If you cancel a JetBlue flight, whether you get a refund depends on the fare type and timing. Refundable fares allow full refunds to the original payment method if canceled before departure. After departure, the value converts to JetBlue Travel Bank credit valid for one year. Non-refundable fares like Blue Basic require a cancellation fee—$100 for U.S., Mexico, Caribbean, and Central America flights, $200 for other international routes. After the fee, remaining value is issued as JetBlue Travel Bank credit. Missing a flight without canceling results in forfeiting the entire ticket value. JetBlue’s 24-hour cancellation policy allows full refunds if canceled within 24 hours of booking and the flight is at least seven days away, regardless of fare type. Cancellation can be done online via "Manage Trips" or by contacting customer service; phone cancellations may incur a $25 fee in addition to cancellation fees. Refund eligibility depends on fare type and cancellation timing, so reviewing ticket terms is important.
