JetBlue Dog Policy: What Small Dogs Need to Fly in Cabin

As of September 2026, the JetBlue dog policy lets only small dogs (and cats) fly in the cabin inside an approved under-seat carrier—JetBlue does not take large dogs or pets as checked baggage. The carrier may not exceed 17" L × 12.5" W × 8.5" H, the pet must stay zipped inside, and a pet fee applies when you reserve space. Service dogs follow a separate U.S. Department of Transportation (DOT) process. Rules and dollar fees can differ between JetBlue’s help pages and its Contract of Carriage, so verify your booking before you travel.

This guide is published by Animal Passport for travelers researching airlines and flying with pets. It summarizes JetBlue’s published cabin-pet rules, flags where official JetBlue documents disagree, and points to primary government sources for health paperwork. It is not legal, veterinary, or booking advice.

What is the JetBlue dog policy?

The JetBlue dog policy is JetBlue Airways’ set of rules for transporting companion dogs (and cats) as in-cabin pets on JetBlue-operated flights. According to JetBlue’s Traveling with Pets help page, only small dogs and cats may travel in an Federal Aviation Administration (FAA)–approved pet carrier that fits under the seat; no large dogs are accommodated, and JetBlue does not accept pet remains in the cabin or as cargo.

JetBlue’s Contract of Carriage (including the June 1, 2026 and September 6, 2024 editions reviewed for this article) states that no animals are transported as checked baggage, that only small dogs and cats may travel in-cabin, that pets are not permitted in Mint, that unaccompanied minors may not travel with a pet, and that a maximum of six in-cabin pets may travel on any flight.

Cabin-only: no checked dogs on JetBlue

Unlike some carriers that still move pets in the hold, JetBlue’s Contract of Carriage says animals are not accepted as checked baggage. If your dog cannot fit JetBlue’s under-seat carrier rules, JetBlue’s published pet policy does not offer a cargo alternative on JetBlue itself. Plan another airline, ground transport, or a different travel date—do not assume a last-minute exception.

United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) publishes separate Animal Welfare Act guidance for dogs and cats presented for air transport (kennel size, age, labeling, and related standards). Those USDA APHIS “Pets on Planes” materials are aimed largely at animals moving as cargo or under commercial transport rules; JetBlue’s cabin-pet product still requires you to meet JetBlue’s own carrier and behavior rules first.

Carrier size, fit, and what you can buy at the airport

JetBlue’s Traveling with Pets page lists these cabin-carrier requirements:

• Maximum dimensions: 17" L × 12.5" W × 8.5" H (43.18 cm × 31.75 cm × 21.59 cm)
• Leak-proof bottom and good ventilation
• Soft-sided or hard-sided carriers accepted
• No containers that allow escape
• Only one pet per carrier
• Pet must be able to stand up and turn around comfortably when the carrier is closed

JetBlue states that pet carriers may be purchased at the airport ticket counter for USD $55, with quantities limited, and that carriers may also be purchased online or at the John F. Kennedy International Airport (JFK) Terminal 5 ticket counter pending availability (credit card only). Measure your dog in a closed trial pack at home: the 8.5-inch height limit is often the binding constraint for soft carriers.

On JetBlue’s fare pages, an approved pet carrier counts as your personal item. Travelers who have added a pet may still bring a carry-on bag that fits overhead, while the pet carrier fills the under-seat personal-item slot.

Pet fee: what JetBlue documents say (and where they diverge)

JetBlue’s Traveling with Pets help page refers to “the pet fee” but does not publish a dollar amount on that page. JetBlue’s Optional Services and Fees page (reviewed for this article) likewise does not list a standalone pet-fee line item among bag, seat, and amenity charges.

A JetBlue Contract of Carriage PDF still hosted on JetBlue’s site (document dated September 6, 2024 in the durable homepage assets) states that the charge for transporting a pet in-cabin is One Hundred and Twenty-Five Dollars ($125) per pet, each way, paid when the reservation is made. JetBlue’s June 1, 2026 Contract of Carriage keeps the same one-pet-per-passenger structure and six-pet flight cap but replaces the numbered dollar amount with the phrase that “a fee will apply” and must be paid at reservation time.

Because JetBlue’s own materials no longer agree on a single published dollar figure across help, fees, and Contract of Carriage editions, treat any third-party “$150” claim as unverified until JetBlue shows that amount in your booking flow. Confirm the live fee in Extras during booking or in Manage Trips before you travel.

How many dogs per passenger—and per flight?

Here JetBlue’s customer-facing help page and its Contract of Carriage disagree, so both should be cited.

• Help page: A maximum of two pets per traveler is allowed, each in its own carrier; a second pet requires a second seat and a second pet fee.
• Contract of Carriage (2024 and 2026 editions reviewed): A passenger may not transport more than one pet per flight; a maximum of six pets may travel in-cabin on any flight.

Operationally, cabin pet space is limited. Add the pet early, keep confirmation of payment, and do not assume a second dog will clear if flight inventory is already full. If your itinerary includes a codeshare or interline partner, JetBlue’s Contract of Carriage directs you to partner-specific sections because acceptance rules can differ.

