Singapore Airlines has a clear cancellation policy that depends on the type of ticket purchased and how it was booked. For tickets booked directly with the airline, passengers traveling to or from the United States can cancel within 24 hours of purchase for a full refund if the flight is at least seven days away. Outside of this window, cancellation fees apply based on fare type. Lite fares are generally non-refundable, with only unused airport taxes refundable. Value and Standard fares are refundable with a cancellation fee that may range from around $100 to $200. Flexi fares offer more flexibility and lower cancellation fees, usually around $50 to $100. Premium cabins such as Business Class and First Class may also incur cancellation fees depending on the fare conditions. For KrisFlyer award bookings, cancellation fees apply as well, typically $75 for Saver awards and $50 for Advantage awards. Refunds are made to the original payment method. Refunds for credit card purchases usually take about seven business days, while those for cash or check may take longer. If a passenger does not show up for the flight, a no-show fee is charged, which varies by class of service. Economy no-show fees are typically around $100, and for Premium Economy, Business, and First Class, the fees can be higher, sometimes up to $300. Refunds for no-shows depend on fare rules and may not be available for some fare types. If the ticket was booked through a travel agency or third-party website, cancellations must be made through the original booking source, as Singapore Airlines is not able to process such cancellations directly. The airline encourages passengers to review the fare conditions at the time of booking to understand their refund and cancellation eligibility. Overall, the policy aims to provide flexibility while also maintaining structured rules for different fare types. Understanding the specific rules for your booking will help avoid unnecessary fees and ensure a smoother cancellation or refund process if needed.
