JetBlue Pet Policy for Dogs and Cats

JetBlue flies pets in the cabin only. A small dog or cat travels in a carrier under the seat in front of you, and JetBlue says it does not book dogs or cats in cargo and accommodates no large dogs. The short answers below come from JetBlue’s traveling with pets page and its pet help page, both read October 21, 2026.

A dog too big for that carrier cannot fly JetBlue at all. It travels as cargo with another airline or goes by road, and our dog transport service arranges either one.

That makes JetBlue a simple airline to plan around and an impossible one to negotiate with. The decision is made by a tape measure, and the measurement that matters is height, because JetBlue allows a carrier only 8.5 inches tall.

JetBlue accepts small dogs and cats in the cabin. JetBlue says it does not book dogs or cats in cargo, only in the cabin. If your dog does not fit under the seat in front of you, JetBlue is not an airline you can use for that animal at any price. Our airline crate size calculator works out IATA’s minimum inside dimensions for your dog or cat’s travel crate.

Your pet and its carrier together count as one personal item, not as an extra piece of baggage, which is worth knowing if you were planning to bring a bag as well. Only one animal may travel in each carrier, and JetBlue asks that the animal be able to turn around comfortably inside it with the carrier closed.

The animal stays in a zipped carrier for the whole time it is with you, at the airport and on the aircraft. You may unzip it to feed or assist the animal and then it goes back. Unaccompanied minors cannot travel with a pet at all.

The pet fee is $150 each way, so $300 for a round trip. You add it in the Extras section while booking, or afterwards in Manage Trips on the website or My Trips in the app.

JetBlue lets you pay the pet fee with TrueBlue points any time before check-in. That does not make the animal cheaper to move, but it is a real option if you are sitting on a balance.

If you bring a second animal you pay a second fee and buy a second seat, so two pets on one trip is two fees plus a fare rather than a discounted pair.

JetBlue publishes one maximum carrier size: 17 inches long by 12.5 inches wide by 8.5 inches high (43.18 by 31.75 by 21.59 cm), and it must be an FAA-approved carrier. Our pet carrier size checker sets IATA’s minimum for your dog or cat beside the under-seat limits that US and Canadian airlines publish.

The height is the number to look at. JetBlue allows 8.5 inches. Delta says the aircraft sets its in-cabin maximum, and recommends a soft-sided kennel of 18 by 11 by 11 inches. A carrier bought to that recommendation is two and a half inches too tall for JetBlue. United publishes its own in-cabin limits on its pets page, so check a carrier bought for United against JetBlue’s 8.5 inches before you book. A dog that flies comfortably on one of those carriers may not have a legal carrier on this one, and the difference is not marginal.

If you do not already own something that fits, JetBlue sells carriers online and at the JFK Terminal 5 ticket counter, subject to availability and by credit card only, and its pet help page gives the airport price as $55, as of October 2026, with quantities limited. Buying at the airport is a fallback rather than a plan, because a carrier your animal has never been inside is the wrong thing to introduce on a travel day.

A traveler may bring up to two pets, each in its own carrier, and the second one requires both a second seat and a second pet fee. The seat is not a courtesy, it is where the second carrier goes.

JetBlue also caps the whole aircraft at six pets per flight. That number is lower than it sounds once you consider how many people are trying to move an animal on a popular route in summer. The practical advice JetBlue gives is to book early, and it is the correct advice: the place is inventory and it does not come back.

Buying an extra seat does not mean the animal rides in it. During taxi, takeoff and landing the carrier goes under the seat in front of you like any other. For the rest of the flight you may hold the carrier on your lap or set it on the seat you bought. The animal itself is not permitted to sit on a seat at any point.

Pets travel in Main, EvenMore or BlueFirst, the cabins JetBlue’s pet page names. They are not permitted in Mint, JetBlue’s premium cabin, so booking Mint and adding an animal afterwards does not work.

Within Main, JetBlue will not assign you an exit row, a bulkhead seat, or any seat where the space under the seat in front is restricted. It recommends a window or aisle seat, which in practice is where the usable floor space is. Choose the seat when you book rather than at check-in, because the pet booking and the seat map interact and the good options go first.

This is the rule most likely to ruin an itinerary that looked fine when it was booked. JetBlue does not accept pets on interline or codeshare bookings, regardless of where or how the booking was made.

So a JetBlue flight number on a ticket is not enough. If the itinerary includes a partner-operated leg, or was issued as a single interline ticket across two airlines, the animal cannot travel on it even though every individual flight appears to allow pets. Check how the ticket is issued, not just which aircraft you are on, and book the JetBlue portion directly with JetBlue when an animal is involved.

JetBlue’s pet help page, read October 21, 2026, lists the routes where it accepts no pets at all, on flights to or from Colombia (BAQ, CLO, CTG and MDE), the Dominican Republic (POP, PUJ, SDQ and STI), Ecuador (GYE), Guatemala (GUA), Guyana (GEO), Haiti (PAP), Honduras (SAP), Trinidad and Tobago (POS), and the UK and Europe (AMS, BCN, CDG, DUB, EDI, LGW, LHR, MAD and MXP). A small dog in a carrier that fits still cannot fly JetBlue to London or Paris. On those routes the pet flies with another airline, which our international pet shipping service plans.

