owners run into. A soft-sided carrier that compresses a little under the seat is usually easier to fit than a rigid crate of the same size.

How to book and fly with your dog on JetBlue: step by step

1. Check that your dog qualifies. It must be a small dog that can turn around in a carrier no larger than 17 x 12.5 x 8.5 inches. Make sure the route isn't on JetBlue's restricted list (see the international section below).
2. Book early and add the pet when you book. JetBlue's Contract of Carriage (2026) caps each flight at six in-cabin pets and says the pet fee is due at reservation. Don't book a JetBlue codeshare or interline itinerary without checking first, because the contract applies different pet rules to partner flights.
3. Choose an eligible seat. JetBlue's help page (2026) bars travelers with pets from emergency exit rows, bulkhead seats, Mint seats and any seat with restricted under-seat storage. JetBlue recommends a window or aisle seat.
4. Gather your documents. Requirements for domestic trips vary by state. JetBlue says Puerto Rico and the U.S. Virgin Islands require vaccination documentation. For international trips, use the USDA APHIS pet travel tool and the CDC pages linked below.
5. Check in. Once the fee is paid and your pet is confirmed, you can check in 24 hours before departure online, in the JetBlue app or at a kiosk. Then go to the full-service counter or find a JetBlue crewmember to get the JetPaws bag tag for the carrier.
6. Go through security. According to JetBlue's guidance on Transportation Security Administration (TSA) screening, you'll carry your dog through the screening equipment while the carrier is inspected. JetBlue says your animal will never go through an X-ray machine.
7. Fly. The carrier stays under the seat in front of you during taxi, takeoff and landing. During the flight you can hold the carrier on your lap, or put it on the extra seat if you bought one. Either way, the dog stays zipped inside the carrier.

Can you take a dog on JetBlue internationally?

Sometimes. JetBlue's Contract of Carriage (April 2026) says the airline doesn't carry live animals or pets to Barbados or to Trinidad and Tobago because of those governments' requirements. It also says that "for travel to and from the United Kingdom and the European Union, pets will not be permitted," although service animals are accepted where the law requires. That rules out JetBlue's transatlantic routes for pet dogs.

Jet Set Pets (May 2026) lists more destinations where it says JetBlue isn't accepting pets, including Belize, Colombia (Cartagena), the Dominican Republic, Ecuador, Guatemala, Guyana, Haiti and Honduras. JetBlue's Contract of Carriage doesn't name those countries, so check the route with JetBlue before you book.

The entry rules for your destination are a separate question. JetBlue's help page tells customers to use the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) pet travel tool, the CDC website and the International Air Transport Association (IATA) database. JetBlue also notes that the APHIS tool's destination requirements "do not override JetBlue's policies." USDA APHIS (page last modified March 20, 2026) advises contacting a USDA-accredited veterinarian as soon as you decide to travel abroad, because health certificates and tests take time.

Bringing your dog back into the United States

The CDC is the main authority for dogs entering the U.S. Since August 1, 2024, CDC rules have required every dog entering or returning to the U.S. to arrive with a CDC Dog Import Form receipt, look healthy, be at least 6 months old, and have a microchip that a universal scanner can read. For a dog that has only been in rabies-free or low-risk countries in the past six months, the receipt is the only document required. The form is free, and the receipt is valid for six months for repeat entries from the same departure country (CDC, 2024). Dogs that have been in a high-risk country for dog rabies need more paperwork. USDA APHIS notes that U.S.-vaccinated dogs in that situation need a Certification of U.S.-Issued Rabies Vaccination completed by a USDA-accredited veterinarian before the dog leaves the U.S.

JetBlue service dogs vs. pets vs. emotional support animals

The U.S. Department of Transportation (DOT) changed the federal rules for animals on planes in a final rule published in the Federal Register on December 10, 2020, effective January 11, 2021. It defines a service animal as "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." It also lets airlines treat emotional support animals as pets.

JetBlue's Contract of Carriage (2026) applies that rule as follows:

• Service animals fly free, with a limit of two per qualified passenger. They must be harnessed, leashed or otherwise tethered.
• If you booked more than 48 hours before departure, JetBlue requires the U.S. Department of Transportation Service Animal Air Transportation Form at least 48 hours in advance.
• A service animal must fit in the passenger's foot space without blocking an aisle, and it can't occupy a seat.
• JetBlue doesn't transport animals that are still in training.

An emotional support dog therefore flies on JetBlue under the normal pet rules: it needs to be small, in a carrier, and paid for. A large emotional support dog can't fly on JetBlue at all.

Where JetBlue's own documents disagree

We found two inconsistencies while researching this guide. You should know about them before you book.

• Pets per traveler. JetBlue's Traveling with Pets page allows "a maximum of two pets per traveler," with the second needing its own seat and fee. The Contract of Carriage dated April 17, 2026 says "a Passenger may not transport more than one pet per flight." If you plan to bring two dogs, get written confirmation from JetBlue first.
• Fee transparency. Third-party trackers consistently report $150 each way, but JetBlue's official pet and fees pages that we viewed don't state the amount.

Is a pet passport or Animal Passport record accepted by JetBlue?

Animal Passport is a different kind of product. JetBlue's Contract of Carriage says passengers must comply with destination laws, "including furnishing valid health and rabies vaccination certificates when required." For U.S. entry, the CDC relies on a microchip and the CDC Dog Import Form. Government-endorsed certificates come from USDA-accredited veterinarians and official authorities, not from private apps.

Animal Passport is a digital animal and livestock passport based on muzzle biometrics: the nose print of an animal is unique, like a fingerprint. You capture it with a phone. The record links the owner, breed, estimated age (from a dental photograph, with a confidence score), body condition score (1 to 5, from a side-profile photo) and vaccination history. It was used during livestock flood rescue in Pakistan in August 2025, so farmers could reclaim animals after their paper ear tags washed away.

That makes it a proof-of-identity and ownership tool. It isn't a government-issued travel document. It isn't the EU pet passport. It isn't a CDC form or a USDA health certificate, and JetBlue doesn't list it as an accepted document. For a JetBlue trip, use your microchip, CDC receipt and veterinary certificates. A biometric record can help you keep your own files organized, but it doesn't replace any of them. You can read more about animal identification on the Animal Passport blog.

Practical tips for a smoother JetBlue flight with a dog

• Measure first. Check the carrier's height against the 8.5-inch limit before you buy, and practice zipping your dog in at home for longer periods each day.
• Plan relief breaks. JetBlue warns that the location of pet relief areas varies by airport, and you may have to leave the airport and go back through security if your dog needs to relieve itself.
• Keep the carrier closed. JetBlue says you may unzip the carrier only to feed or help your pet. It stays zipped the rest of the time, both in the terminal and on board.
• Bring digital and paper copies of vaccination records and any CDC receipt. The CDC says a receipt can be printed or shown on a phone.
• Re-check the rules within a week of departure. JetBlue updated its Contract of Carriage in April 2026, and pet rules change from year to year.

The bottom line on JetBlue dog travel

JetBlue works well if your dog is small enough to ride under the seat in a 17 x 12.5 x 8.5 inch carrier. It doesn't work for large dogs or for any trip to the UK or EU. Book early because of the six-pet limit, confirm the fee and the number of pets allowed directly with JetBlue, and if you're returning from abroad, file the CDC Dog Import Form before you head to the airport.
