Your right to cancel with JetBlue will depend on the type of booking you have made. For flights only, if you cancel within 24 hours of your booking, you will not be subject to a cancellation fee and will receive the full amount of your payment. On nonrefundable fares, you may receive some of your money back in the form of a travel credit you can use against future bookings, also some of this will be taken as a cancellation fee. On refundable fares, you will be able to claim a full refund back to your original payment method if cancelled prior to the scheduled departure. On JetBlue Vacation packages, no cancellation fee applies to flight and hotel bookings, although hotel policies vary by hotel. Vacation bookings are nonrefundable, so the amount will come back to you in the form of a travel credit to use against a future booking, up to one year in advance.
