JetBlue and Dogs: What the 2026 Pet Policy Really Allows

JetBlue and dogs: JetBlue Airways allows only small dogs (and cats) to fly, and only in the cabin, inside a carrier no larger than 17 x 12.5 x 8.5 inches that fits under the seat in front of you. There is no cargo or checked-pet option, large dogs are not accepted, a pet fee is charged each way, and JetBlue caps cabin pets at six per flight. Pets cannot fly on JetBlue to or from the United Kingdom or European Union.

In short, JetBlue's dog policy is a cabin-only program for small dogs, which JetBlue brands as JetPaws. Trained service dogs fall under separate federal rules. This guide is current as of October 2026. It is built from JetBlue's own help page, the JetBlue Airways Contract of Carriage (version dated July 29, 2026), and 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).

Does JetBlue allow dogs on planes?

Yes, but only small ones. JetBlue's help page, as of October 2026, says: "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 adds, "No large dogs are accommodated on JetBlue."

The JetBlue Airways Contract of Carriage (2026) is stricter still in its wording: "No animals are allowed to be transported on Carrier as checked baggage; however, Carrier will permit small dogs and cats to be transported by Passengers in-cabin (no other animals are allowed)." So JetBlue has no cargo hold option for a medium or large dog. If your dog can't stand up and turn around inside a compliant under-seat carrier, it can't fly JetBlue as a pet.

JetBlue does not publish a weight limit. The test is whether the dog fits the carrier, not what the scale says.

JetBlue dog carrier size requirements

According to JetBlue's help page (2026), pet carriers must meet these rules:

• Maximum dimensions: 17 in L x 12.5 in W x 8.5 in H (43.18 cm x 31.75 cm x 21.59 cm).
• Leak-proof bottom and good ventilation.
• Soft-sided and hard-sided carriers are both accepted.
• Carriers that could let the pet escape are refused.
• One pet per carrier, and the dog must be able to stand up and move around easily inside it.
• JetBlue sells carriers at the airport ticket counter for USD $55 while supplies last, according to its help page (2026).

Height is the tightest limit. At 8.5 inches, JetBlue's carrier height is lower than many "airline-approved" carriers sold online. A soft-sided bag that can flex under the seat is usually easier to fit than a rigid crate, even though JetBlue technically accepts both.

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

JetBlue charges a pet fee for each direction of travel. The JetBlue Airways Contract of Carriage (2026) says the fee must be paid when you make the reservation. The help page we reviewed in October 2026 did not show a dollar amount, so the figure below comes from secondary sources, and they don't all agree:

• USD $150 each way is the current figure listed by Paws On Board (policy last updated April 20, 2026) and other 2026 pet-travel guides.
• USD $125 each way appears in older coverage, which suggests JetBlue raised the fee at some point.

Treat $150 each way ($300 round trip) as the working estimate and confirm the exact price in the Extras section when you book. According to Paws On Board (2026), you can pay the fee during booking or later in Manage Trips, or with TrueBlue points before check-in. If you bring a second pet, JetBlue's help page (2026) says you need a second seat and a second pet fee.

JetBlue pet rules at a glance

One inconsistency is worth knowing about. JetBlue's help page allows two pets per traveler if you buy a second seat, but the Contract of Carriage (July 2026) says "A Passenger may not transport more than one pet per flight." If you plan to fly with two dogs, get the second pet confirmed in writing by JetBlue before you travel.

How to book a dog on JetBlue: step by step

1. Measure your dog and carrier. Confirm the carrier is within 17 x 12.5 x 8.5 inches and that your dog can stand and turn around in it with the carrier closed.
2. Book early. Because the Contract of Carriage (2026) limits each flight to six cabin pets, popular routes can run out of pet space.
3. Add the pet in Extras. Pay the pet fee when you book, as the Contract of Carriage requires.
4. Pick an eligible seat. JetBlue's help page (2026) bars travelers with pets from emergency exit rows, bulkhead seats, Mint and any seat with restricted under-seat stowage. It recommends a window or aisle seat.
5. Check destination paperwork. Use the USDA APHIS pet travel tool and CDC guidance (see below). JetBlue's help page notes that Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets.
6. Check in and collect your JetPaws tag. Once the pet is confirmed, you can check in online up to 24 hours before departure. Then get the JetPaws bag tag at the full-service counter, according to JetBlue's help page (2026).
7. Clear TSA screening. You'll carry your dog through the metal detector while the carrier is X-rayed. JetBlue's help page states that the animal itself is never put through the X-ray machine.

