JetBlue Pet Policy: Check Your Pet and Route

JetBlue accepts only small dogs and cats as ordinary cabin pets, and the pet must travel in an FAA-approved carrier that fits comfortably under the seat (JetBlue pet policy, verified 1 October 2026). JetBlue does not accommodate large dogs under this pet policy (JetBlue pet policy). The carrier may not exceed 17 inches long by 12.5 inches wide by 8.5 inches high, and the pet must be able to stand and move around inside it with ease (JetBlue pet policy). Check the route next because JetBlue accepts pets on all domestic flights but excludes pets on specified international routes (JetBlue pet policy). Policy details were verified on 1 October 2026.

Does your pet and itinerary fit JetBlue's policy?

Use each row as a separate check. A yes in one row does not override a no in another.

For the wider decision process, read our airline pet policies guide. Our pet carrier backpack guide can help you compare designs, but JetBlue's dimensions and pet-fit wording still control the JetBlue check (JetBlue pet policy).

Which JetBlue routes accept ordinary pets?

JetBlue says it accepts pets on all domestic flights (JetBlue pet policy). For international travel, JetBlue says it does not accept pets on flights to or from the following destinations (JetBlue pet policy):

• Belize: BZE (JetBlue pet policy).
• Colombia: CTG and MDE (JetBlue pet policy).
• Dominican Republic: POP, PUJ, SDQ, and STI (JetBlue pet policy).
• Ecuador: GYE (JetBlue pet policy).
• Guatemala: GUA (JetBlue pet policy).
• Guyana: GEO (JetBlue pet policy).
• Haiti: PAP (JetBlue pet policy).
• Honduras: SAP (JetBlue pet policy).
• Trinidad and Tobago: POS (JetBlue pet policy).
• United Kingdom and Europe: AMS, BCN, CDG, DUB, EDI, LGW, LHR, MAD, and MXP (JetBlue pet policy).

For other international destinations, JetBlue says documentation requirements vary by country and places responsibility on the customer to understand the animal import requirements and obtain the necessary documents before travel (JetBlue pet policy).

What carrier does JetBlue allow?

JetBlue accepts either a soft-sided or hard-sided carrier (JetBlue pet policy). The carrier must meet all of these published conditions:

• The carrier cannot exceed 17 inches long by 12.5 inches wide by 8.5 inches high, or 43.18 by 31.75 by 21.59 centimeters (JetBlue pet policy).
• The carrier must have a leak-proof bottom and be well ventilated (JetBlue pet policy).
• JetBlue does not accept a container that allows a possible escape (JetBlue pet policy).
• Only one pet may travel in each carrier (JetBlue pet policy).
• The pet must be able to stand and move around inside the carrier with ease (JetBlue pet policy).
• The pet and carrier count as one carry-on item at the airport (JetBlue pet policy).

JetBlue also describes the pet and approved carrier as one personal item in its onboard guidance (JetBlue pet policy). If the difference between those two labels affects the rest of your baggage, resolve it against the live policy and your booking before travel.

What documents and vaccinations does JetBlue require?

For travel within the United States, JetBlue says vaccination requirements vary by state (JetBlue pet policy). JetBlue specifically says Puerto Rico and the U.S. Virgin Islands require vaccination documentation for pets (JetBlue pet policy).

For a pet leaving the United States, USDA APHIS tells travelers to contact a USDA-accredited veterinarian. APHIS says that veterinarian helps determine the destination country's entry requirements, including any needed vaccinations, tests, or treatments, and helps with a USDA-endorsed health certificate or other needed paperwork (USDA APHIS). Use our USDA pet travel route guide to identify the relevant official path, then follow the live authority page for the destination.

JetBlue says customers must understand each country's animal import requirements and obtain all necessary documentation before international pet travel (JetBlue pet policy). JetBlue's policy also says destination requirements do not override JetBlue's own rules (JetBlue pet policy).

For a separate coverage decision, Compare expat pet insurance. Insurance does not replace JetBlue's confirmation or the destination's entry requirements (JetBlue pet policy; USDA APHIS).

What happens at the airport and onboard?

JetBlue publishes these airport and cabin steps:

1. At the airport, visit the full-service counter or speak with a JetBlue crewmember in the self-service lobby to obtain a JetPaws bag tag for the carrier (JetBlue pet policy).
2. Present the animal to TSA officers at the security checkpoint, hold the pet while the carrier is inspected, and do not put the animal through the X-ray machine (JetBlue pet policy).
3. Keep the pet inside the closed or zipped carrier at the airport (JetBlue pet policy).
4. Keep the pet inside the carrier onboard, and place the carrier under the seat in front during taxi, takeoff, and landing (JetBlue pet policy).

Customers traveling with pets cannot sit in an emergency exit row, a bulkhead seat, a Mint seat, or a seat restricted for under-seat storage (JetBlue pet policy).

Can I take a 60 lb dog on a plane?

JetBlue's ordinary pet policy does not publish a weight allowance. It accepts only small dogs and cats in a qualifying under-seat carrier and says it does not accommodate large dogs (JetBlue pet policy). A 60 lb figure does not establish cabin eligibility under those rules (JetBlue pet policy). The dog would still have to fit JetBlue's small-dog, carrier-dimension, movement, and under-seat rules (JetBlue pet policy).

How strict is JetBlue with pet policy?

Use JetBlue's published acceptance checks instead of a subjective strictness rating. JetBlue limits ordinary pets to small dogs and cats, sets maximum carrier dimensions, requires the pet to stand and move with ease inside the carrier, excludes specified routes, and requires the pet to remain in the carrier at the airport and onboard (JetBlue pet policy). If the pet, carrier, route, or booking confirmation does not match those statements, this guide cannot treat the trip as eligible.

How do I add a pet to my JetBlue reservation?

The cited live page does not give an exact booking procedure (JetBlue pet policy). Confirm the current booking process directly with JetBlue before travel. For a second pet, JetBlue requires a second seat, with each pet in its own carrier (JetBlue pet policy).

Can I buy my pet a seat on JetBlue?

JetBlue allows a traveler to buy an additional seat, but the pet must remain inside its carrier (JetBlue pet policy). The pet and carrier must stay under the seat during taxi, takeoff, and landing (JetBlue pet policy). During the flight, JetBlue allows the carrier containing the pet to be placed on the additional purchased seat (JetBlue pet policy). JetBlue also requires a second seat when one traveler brings a second pet, with each pet in its own carrier (JetBlue pet policy).

Can I add a pet to my flight after booking?

The cited live page does not give an exact procedure for adding a pet after booking (JetBlue pet policy). Confirm the current booking process directly with JetBlue before travel.
