If you need to cancel your flight, the Singapore Airlines Zurich Office can guide you through the process. They will explain how to cancel your booking and inform you about any potential refunds. If your ticket is refundable, they will help you request a refund and explain how long it might take. In some cases, you may receive a travel voucher instead of a cash refund, which can be used for future flights. The staff will ensure you understand all your options and make the cancellation process as easy as possible.
