Pets are not accepted on interline/codeshare bookings, regardless of booking source (jetblue.com, travel agency, partner airline’s website, etc.).
You may book your pet online at jetblue.com or by calling 1-800-JETBLUE (538-2583).
JetBlue does not ship live animals as cargo or in the bellies of any aircraft.
Taking a pet to a foreign country involves preparation and planning far in advance of your departure date. Requirements for pet travel to a foreign country are set by the destination country. If you are you traveling to another country and bringing along your pet you’ll need to meet the animal health requirements of the country you are visiting.
