JetBlue Airlines' cancellation policy offers flexibility depending on the fare type and timing of the cancellation. For Blue, Blue Plus, Blue Extra, and Mint fares, cancellations can be made without a fee if done at least 24 hours before the scheduled departure. However, passengers will receive a travel credit for future use, not a refund. For Blue Basic fares, cancellations are generally not allowed, but passengers can make changes for a fee and fare difference. Cancellations made within 24 hours of booking are eligible for a full refund if the flight is booked at least seven days before departure. If you need to cancel within 24 hours of your flight, fees will apply, and the remaining balance will be issued as a travel credit. For refundable fares, passengers can cancel anytime before the flight and receive a full refund to their original payment method. It's essential to review JetBlue's specific policies and conditions as they can vary and may be updated periodically.
