Qatar Airways has a 24-hour cancellation window where passengers can cancel their booking for free, as long as the flight departs at least seven days later. During this period, travelers can secure a full refund with no penalties. If you need to cancel outside this 24-hour window, the conditions depend on your fare type. Refundable tickets offer greater flexibility and often allow cancellations with minimal fees, while non-refundable tickets have stricter terms.
