Singapore Airlines provides refunds depending on the type of ticket purchased and the timing of the cancellation. Refundable tickets allow passengers to get back the full fare minus applicable fees, while non-refundable tickets may be eligible for a refund of taxes or surcharges. The 24-hour cancellation policy also applies for bookings made directly through the airline. Check your booking details for specific terms. For more information, review your fare conditions or visit the Singapore Airlines website to request a refund.
