JetBlue Flying With a Dog: The 2026 In-Cabin Pet Policy Explained

Can you fly JetBlue with a dog? Yes, if the dog is small. JetBlue carries small dogs and cats in the cabin only, 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 does not accept large dogs, and it never carries pets in the hold. A maximum of six pets may fly on each flight. You pay a pet fee each way, and independent trackers reported that fee as $150 in 2026.

JetBlue flying with a dog means booking your dog into JetBlue Airways' in-cabin pet program, called JetPaws. Under JetPaws, the dog rides in a closed carrier at your feet and is not checked as baggage. This guide was last updated in October 2026 by the Animal Passport editorial team. It checks every rule against JetBlue's own help page and its Contract of Carriage, plus guidance from 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).

JetBlue pet policy at a glance (as of October 2026)

• Which animals: Small dogs and cats only. JetBlue's Traveling with Pets page (2026) says no large dogs are accommodated.
• Where the dog rides: Only in the cabin. JetBlue's Contract of Carriage (version dated July 29, 2026) says no animals are transported as checked baggage.
• Carrier size: No larger than 17 in L x 12.5 in W x 8.5 in H (43.18 x 31.75 x 21.59 cm), according to JetBlue's help page (2026).
• Pets per flight: A maximum of six in the cabin, according to the JetBlue Contract of Carriage (2026).
• Pets per traveler: Up to two according to JetBlue's help page, but the contract says one. The section on source disagreements below explains this.
• Cabins and passengers excluded: Pets are not allowed in Mint, JetBlue's premium cabin, and unaccompanied minors cannot travel with a pet (Contract of Carriage, 2026).
• Pet remains: JetBlue does not accept pet remains, cremated or otherwise, in the cabin or as cargo.

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

Plan on about $150 each way, but confirm the price when you book. As of October 2026, JetBlue's Traveling with Pets page and its Optional Services and Fees page do not print a dollar figure. The July 2026 Contract of Carriage says only that a fee will apply and must be paid when you make the reservation.

Here is what other sources say. JetBlue's September 2024 Contract of Carriage set the fee at $125 per pet, each way. Two independent pet-travel trackers, Paws On Board (policy updated April 20, 2026) and Jet Set Pets (May 2026), now report $150 each way. Paws On Board also reports that the fee can be paid with TrueBlue points before check-in.

Some related costs are confirmed on JetBlue's own pages:

• Airport carrier: JetBlue sells FAA-approved carriers at the airport ticket counter for USD $55 while stock lasts (JetBlue help page, 2026).
• Second pet: A second pet needs its own seat and a second pet fee (JetBlue help page, 2026).
• Refunds: Pet fees are refunded to the original payment method if you cancel the booking before departure (JetBlue Fare Options page, 2026).

JetBlue pet carrier rules and size limits

The carrier is where most trips succeed or fail at the gate. JetBlue's 2026 rules require:

• Maximum dimensions of 17 in L x 12.5 in W x 8.5 in H (43.18 x 31.75 x 21.59 cm).
• A leak-proof bottom and good ventilation. Both soft-sided and hard-sided carriers are accepted.
• One pet per carrier. The dog must be able to stand up and turn around comfortably with the carrier closed.
• No containers that could let the pet escape.

The carrier and dog count as your personal item. JetBlue's Fare Options page (2026) says travelers who add a pet can still bring a full-size carry-on bag, including on Main Base fares. Pet strollers count as carry-on items unless a service dog uses the stroller, in which case it counts as an assistive device.

Is there a weight limit for dogs on JetBlue?

JetBlue does not publish a weight limit. The test is whether your dog fits comfortably in a compliant carrier under the seat. Sources disagree on this point. Jet Set Pets (2026) states a 20-pound combined limit for pet and carrier, while Paws On Board (2026) says JetBlue specifies no maximum weight. In practice, a dog that cannot stand and turn around inside a 17 x 12.5 x 8.5 inch carrier will not qualify, whatever it weighs.

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

1. Check that your dog qualifies. It must be a small dog that fits the carrier rules. Large dogs cannot fly on JetBlue unless they are trained service dogs.
2. Check your route. Make sure your destination is not on JetBlue's no-pet list. The international section below covers this.
3. Add the pet early. Because only six pets can fly on each flight, add your dog when you book. Paws On Board (2026) reports that you can add the pet in the Extras step during booking, or later in Manage Trips on jetblue.com or My Trips in the JetBlue app.
4. Gather documents. Vaccination rules vary by U.S. state. Puerto Rico and the U.S. Virgin Islands require vaccination documentation, according to JetBlue (2026). For other destinations, JetBlue points travelers to the USDA APHIS pet travel tool, the CDC, and the International Air Transport Association (IATA) country database.
5. Check in. Once the fee is paid and the pet is confirmed, you can check in 24 hours before departure online, in the app, or at a kiosk.
6. Get the JetPaws bag tag. At the airport, go to the full-service counter or ask a JetBlue crewmember for a JetPaws bag tag to attach to the carrier.
7. Clear security. At the Transportation Security Administration (TSA) checkpoint, you carry your dog through the screening equipment while the carrier is inspected. JetBlue states that the animal is never put through an x-ray machine.
8. Board and stow. The carrier goes under the seat in front of you for taxi, takeoff, and landing. During the flight, you may hold the closed carrier on your lap.

