Singapore Airlines has a cancellation policy that depends on the type of ticket purchased and when the cancellation is made. For flights to or from the United States, passengers can cancel their booking within 24 hours of purchase without penalty if the booking was made at least seven days before departure. This applies to all fare types. Refundable tickets offer the most flexibility and can be canceled at any time before departure for a full refund to the original payment method. Non-refundable tickets can be canceled but are subject to cancellation fees that vary depending on the fare class and route. After deducting the fee, the remaining value is issued as travel credit valid for one year from the original ticket issue date. Award tickets booked with KrisFlyer miles can be canceled before departure, with miles redeposited into the passenger’s account, usually for a fee unless the airline cancels the flight, in which case fees may be waived. In exceptional situations like death of a passenger or military or jury duty, cancellation fees may be waived with proper documentation. To cancel a flight, passengers can use the Singapore Airlines website by accessing “Manage Booking,” the mobile app, call customer service, or visit a ticket counter. Overall, Singapore Airlines offers flexibility with refundable tickets allowing full refunds and non-refundable tickets providing travel credits after fees. The 24-hour risk-free cancellation window applies for flights involving the United States, helping travelers avoid fees if plans change shortly after booking. Award ticket cancellations are possible with mile redeposit, usually for a fee. Understanding these policies helps passengers plan and manage their bookings with confidence. Singapore Airlines balances fare rules and customer needs by offering options for cancellations and refunds based on ticket type and timing. This policy allows travelers to make changes with clear information about fees and credits, ensuring a fair process for different fare classes.
