When travellers consider canceling a booked trip, the first question that comes to mind is how to cancel, where to cancel, and how much it will cost. The cancellation charge is determined once the time and cause for cancellation are taken into account. The following guide will help you understand the Jetblue Cancellation Policy. If a traveler cancels a ticket beyond the 24-hour window, the Jetblue Cancellation Policy stipulates that a fee will be levied to the passenger's account. If the passenger fails to board the aircraft on time, Jetblue Airline will withhold a portion of the fare as a cancellation charge. The route taken by passengers is also important in determining the airline's cancellation fee.
