JetBlue’s Flight Change Policy provides options to adjust your travel plans with varying fees based on your fare type. Most fares allow changes for a fee, plus any fare difference. However, Blue Basic fares are more restrictive and usually don’t permit changes. On the other hand, Blue, Blue Plus, and Mint fares offer more flexibility with lower change fees. All changes must be made before your original flight’s departure time. If you have a refundable fare, you can cancel and receive a full refund.