What happens at the airport and on board

JetBlue's help page (2026) says your dog must stay inside the zipped carrier in the airport and on the plane. You may unzip it only briefly to feed or help the dog. During taxi, takeoff and landing, the carrier must be under the seat in front of you. During the flight you may hold the carrier on your lap. If you bought an extra seat, the carrier can sit on that seat, but the dog stays inside it.

Pet relief areas vary by airport. JetBlue warns that you may need to leave the secure area and go back through security if your dog needs to relieve itself, so build that time into your connection.

JetBlue's own help page also contradicts itself on one point. One section says the pet and carrier count as your personal item, while another says they count as your carry-on item. In both cases the carrier must fit under the seat, so plan to use that space for your dog.

Can you fly internationally with a dog on JetBlue?

Only on some routes. Section 34 of the JetBlue Airways Contract of Carriage (2026) says that for travel to and from the United Kingdom and the European Union, "pets will not be permitted by Carrier." It also bars live animals and pets on flights to Barbados and Trinidad and Tobago because of local government requirements. Pets are also not accepted on interline or codeshare bookings, according to Paws On Board (2026).

For other international routes, JetBlue's help page says customers are responsible for understanding import rules. It points to three official tools: the USDA APHIS pet travel tool, the CDC dog import pages, and the International Air Transport Association (IATA) country database. JetBlue also notes that APHIS requirements "do not override JetBlue's policies."

Bringing a dog back into the United States

The CDC is the primary authority for dogs entering the United States, according to USDA APHIS (page last modified March 20, 2026). For dogs that have been only in dog rabies-free or low-risk countries during the previous 6 months, the CDC (rules effective August 1, 2024) requires:

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

If your dog has been in a high-risk country for dog rabies during the past 6 months, stricter CDC requirements apply. For example, a U.S.-vaccinated dog needs a Certification of U.S.-Issued Rabies Vaccination submitted by a USDA-accredited veterinarian before departure, according to USDA APHIS (2026). The CDC states that an unvaccinated dog coming from a high-risk country will not be allowed to enter.

Service dogs and emotional support animals on JetBlue

Trained service dogs are not pets under JetBlue's rules. The JetBlue Airways Contract of Carriage (2026) says JetBlue carries service animals for qualified individuals with a disability at no charge, with up to two per person. The animals must be harnessed, leashed or tethered, and must fit in the passenger's foot space. If you booked more than 48 hours before departure, JetBlue requires the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form 48 hours in advance. Animals in training are not carried.

Emotional support animals are not treated as service animals. Paws On Board (2026) notes that JetBlue stopped accepting them as such after the 2021 DOT rule change, so an emotional support dog must meet the regular pet rules: small, in a carrier and fee paid.

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

Travelers searching for "jetblue and dogs" often also search for "pet passport." The terms get mixed up, so it helps to separate them:

• Airline and government pet documents include rabies certificates, the CDC Dog Import Form, USDA-endorsed health certificates and destination-country forms. These are the papers an airline or border official may ask for. They come from veterinarians and government agencies, not from Animal Passport.
• Animal Passport is a digital animal and livestock identity record based on muzzle biometrics. An animal's nose print is unique, much like a fingerprint. Using a phone, an owner captures the nose print and builds a record that links the owner, breed, estimated age (from a dental photograph, with a confidence score), a 1 to 5 body condition score from a side-profile photo, and vaccination history.

Animal Passport is not a government-issued travel document, is not accepted in place of a CDC form or a veterinary health certificate, and has no role in JetBlue's pet check-in. Its main field use has been livestock. During the August 2025 floods in Pakistan, farmers used it to reclaim animals after paper ear tags washed away. That distinction matters for travel too: USDA APHIS (2026) notes that animals considered livestock or poultry, such as pigs or chickens, do not qualify for pet travel at all and fall under separate import and export rules.

Bottom line

JetBlue works well for small dogs that fit a 17 x 12.5 x 8.5-inch under-seat carrier. It doesn't work for large dogs, for anyone needing cargo transport, or for trips to the UK or EU. Book early because of the six-pet cap, budget roughly $150 each way, and check the CDC and USDA APHIS requirements before any international trip. Because airline fees and wording change, confirm the details on JetBlue's official pet page before you fly.
