Singapore Airlines has a cancellation policy that depends on when you cancel, where you’re flying, and the type of ticket you purchased. If you cancel within 24 hours of booking and your flight is at least seven days away, you can get a full refund regardless of the fare, including non-refundable tickets, especially for flights to or from the U.S. booked directly with the airline. After this 24-hour period, the refund options change based on the fare class. Lite fares, which are the most basic economy tickets, usually cannot be canceled or changed and only taxes may be refunded. Value and Standard economy fares allow cancellations but may have cancellation fees deducted from the refund. Flexi fares and higher classes like Business and First offer more flexibility, allowing cancellations with little or no fee. If Singapore Airlines cancels your flight or makes a significant schedule change, you are entitled to a full refund or free rebooking, no matter the fare you bought. KrisFlyer award tickets can be canceled and miles redeposited, but a fee may apply unless the cancellation is made by the airline. Refunds generally take about one to three weeks to process, depending on your bank or payment method. To cancel or request a refund, you should visit the “Manage Booking” section on the Singapore Airlines website or contact their customer service directly. Tickets booked through travel agents must be canceled through the agent. Partial cancellations of itineraries usually aren’t allowed online; you must cancel the entire booking and rebook the desired segments. Some passengers have reported confusion regarding the 24-hour refund rule for Lite fares but insisting on the airline’s published policy often resolves the issue. Cancellation fees vary by fare type and route, so it’s important to check your ticket’s terms before booking. Overall, Singapore Airlines offers a 24-hour risk-free cancellation window, full refunds for cancellations initiated by the airline, and flexible options for higher fare classes, while basic economy tickets come with stricter cancellation rules and fees.
