Yes, JetBlue allows you to cancel your flight within 24 hours of booking for a full refund, provided the reservation is made at least seven days before the flight’s scheduled departure. This policy offers flexibility and peace of mind for travelers. For more details, check JetBlue’s fare rules or contact their customer service.
