If you cancel a JetBlue flight, whether you get a refund depends on the type of ticket you bought and when you cancel. For refundable tickets, you can cancel anytime before the flight and get a full refund to your original payment method. If you don’t cancel before the flight, the money usually turns into a travel credit valid for one year. For non-refundable tickets, if you cancel before the flight, you pay a cancellation fee, and the rest of the money becomes a travel credit to use within one year. If you don’t cancel before the flight, you lose the entire amount paid. Blue Basic fares are the most restrictive; you can cancel within 24 hours of booking without a fee if the flight is more than seven days away. After that, canceling costs a fee, and the rest of the money becomes travel credit. JetBlue also has a 24-hour cancellation policy that lets you cancel any ticket within 24 hours of booking for a full refund, as long as the flight is at least seven days away. In special cases like illness or death, JetBlue may offer a full refund or credit if you provide proof. You can cancel your flight online, through the app, or by calling customer service. Always check your ticket type and cancel early to avoid fees and to get the best refund or credit option.
