JetBlue’s cancellation policy depends on the type of fare purchased. If you buy a refundable fare, you are eligible for a full refund to your original form of payment as long as you cancel before the scheduled departure time. For non-refundable fares, such as Blue, Blue Plus, Blue Extra, and Mint, you can cancel without a fee and receive a travel credit for the full amount if you cancel before departure. Blue Basic fares are more restrictive and come with cancellation fees. If you cancel a Blue Basic ticket, a $100 fee applies for flights within the U.S., Caribbean, Mexico, or Central America, and a $200 fee applies for other international flights. The remaining balance after the fee is issued as a travel credit. JetBlue’s 24-hour cancellation policy allows you to cancel any flight within 24 hours of booking for a full refund, as long as the booking was made at least seven days before the scheduled departure. This applies to all fare types. If you do not cancel a non-refundable ticket before the flight departs, the entire value of the ticket is forfeited. Travel credits issued after cancellation can be used toward future JetBlue flights and are generally valid for one year from the date of issuance. Refunds for eligible tickets are usually processed back to the original form of payment within 7 to 10 business days. If a flight is canceled by JetBlue, you may be entitled to a full refund or travel credit regardless of your fare type. In special circumstances such as death or serious illness, JetBlue may provide a refund even for non-refundable tickets if proper documentation is submitted. Changes and cancellations can be made online through the JetBlue website or mobile app. Some transactions made through the call center may include an additional service fee. It's important to check your specific fare rules at the time of booking to understand the exact cancellation terms.