Where can you sit with a dog on JetBlue?

JetBlue's 2026 help page says travelers with pets cannot sit in emergency exit rows, bulkhead seats, Mint seats, or any seat restricted for under-seat stowage. JetBlue recommends a window or aisle seat. Your dog must stay in its zipped carrier the whole time you are at the airport and on board. You may unzip it briefly to feed or assist the dog.

If you bought an extra seat for a second pet, the carrier must be under a seat for taxi, takeoff, and landing. It can sit on the empty seat during the flight. Pet relief areas vary by airport, and JetBlue warns that you may need to leave and re-clear security if your dog needs to relieve itself.

Pet dog vs. service dog on JetBlue: comparison

JetBlue's contract defines a service animal as a dog that is individually trained to work for a person with a disability, and it does not transport animals in training. Paws On Board (2026) notes that JetBlue has not accepted emotional support animals since the U.S. Department of Transportation rule change that took effect in January 2021. Emotional support dogs therefore travel as pets under the JetPaws rules.

Flying internationally with a dog on JetBlue

International trips add a second set of rules on top of JetBlue's. The airline's July 2026 Contract of Carriage states:

• Barbados and Trinidad and Tobago: Pets are not transported, because of strict local government requirements.
• United Kingdom and European Union: Pets are not permitted on these routes. Service animals are permitted as required by applicable law.
• Codeshare and interline partners: Different pet rules apply. Paws On Board (2026) reports that pets are not accepted on interline or codeshare bookings.

Jet Set Pets (2026) lists more destinations where it says JetBlue is not currently accepting pets, including airports in the Dominican Republic, Haiti, Guyana, Ecuador, Colombia (Cartagena), Guatemala, Honduras, and Belize. That list does not appear in the Contract of Carriage text we reviewed. Treat it as a reason to confirm your exact route with JetBlue before you buy.

Bringing your dog back into the United States

The CDC is the primary authority for dogs entering or returning to the U.S., according to USDA APHIS (2026). Since August 1, 2024, the CDC has required the following for dogs that have been only in dog-rabies-free or low-risk countries during the previous 6 months:

• A CDC Dog Import Form receipt. The form is free, and the receipt is valid for 6 months.
• The dog must be at least 6 months old.
• The dog must have a microchip that a universal scanner can detect.
• The dog must appear healthy on arrival.

Dogs that have been in a high-risk country face stricter rules. USDA APHIS (2026) says U.S.-vaccinated dogs that visited a high-risk country within 6 months need a Certification of U.S.-Issued Rabies Vaccination, submitted by a USDA-accredited veterinarian before the dog leaves the U.S. If you are flying out of the U.S., APHIS advises contacting a USDA-accredited veterinarian as soon as you decide to travel.

Where JetBlue's own sources disagree

Some of JetBlue's own documents contradict each other, so check before you rely on any single page.

• Pets per traveler: JetBlue's Traveling with Pets page allows up to two pets per traveler if you buy a second seat and pay a second fee. The July 2026 Contract of Carriage says a passenger may not transport more than one pet per flight. If you plan to bring two dogs, get written confirmation from JetBlue when you book.
• Fee: The 2024 contract listed $125 each way. Third-party trackers reported $150 in 2026. Current JetBlue pages do not state an amount.
• Weight: JetBlue publishes no weight cap, but some guides cite 20 pounds.

Is Animal Passport a pet travel document for JetBlue?

No. JetBlue requires its own pet booking plus whatever destination paperwork government agencies such as the CDC and USDA APHIS require. Animal Passport is a different kind of product. It is a digital animal and livestock passport that identifies an animal by its muzzle print, which is unique like a fingerprint. The record is captured on a phone and links the animal to its owner, breed, estimated age, body condition, and vaccination history. Age is estimated from a dental photograph and comes with a confidence score. Body condition is scored from 1 to 5 using a side-profile photo.

The system was used during livestock flood rescue in Pakistan in August 2025, so farmers could reclaim animals after paper ear tags washed away. That is ownership and identity proof for livestock. It is not a government-issued travel document, and it does not replace a JetPaws booking, a CDC Dog Import Form, a microchip, or a veterinary health certificate. For more on animal identification and travel rules, browse the Animal Passport blog.

Practical tips for a calmer JetBlue flight with your dog

• Measure your carrier at home against 17 x 12.5 x 8.5 inches. If it is borderline, JetBlue sells compliant carriers at the counter for $55 while stock lasts.
• Get your dog used to the carrier weeks before the flight, a step Jet Set Pets (2026) recommends.
• Arrive early enough to collect the JetPaws tag at the full-service counter before security.
• Choose a window seat if you can. It keeps the carrier out of the aisle, and JetBlue recommends window or aisle seats.
• Keep vaccination records on your phone and on paper, especially for Puerto Rico, the U.S. Virgin Islands, and any international trip.
