Qatar Airways does not have a universal free cancellation policy for all tickets. However, they offer a 24-hour cancellation window and certain fare types that allow free cancellations under specific conditions.

Qatar Airways' 24-hour cancellation policy enables passengers to cancel their flight and receive a full refund if the cancellation occurs within 24 hours of booking and the scheduled departure is at least seven days away. This policy applies to all ticket types, including refundable and non-refundable fares, provided the booking was made directly through Qatar Airways. However, this policy does not apply to tickets purchased using Future Travel Credits, eGift vouchers, or frequent flyer miles.

Additionally, certain fare types, such as Economy Comfort, Business Elite, and First Class, offer free cancellation. Passengers holding these tickets can cancel their flight without incurring any cancellation fees. In contrast, other fare types may impose cancellation fees or offer non-refundable tickets.(winktraveldeals.com)

In exceptional circumstances, such as the death of an immediate family member, passengers may request a free cancellation. To process such requests, appropriate documentation, such as a death certificate, is required.(airlinespolicy.com)

If Qatar Airways cancels a flight, passengers are entitled to a full refund or the option to rebook without additional charges. In some cases, passengers may also be eligible for compensation, depending on the specific circumstances and applicable regulations.

In summary, while Qatar Airways does not have a blanket free cancellation policy, they provide a 24-hour cancellation window and certain fare types that allow free cancellations under specific conditions. It's advisable to review the terms and conditions associated with your ticket and contact Qatar Airways' customer service for guidance tailored to your situation.
