JetBlue Flying With Dog: 2026 Rules, Fees, Carrier Size and Paperwork

Can you fly JetBlue with a dog? Yes. As of October 2026, JetBlue Airways accepts small dogs (and cats) in the cabin only, inside a leak-proof, ventilated carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat in front of you. JetBlue does not carry pets as checked baggage or cargo, caps each flight at six pets, charges a per-direction pet fee, and does not accept pets on flights to or from the United Kingdom or European Union.

JetBlue flying with dog means booking your dog as an in-cabin pet under JetBlue's JetPaws program: the dog rides in an approved carrier stowed under the seat, the carrier counts as your personal item, and you are responsible for any health paperwork your destination requires. This guide is published by Animal Passport and was last updated October 1, 2026, using JetBlue's own policy pages and its Contract of Carriage dated July 29, 2026.

JetBlue dog policy at a glance (October 2026)

The table below summarizes JetBlue's published rules. Each line is drawn from JetBlue's Traveling with Pets help page or its Contract of Carriage, both reviewed on October 1, 2026.

How big can my dog be to fly on JetBlue?

JetBlue does not publish a weight limit for dogs. Instead, the limit is set by the carrier: JetBlue's Traveling with Pets page (2026) says carriers cannot exceed 17 inches long, 12.5 inches wide and 8.5 inches high, and your dog must be able to stand up, turn around and move comfortably while the carrier is closed. In practice, that means toy and small breeds. JetBlue states plainly that "no large dogs are accommodated on JetBlue," with exceptions only for trained service animals.

One detail worth noticing: JetBlue's Flights Terms list the general personal-item limit as 17 x 13 x 8 inches, while the pet-carrier limit is 17 x 12.5 x 8.5 inches. For a dog, follow the pet-carrier figure, and measure a soft-sided bag when it is packed, not flat.

Can I buy a carrier at the airport?

Yes, with limits. According to JetBlue (2026), approved pet carriers can be bought online or at the JetBlue ticket counter at John F. Kennedy International Airport (JFK) Terminal 5 for USD $55, pending availability and with credit card payment only. Do not rely on this as your plan; quantities are limited.

How much does JetBlue charge to fly with a dog?

This is where official sources have become less specific. JetBlue's current Contract of Carriage (July 29, 2026) says only that "a fee will apply to transport a pet in-cabin," without naming an amount. JetBlue's Optional Services and Fees page, reviewed October 1, 2026, lists bag, seat and change fees but no pet fee.

• JetBlue's September 2024 Contract of Carriage set the charge at $125 per pet, each way.
• Paws On Board, an independent pet-travel database, lists the JetBlue fee as $150 each way in a policy summary last updated April 20, 2026.
• A second pet requires a second seat and a second pet fee, per JetBlue's help page (2026).

Because the amount is no longer printed in JetBlue's legal documents, treat the price shown in the JetBlue booking flow as the authoritative figure for your trip. On March 31, 2026, JetBlue announced that TrueBlue members can redeem points for select travel extras, including pet travel fees. JetBlue's fare FAQ also confirms that you can add a pet to a Main Base fare, space permitting, and that pet fees are refundable to the original form of payment if the booking is canceled before departure.

Can I bring two dogs on JetBlue?

JetBlue's own documents disagree here. The Traveling with Pets help page (2026) says "a maximum of two pets per traveler is allowed, each in their own carrier," and that a second pet needs a second seat and a second pet fee. The Contract of Carriage dated July 29, 2026, Section 10(d), says "a Passenger may not transport more than one pet per flight." The Contract of Carriage is the legally binding document, so call JetBlue and get the second pet confirmed on your reservation before you travel with two dogs.

How to book a dog on JetBlue: step by step

1. Check your route. Pets are accepted on all JetBlue domestic flights, but not to or from the UK, the EU, Barbados, or Trinidad and Tobago (Contract of Carriage, 2026). Flights involving codeshare or interline partners follow different rules (Sections 35 and 36).
2. Book early. Only six pets are allowed in-cabin per flight, across all passengers.
3. Add the pet to your reservation. The Contract of Carriage says payment must be made when you make the reservation; pets are added as an extra in the JetBlue booking flow, and TrueBlue points can be used.
4. Choose an eligible seat. Avoid Mint, exit rows, bulkheads and seats without under-seat stowage. JetBlue recommends a window or aisle seat.
5. Gather paperwork. Use the USDA APHIS pet travel tool, CDC rules and the IATA database for your destination (see below).
6. Check in. Once the pet fee is paid and the pet is confirmed, you can check in 24 hours before departure online, in the JetBlue app or at a kiosk.
7. Collect your JetPaws bag tag. At the airport, visit the full-service counter or speak with a crewmember to get the JetPaws tag for the carrier.

