JetBlue Cancellation Policy is designed to give travelers flexibility when plans unexpectedly shift. If you cancel your flight within 24 hours of booking and at least 7 days before departure, you can receive a full refund. Beyond this period, most fares offer travel credits instead of refunds, with rules varying by ticket type. Blue Extra fares offer the highest flexibility, while basic fares may have restrictions. Same-day changes are also available for a fixed fee. By understanding JetBlue’s terms, passengers can make informed decisions, protect their travel investment, and adapt their schedules with minimal stress or financial loss.
