JetBlue (B6) is one of the US carriers Cooper and I have considered for East Coast routes — their cabin pet program is well-documented. JetPaws is the formal name. Cabin pets only (no checked baggage option), with a per-segment fee and an in-cabin pet count that's actively managed on most routes.

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 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 $125 USD for cabin pets in each direction. The fee is per pet, per one-way segment, billed at booking through the JetPaws flow or at the airport counter. Multi-segment itineraries multiply the base. Pay during booking through Manage Reservations; the fee is non-refundable once added to the reservation, including for traveller cancellations.
JetBlue is a clean choice for US cabin pet travel with a fixed fee and a documented per-flight cap. Your plan answers two questions: does the carrier fit the under-seat space for the aircraft type, and is the route on JetBlue's accepted-pet list. With those locked, JetPaws handles the booking through a single flow.