What happens at the airport and TSA?

JetBlue's help page (2026) explains that your dog must stay inside its closed, zipped carrier throughout the airport. At the Transportation Security Administration (TSA) checkpoint, you will be asked to take your dog out and carry it through the screening equipment while the empty carrier is inspected; the animal never goes through the X-ray machine. If you cannot hold your dog, it will receive a secondary visual and physical inspection.

Pet relief areas vary by airport, and JetBlue warns that you may need to leave the secure area and re-clear security if your dog needs to relieve itself. Pet strollers count as carry-on items.

Rules on board

• The carrier must be under the seat in front of you for taxi, takeoff and landing.
• During the flight you may hold the carrier on your lap, but the dog must stay inside it.
• If you bought an extra seat, the carrier may sit on that seat in cruise, but must go under the seat for taxi, takeoff and landing.
• You may unzip the carrier briefly to feed or assist your dog, then must zip it again.

What documents does my dog need to fly JetBlue?

JetBlue does not issue health certificates, and it makes the traveler responsible for meeting destination laws, "including furnishing valid health and rabies vaccination certificates when required" (Contract of Carriage, 2026).

Domestic flights

According to JetBlue (2026), vaccination requirements for travel within the U.S. vary by state, and Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets. JetBlue directs travelers to the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) pet travel tool, noting that tool does not override JetBlue's own policies.

Dogs entering or returning to the United States

The U.S. Centers for Disease Control and Prevention (CDC) is the primary authority for dog imports, USDA APHIS confirms on a page last modified March 20, 2026. Since August 1, 2024, the CDC requires that dogs that have only been in dog-rabies-free or low-risk countries in the previous six months arrive with:

• a receipt for the free CDC Dog Import Form, one per dog, valid for six months;
• a microchip readable by a universal scanner;
• a minimum age of six months at entry; and
• a healthy appearance on arrival.

Dogs vaccinated in the U.S. that have visited a country the CDC classifies as high-risk for rabies need additional paperwork. USDA APHIS (2026) says these dogs need a Certification of U.S.-Issued Rabies Vaccination form, submitted by a USDA-accredited veterinarian before the dog leaves the United States. Plan this before booking a Caribbean or Latin American trip.

International destinations

JetBlue points travelers to the International Air Transport Association (IATA) online database for each country's pet import rules. Remember that JetBlue's own policy is stricter than many governments': even if the UK's or an EU country's pet entry rules would allow your dog, JetBlue will not carry pets on those routes (Contract of Carriage, Section 34, 2026).

Service dogs and emotional support animals

Trained service dogs follow a separate policy. Under JetBlue's Contract of Carriage (2026), service animals fly free, up to two per qualified individual with a disability. They must be harnessed, leashed or tethered, fit within the passenger's foot space, and cannot occupy a seat. If you booked more than 48 hours before departure, JetBlue requires the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form at least 48 hours in advance. Animals in training are not carried. Emotional support animals are treated as pets and must meet the in-cabin pet rules above.

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

Searchers sometimes mix up airline pet policies, government pet passports and digital animal ID records, so to be clear: nothing in JetBlue's policy asks for, or mentions, an Animal Passport record. The documents that matter for a JetBlue trip are JetBlue's pet booking and JetPaws tag, any destination health or rabies certificates, and, for dogs entering the U.S., the CDC Dog Import Form and microchip.

Animal Passport is a different product. It is a digital animal and livestock passport that identifies an animal by its muzzle print, which is unique like a fingerprint. A phone captures the muzzle, and the record binds the owner, breed, estimated age (from a dental photograph, with a confidence score), body condition score from 1 to 5 (from a side-profile photo), and vaccination history. It was used in livestock flood rescue in Pakistan in August 2025 so farmers could reclaim animals after paper tags washed away. It is not a government-issued travel document and does not replace an airline booking, a veterinary health certificate or a CDC form. More on animal identification is on the Animal Passport blog.

Practical tips before you fly JetBlue with your dog

• Have your dog spend time in the carrier at home for a few weeks so it is calm inside it.
• Measure the packed carrier against the 17 x 12.5 x 8.5 inch limit.
• Screenshot the pet confirmation on your reservation, especially for two-pet bookings.
• Look up pet relief areas at your departure and connecting airports.
• For any trip leaving the U.S., talk to a USDA-accredited veterinarian as soon as you decide to travel, as USDA APHIS advises.

Policies change. This article reflects JetBlue, CDC and USDA APHIS pages reviewed on October 1, 2026. Confirm fees and route eligibility in the JetBlue booking flow before you pay.
