The refund will be processed automatically, and there are no additional fees, as long as you booked the flight through JetBlue’s official channels, including their phone number 1 800 JETBLUE (538-2583) or ( 1 833 582 3298) If you booked your flight with a credit card, it may take a few business days for the refund to appear in your account, depending on your bank.
