Travelling with pets is as easy and stress-free as possible. All pets must be in a secure and approved carrier, and must fit either under the seat in front of the customer, or in the overhead bin. JetBlue pet policy also requires that all pet owners provide proof of health and vaccination records from a veterinarian.
