JetBlue’s refund policy depends on the fare type and when you cancel. You can cancel within 24 hours of booking for a full refund if your flight is at least seven days away, no matter the fare type. After 24 hours, refundable fares can be fully refunded if canceled before the flight. If canceled after departure, any unused funds become travel credit valid for 12 months. Non-refundable fares can only be canceled for travel credit if canceled before departure, minus cancellation fees. If you do not cancel before the flight, you lose the ticket value. Blue Basic fares have a $100 cancellation fee for flights within North America, Central America, or the Caribbean, and $200 for other international flights. Other fare types like Blue, Blue Plus, Blue Extra, and Mint may have different fees or rules. To avoid extra fees, cancel or change flights online. Phone cancellations may have a $25 service fee. If JetBlue cancels your flight, you get a full refund regardless of fare type. If you miss your flight, you can rebook a new flight within 24 hours at no extra cost. If you booked through a travel agency, you must contact them for cancellations or refunds. Always check your ticket’s fare rules to understand cancellation and refund eligibility.
