Singapore Airlines' cancellation policy depends on several factors, including the type of fare purchased, how the booking was made, and the circumstances around the cancellation. If you purchase a ticket directly from Singapore Airlines and cancel within 24 hours of booking, and the departure is at least seven days away, you are eligible for a full refund with no penalty under their 24-hour risk-free cancellation policy. This applies regardless of whether your fare is refundable or non-refundable. For refundable fares, you can cancel your booking at any time before the flight's departure and receive a full refund to your original payment method. In some cases, a small processing or administrative fee may be charged, depending on the fare rules. For non-refundable fares, the main portion of the fare is not refunded if you choose to cancel, but government-imposed taxes and certain fees are usually refundable. If your flight is cancelled by Singapore Airlines or significantly rescheduled, you are entitled to a full refund, even if your ticket was non-refundable. If you used KrisFlyer miles to book your flight, cancellations are allowed, but there may be a miles redeposit fee depending on the type of award ticket. For Saver awards, the fee is typically higher, while Advantage awards may have a lower fee. However, if the cancellation is initiated by the airline, these fees are usually waived. When cancelling due to a personal emergency, such as a serious illness or the death of a close family member, Singapore Airlines may consider waiving cancellation fees for non-refundable tickets if you provide valid documentation. Refunds are generally processed within a few weeks, though the exact timing can vary depending on your payment method or bank. If you booked your ticket through a travel agency or an online travel website, Singapore Airlines will not process the refund directly, and you will need to contact the third party to handle the cancellation and any refund requests. The flexibility of your cancellation options also depends on your fare class. Economy Lite fares are the most restrictive and often do not allow cancellations or changes. Economy Value and Standard fares may be cancelled for a fee, and Premium Economy or Business Flexi fares generally allow greater flexibility with smaller or no fees. If you fail to cancel your flight before departure and do not show up at the airport, a no-show penalty may apply, and you may lose the full value of the ticket. Passengers are encouraged to review fare conditions carefully when booking, so they understand the rules regarding changes and cancellations. Cancellations can be made through the airline's website or app if the booking was made directly. Singapore Airlines aims to provide fair and clear options for passengers who need to cancel their flights, while also maintaining policies that match different fare types. Being aware of your ticket’s conditions can help avoid unexpected costs and make it easier to manage your travel plans if they change.
