If you cancel a JetBlue flight, your eligibility for a refund depends on the type of ticket you purchased and the timing of your cancellation.

Refundable Tickets
If you bought a refundable fare, you can cancel your flight at any time before departure and receive a full refund to your original payment method. This applies regardless of when you cancel, as long as it's before the scheduled departure time.

Non-Refundable Tickets
For non-refundable fares, the situation varies:

• Blue Basic: This is the most restrictive fare. If you cancel, you'll incur a cancellation fee of $100 for flights within the U.S., Mexico, the Caribbean, and Central America, or $200 for all other routes. After the fee is deducted, any remaining balance is issued as a JetBlue Travel Bank credit, valid for 12 months from the original ticketing date.

• Blue, Blue Plus, Blue Extra, and Mint: These fares can be canceled without a fee. The full amount paid is converted into a JetBlue Travel Bank credit, usable for future travel within 12 months. Note that unless you purchased a refundable fare or the refundable add-on during booking, cancellations for these fare classes do not return funds to your original payment method.

24-Hour Risk-Free Cancellation
JetBlue offers a 24-hour risk-free cancellation policy. If you book your flight at least seven days before departure, you can cancel within 24 hours of booking and receive a full refund to your original form of payment.

Special Circumstances
In cases of illness, injury, or death in the family, JetBlue may consider refunding non-refundable fares on a case-by-case basis. You'll need to provide documentation to support your request. There's no guarantee a refund will be approved, but it's worth contacting JetBlue to explain your situation.

No-Show Policy
If you fail to cancel your flight before departure, you forfeit all money associated with the ticket, including any ancillary purchases like checked baggage fees or seat upgrades.

In summary, whether you receive a refund when canceling a JetBlue flight depends on your ticket type and when you cancel. Refundable fares offer the most flexibility, while non-refundable fares may result in cancellation fees or travel credits. Always review your fare rules and consider purchasing refundable tickets if your travel plans are subject to change.