For its other destinations JetBlue says the requirements for dogs and cats vary by origin, destination, date of booking and date of travel. It puts the checking on the traveler, urges starting the import process at least 30 days before travel, and warns that failing to meet US entry requirements can end in refused entry.

That is honest and it is also the gap where a move goes wrong. The airline will carry the animal and will not tell you the destination will not accept it. The document work is a separate job from the booking, and on a US departure it runs through USDA APHIS endorsement. Our APHIS pet travel guide covers that side, and our cat cost guide covers what the document work adds to an international move.

Two absences are worth naming, because each one is a question people arrive with and JetBlue’s pet pages, read October 21, 2026, do not answer.

They publish no weight limit for the animal and no breed restriction for a cabin pet. The only age they mention is the CDC’s for a dog entering the United States, at least 6 months old. The carrier dimensions are the only stated test, which means a heavy but short cat and a light but tall puppy are treated differently by the only rule that exists.

Do not read those absences as permission. A destination sets its own minimum age and the CDC sets one for dogs entering the United States, so an animal JetBlue would carry may still be too young to land where it is going. When the airline is silent, the government rarely is.

One name is worth knowing. JetBlue’s pet program used to be branded JetPaws, and a great deal of the advice online still describes it that way. On JetBlue’s current pet help page the name survives on the JetPaws bag tag: with the pet fee paid and the pet confirmed, you can check in online from 24 hours before the flight, then collect the tag at the full-service counter, or from a crewmember in the self-service lobby, and attach it to the carrier.

On a JetBlue route the work is mostly front-loaded, because the airline gives you few levers once the booking exists. We measure the animal against the 8.5 inch height before anything is booked, since that single number decides whether JetBlue is possible at all. We check how the ticket is issued rather than which aircraft is flying, because the codeshare rule voids the plan silently. And we count backwards from the destination’s document deadlines rather than from the flight, since JetBlue carries the animal without checking whether it can land.

Where the animal is too tall for the carrier limit, we say so early and look at the carriers that still run a live animal program on the route rather than trying to make JetBlue work.

Our team holds IATA Live Animals Regulations certificates. Documentation for departures from the United States follows USDA APHIS requirements.

The three differ in the details that decide a booking. JetBlue says it does not book dogs or cats in cargo, only in the cabin. Delta ships pets only for active US military and State Department Foreign Service personnel with permanent change of station orders. United publishes its own policy on its pets page.

The carrier limit is where they genuinely differ. JetBlue’s 8.5 inch height is lower than the 11 inches of the soft-sided kennel Delta recommends for most of its aircraft. United publishes its own limits on its pets page. For a dog near the line that is the whole decision.

The caps differ too. JetBlue holds the whole aircraft to six animals, and Delta sets a limit on the total number allowed on each flight. Check United’s pets page for its own caps.

Compare JetBlue’s fee above with the one in our Delta pet policy guide, then let the carrier limit and the route decide. Our Delta pet policy guide carries that airline’s current fees and conditions. Our United pet policy guide sets out what to check on the airline’s own page.

No. JetBlue states that no large dogs are accommodated and that no dogs or cats are carried in cargo. The only route onto a JetBlue aircraft is a carrier that fits under the seat in front of you, so for a larger dog the answer is a different airline rather than a different fare.

JetBlue states the pet fee as $150 each way, as of October 2026, which is $300 for a round trip. It can be added during booking or later in Manage Trips, and it can be paid with TrueBlue points any time before check-in.

No larger than 17 inches long by 12.5 inches wide by 8.5 inches high, and it must be FAA-approved. The 8.5 inch height is lower than the 11 inches of the soft-sided kennel Delta recommends, so a carrier bought to that recommendation will not meet JetBlue’s limit. United publishes its own carrier limits on its pets page.

Yes, up to two per traveler, each in its own carrier. You pay a second pet fee and buy a second seat for the second carrier. The aircraft is capped at six pets in total, so the constraint is usually the flight rather than your booking.

JetBlue’s pet pages, read October 21, 2026, publish neither. They state only that the animal must be a small dog or cat and must fit in a carrier within the published dimensions. Note that a destination may impose its own breed and age rules even where the airline does not.

No. JetBlue does not accept pets on interline or codeshare bookings, regardless of where or how the booking was made. Confirm how the ticket is issued before you buy it, because an itinerary can carry a JetBlue flight number and still fall under this rule.

Every figure here comes from JetBlue’s own traveling with pets page and its pet help page, read again on October 21, 2026. That includes the $150 each way fee, the 17 by 12.5 by 8.5 inch carrier limit and the carrier rules, the $55 airport carrier, the two pets per traveler and six per flight caps, the cabins pets may use and the seating exclusions, the routes where pets are not accepted, the interline and codeshare rule, the JetPaws bag tag, and the statement that no dogs or cats are carried in cargo. Airline pet policy changes more often than almost anything else in this field, so confirm the fee and the carrier limit with JetBlue before booking, and treat any summary of an airline policy, this one included, as a starting point rather than the last word.
