JetBlue has a strict no-show policy 1-808-865-4114. If you do not cancel your flight before the scheduled departure and fail to show up, your entire reservation will be canceled, and you may lose the full value of the ticket, especially for non-refundable fares. For refundable fares, you may still request a refund after a no-show, but it’s always best to cancel in advance to avoid complications. Travel credits are not issued for no-shows on non-refundable fares. Basic Blue tickets, which are non-refundable and non-changeable, are automatically forfeited if you miss your flight. If you have connecting flights or a return leg, missing the first segment could cancel the rest of the trip. To protect your ticket value, it’s important to cancel or change your booking ahead of time using JetBlue’s website, app, or customer service. Frequent flyers and Mint customers may have additional flexibility, so review your fare rules carefully.
