Singapore Airlines has a cancellation policy based on the timing of cancellation and the type of ticket purchased. If you cancel within 24 hours of booking and your flight departs at least seven days later, you will receive a full refund regardless of the fare type. After this period, cancellation rules depend on the fare class. Lite fares cannot be canceled or changed after booking, with only taxes refundable. Value and Standard fares allow cancellations with fees deducted from the refund. Flexi, Business, and First Class fares provide more flexibility with lower or no cancellation fees. If the airline cancels the flight or makes a significant schedule change, passengers are entitled to a full refund or free rebooking no matter the fare. Award tickets can be canceled with a redeposit fee, which is waived if the airline cancels the flight. Refunds usually take between 7 and 21 days to process, depending on the payment method. To cancel or request a refund, passengers can use the Manage Booking section on the Singapore Airlines website or contact customer service. Tickets booked through travel agents must be canceled through the agent. Partial cancellations are generally not allowed online; the entire itinerary must be canceled. Cancellation fees vary by fare type and route. Overall, Singapore Airlines offers a 24-hour risk-free cancellation period, full refunds for airline cancellations, and flexible options for higher fare classes while basic economy fares have stricter cancellation limits.
