Singapore Airlines has a clear cancellation policy based on the type of ticket purchased. For tickets booked to or from the United States, passengers can cancel within 24 hours of booking without any fee, as long as the departure is more than seven days away. After that period, the ability to cancel and receive a refund depends on the fare class. Non-refundable fares like Economy Lite generally do not allow cancellations for a refund, though passengers may still receive a refund of unused government taxes. For other fare types such as Economy Value, Economy Standard, Premium Economy, Business, and First Class, cancellations are usually allowed with a fee that varies based on the fare rules. These fees can range from about 50 to 200 US dollars. In the case of a no-show, when a passenger misses their flight without cancelling, the booking is treated as canceled with potential forfeiture of the fare depending on the ticket rules. For award tickets booked using KrisFlyer miles, cancellation fees also apply. Saver award tickets typically have a higher cancellation fee compared to Advantage award tickets. Any applicable service fees, such as those for offline cancellation, may be charged separately. Refunds are generally issued to the original payment method. If the ticket was paid for by credit card, refunds may take about seven business days, while refunds for cash or check payments can take up to 20 business days. Passengers who booked directly with Singapore Airlines can cancel their bookings through the airline’s website or customer service. Those who booked through a travel agent must contact the agent directly for changes or cancellations. Understanding your specific fare conditions is important before making any changes, as each fare class has different rules and fees.
