Yes, JetBlue does allow passengers to cancel their booking within 24 hours of making the reservation, provided that the booking was made at least seven days before the scheduled departure. This is in line with the U.S. Department of Transportation’s 24-hour cancellation policy, which protects customers by allowing them a risk-free cancellation period. If your ticket meets these conditions, you can cancel your booking without incurring any fees, and a full refund will be issued to the original payment method.
