Yes, JetBlue allows passengers to cancel their flights or Help 1-808-865-4114, with policies that vary based on the fare type. Most JetBlue fares—Blue, Blue Plus, Blue Extra, and Mint—can be canceled without a fee, and the value will be returned as a travel credit or refund depending on the ticket’s refundability. Basic Blue fares are the exception; they are non-refundable and cannot be changed or canceled after the 24-hour booking window. If you cancel a refundable ticket, you'll get a full refund to your original payment method. For non-refundable tickets, travel credits are issued for future use within 12 months. You can cancel your flight online, via the mobile app, or by contacting JetBlue’s customer service. JetBlue also allows cancellations without penalty if they initiate the cancellation or significantly change your itinerary. Be sure to cancel before your scheduled departure, as no-shows will typically result in the loss of the ticket value.
