Ticket validity is typically one year: * Unused tickets: From the ticket issue date. * Partially used tickets: From the departure date of the first flight segment. Atlas system automatically validates the applicable deadline when a refund request is submitted. {% hint style="warning" %} Note: Refund requests submitted after the applicable deadline cannot be accepted. To avoid missing the deadline, submit your request as early as possible. {% endhint %} #### Voluntary and Involuntary Refunds You may refer to the table below to quickly identify the submission deadline for voluntary and involuntary refund requests across different airlines. **Important Notes:** * The Submission Deadline displayed on this page represents the default time limit configured in the Atlas system. The actual refund acceptance time limit may vary depending on the airline’s policy, whether the refund is voluntary or involuntary, the fare type, and other applicable factors. The airline’s rules and regulations in effect at the time the refund request is submitted will prevail. * In the “Time Value” column, a minus sign (–) indicates that the refund request must be submitted before the corresponding time point, while the absence of a minus sign indicates submission after the corresponding time point. * For example, “VJ: –1 day” means the request can be submitted up to one day before travel.
