Flying JetBlue with a dog? Good news up front: they welcome dogs right in the cabin with you, so no one rides down in the hold worrying alone. That single fact changed how relaxed I felt on our last move. Cooper has done this trip three times now, and having him under the seat beside me made all the difference. Here's what I wish someone had told me before we booked.
JetBlue's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Frequently asked
How many pets can I bring on JetBlue? JetBlue allows 6 in the cabin, per passenger. Each pet needs its own carrier. How much does it cost to fly a pet on JetBlue? On flights within Metropolitan France, JetBlue charges from 125 USD in the cabin, one way per pet. Longer routes cost more — price your exact itinerary. What if my flight is delayed past my health certificate validity? If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays. What happens if I forget a document? At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
JetBlue charges a cabin pet fee of 125 USD each way. Budget 250 USD for a round trip before any other costs. Pay the 125 USD fee at booking rather than at the gate. Confirm the charge applied to the reservation. Set aside the full 250 USD total upfront so the fee is covered on both legs of the route.
So that's JetBlue in a nutshell: cabin travel for your pup, a clear fee, and a booking window worth respecting. Every trip has its own quirks, though, depending on where you're headed and your dog's size. Before you book anything, let Pawgo build you a personalized plan for your exact route and pup. Cooper and I figured this out the hard way so you won't have to. You've got this.
