In the cabin: what JetBlue actually accepts
JetBlue's own rules, in plain English. Confirm the current details at jetblue.com.
JetBlue's in-cabin pet program is limited to small dogs and cats travelling in an FAA-approved carrier that fits fully under the seat in front of you. Large dogs are not accommodated on JetBlue at all, there's no larger-carrier fee, no bulk allowance, no workaround. If your dog doesn't fit under the seat, JetBlue doesn't have a way to fly it.
That's the hard ceiling for a JetBlue-approved carrier. Your pet needs to be able to stand and turn comfortably inside it, and it has to slide fully under the seat, not partway, not propped against your legs.
JetBlue doesn't state a minimum pet age on its pet-travel page, so we're not going to invent one. If you're travelling with a very young puppy or kitten, confirm directly with JetBlue or ask us to check before you book.
No checked or cargo pets, for anyone
The single biggest way a JetBlue pet trip falls apart before it starts.
Unlike some legacy carriers that still ship larger pets as cargo for military or State Department personnel on official orders, JetBlue's own pages describe no cargo-pet option of any kind, for anyone. Cabin is it.
There's no "check your dog like a bag" option at a JetBlue counter, pets aren't handled as checked baggage. If it doesn't fit in an under-seat carrier, it doesn't fly with JetBlue.
If your pet is too large for JetBlue's cabin limits, decide on another carrier or a ground-transport option well before your travel date, this isn't something that gets resolved at the airport.
Bringing a 2nd pet, the seat and fee rule
Easy to miss when you're booking for two animals.
JetBlue allows a maximum of 2 pets per traveler, and each pet needs its own carrier, you can't put two cats in one carrier to save a fee. The first pet travels at your feet for the standard pet fee. The second pet needs its own purchased seat next to you, on top of its own separate pet fee, it is not a second free carry-on, and it isn't half-price either. Budget for both a seat and a fee if you're travelling with two animals.
The pet fee, $150 each way
One of the few numbers JetBlue puts in writing. Confirm it hasn't changed before you book.
JetBlue charges $150 each way for an in-cabin pet. Fees like this change, so treat that figure as a starting point, confirm the current amount at jetblue.com, or call us and we'll verify it before anything is booked.
Don't confuse it with the carrier: if you show up without one, you can buy a carrier at the airport counter for $55. That's the price of the carrier itself, a separate charge from the $150-each-way pet fee, so don't mistake one for the other when you're budgeting. One piece of good news: the pet fee is refundable if you remove your pet from the itinerary before the scheduled departure time.
Where you can't sit with a pet onboard
This affects your seat selection, not just your pet's carrier.
Travelling with a pet rules out four seat types: an emergency exit row, a bulkhead seat, a Mint seat, or any seat without under-seat stowage. The carrier has to slide fully under the seat in front of you, and none of those seats provide that space, so if you've already picked one of them, plan to move before you check in. If we book your trip, we'll pick a compatible seat from the start.
Vaccination & destination documents
Requirements vary, confirm for your specific state or destination.
Within the US, vaccination requirements for a travelling pet vary by state, so what your home state requires may not match what your destination state expects. Two destinations have a documented requirement worth flagging specifically: Puerto Rico and the US Virgin Islands both require vaccination documentation for an arriving pet. Because these vary and can change, confirm the exact paperwork for your route before travel day rather than assuming your regular vet records are enough.
Service animals are different
Don't assume the pet rules above apply.
Trained service animals follow separate rules from pets on JetBlue, different carrier requirements, different fees, different documentation. We haven't independently verified JetBlue's current service-animal specifics closely enough to state them here, so we won't guess. Check JetBlue's own accessibility page at jetblue.com, or call us and tell us your situation, we'll route it correctly rather than treating a service animal like an ordinary pet.
Before you book, the checklist
A few minutes now avoids a pet turned away at the gate.
- Is your pet a small dog or cat? Large dogs aren't accommodated on JetBlue at all, no exceptions
- Does your carrier meet 17 x 12.5 x 8.5 in? It must be FAA-approved and fit fully under the seat
- Bringing a 2nd pet? It needs its own carrier, its own purchased seat, and its own pet fee
- Budgeted for the pet fee? $150 each way, confirm the current amount at jetblue.com before you fly
- Picked a compatible seat? Not an exit row, bulkhead, Mint seat, or any seat without under-seat stowage
Don't confuse the carrier price with the pet fee. The $55 counter price only buys you the carrier. JetBlue's actual pet fee is a separate $150-each-way charge, and it's worth confirming at jetblue.com since fees change. And remember: if your dog is too big for the cabin, JetBlue has no checked or cargo option at any price. Tell us your pet's size, your seat and your route, and we'll confirm what's possible before you book anything.
