Yes, you can cancel a Qatar Airways ticket, but eligibility for a refund depends on the Qatar Airways refund policy. Refunds are generally available for tickets canceled within 24 hours of booking. Afterward, cancellation fees may apply based on fare conditions. Refunds for non-refundable tickets are limited. Passengers can request refunds online through the "Manage Booking" section or contact customer service for assistance. Travel vouchers may also be offered instead of refunds.