Seating, onboard behavior, and airport steps

JetBlue’s Traveling with Pets page states that customers traveling with pets cannot sit in an emergency exit row, bulkhead seat, Mint seat, or any seat restricted for under-seat stowage. JetBlue recommends a window or aisle seat. The pet must remain inside the carrier on board; the carrier goes under the seat ahead of you for taxi, takeoff, and landing. You may hold the carrier on your lap in flight. If you buy an extra seat, the pet in its carrier may sit on that empty seat during the cruise phase but must still stay inside the carrier and must stow under a seat for taxi, takeoff, and landing.

At the airport, after the pet fee is paid and the pet is confirmed, JetBlue says you may check in beginning 24 hours before departure online, in the JetBlue app, or at a kiosk. Collect a JetPaws® bag tag at a full-service counter or from a crewmember in the self-service lobby. The pet must stay inside its closed carrier in the airport. Pet relief areas vary by airport; you may need to exit and re-clear security.

For Transportation Security Administration (TSA) screening, JetBlue states that you present the animal to officers, the carrier may be searched, you typically hold the pet while the empty carrier is inspected, and animals are not placed through the X-ray machine. Secondary screening may apply if you cannot hold the animal through the checkpoint.

Pets vs service dogs vs emotional support animals

Companion pets under the JetBlue dog policy are not the same as service animals.

The U.S. Department of Transportation final rule Traveling by Air with Service Animals (published December 10, 2020; effective January 11, 2021) defines a service animal as a dog, regardless of breed or type, that is individually trained to do work or perform tasks for a qualified individual with a disability. The same DOT rule allows airlines to treat emotional support animals as pets rather than service animals. Psychiatric service dogs that are task-trained remain service animals under that definition.

JetBlue’s Contract of Carriage accepts service animals for qualified individuals with a disability at no charge (up to two per traveling passenger), requires harnessing/leashing/tethering, and—when the reservation is made more than 48 hours before the first departure—requires 48 hours’ advance notice with the U.S. Department of Transportation Service Animal Air Transportation Form. Animals in training are not transported under the CoC service-animal section reviewed. JetBlue’s Traveling with Pets page points readers to its Accessibility Assistance materials for the full service-animal process.

If your dog is an emotional support animal without disability-related task training, plan for JetBlue’s paid cabin-pet rules (small dog, carrier, fee, space)—not a free service-animal seat.

Domestic, Puerto Rico, U.S. Virgin Islands, and international paperwork

JetBlue’s Traveling with Pets page says JetBlue accepts pets on all domestic flights, that vaccination requirements inside the United States vary by state, and that Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets. Customers must obtain destination paperwork themselves.

JetBlue directs travelers to the USDA APHIS pet travel tool for destination-specific requirements, while noting that USDA APHIS destination rules do not override JetBlue’s own policies. For animals entering the United States, the U.S. Centers for Disease Control and Prevention (CDC) sets dog importation requirements based on rabies risk and vaccination history; CDC’s dog-import pages (updated August 1, 2024 in the materials reviewed) instruct travelers to use CDC’s Dog Importation Navigator and warn that unvaccinated dogs that have been in high-risk countries for dog rabies in the prior six months will not be allowed to enter the United States.

JetBlue’s Contract of Carriage Section 34 states that due to local government requirements, JetBlue does not permit transport of live animals and pets to Barbados or Trinidad and Tobago. For travel to and from the United Kingdom and the European Union, JetBlue’s CoC says pets will not be permitted, while service animals are permitted as required by applicable laws. Always re-check both JetBlue and destination authorities before purchasing nonrefundable tickets.

Practical checklist before you book

1. Confirm your dog is small enough for a closed carrier within JetBlue’s 17×12.5×8.5-inch limit.
2. Add the pet and pay the fee early; keep confirmation that pet space is reserved.
3. Avoid Mint, exit rows, bulkheads, and seats without under-seat stowage.
4. Check destination health rules via USDA APHIS and, for U.S. entry, CDC dog-import requirements.
5. If flying to Barbados, Trinidad and Tobago, the United Kingdom, or the European Union, re-read JetBlue’s Contract of Carriage pet restrictions for those markets.
6. If you need a service dog accommodation, use JetBlue’s accessibility process and the DOT form—not the pet-fee path.

How Animal Passport relates (and how it does not)

Animal Passport is a digital animal and livestock identity product that uses muzzle biometrics—the nose print is unique like a fingerprint—captured on a phone. A record can bind owner, breed, estimated age, body condition, and vaccination history. Age can be estimated from a dental photograph with a confidence score, and body condition can be scored 1–5 from a side-profile photo. The product was used in livestock flood rescue in Pakistan in August 2025 so farmers could reclaim animals after paper tags washed away. More field notes appear on the Animal Passport blog.

Animal Passport is not a JetBlue boarding credential, not an FAA or airline approval, not a USDA APHIS endorsement, not a CDC import clearance, and not an EU pet passport or Pet Travel Scheme (PETS) document. Airline cabin rules, DOT service-animal rules, and government import certificates remain separate official systems. Keep veterinary certificates and airline confirmations as your travel authorities require; use biometric ID only as a private ownership and history record where it is appropriate.
