When you cancel a JetBlue flight, the refund you receive depends largely on the fare type and when you cancel. JetBlue offers refundable and nonrefundable tickets, each with different cancellation policies. Refundable tickets provide the most flexibility, allowing you to cancel your flight at any point before departure and receive a full refund back to your original payment method. This is ideal for travelers who want the option to change plans without losing money. However, if you miss canceling before the flight departs, even refundable fares may not qualify for a refund and could instead be converted into travel credit. Nonrefundable tickets, which are generally less expensive, come with stricter rules. If you cancel a nonrefundable ticket, JetBlue applies a cancellation fee—typically $100 for flights within North America, Central America, and the Caribbean, and $200 for international flights. After this fee is deducted, the remaining balance is returned as JetBlue Travel Bank credit, which must be used within one year and cannot be redeemed for cash. JetBlue also has a 24-hour cancellation policy that allows all passengers, regardless of fare type, to cancel their booking within 24 hours of purchase for a full refund, provided the flight departs at least seven days later. This policy gives travelers a chance to change their minds right after booking without penalty. Outside this 24-hour window, cancellation rules depend on your ticket type, and nonrefundable tickets will incur fees and offer credit instead of refunds. Additionally, if you fail to cancel before the scheduled departure and simply miss your flight, you lose the entire cost of the ticket, including any extras like baggage fees or seat selections. In certain cases such as serious illness or the death of a passenger or immediate family member, JetBlue may waive cancellation fees if you provide appropriate documentation like medical certificates or death notices. These exceptions are reviewed individually and are not guaranteed. In summary, if you want a full refund with no questions asked, purchasing a refundable ticket is the safest option. For those with nonrefundable tickets, it’s important to act quickly to cancel and take advantage of the 24-hour cancellation window to avoid losing money. Travel credit issued after canceling nonrefundable fares is a useful option, but it comes with expiration dates and cannot be turned into cash. Knowing JetBlue’s cancellation and refund policies before booking helps travelers make smart decisions and avoid unexpected losses. Canceling early and understanding the fees involved makes managing flight changes smoother. By staying informed about these rules, passengers can better plan their trips and protect their travel investments with JetBlue.
