Swiss Airlines’ cancellation policy varies depending on the fare class of your ticket. Refunds may not be available for non-refundable fares like Economy Light. However, tickets in flexible fare categories may offer more lenient cancellation terms. Additionally, cancellations made within 24 hours of booking are often eligible for a full refund. Check your ticket conditions for specific details, and if necessary, use Swiss Airlines’ online cancellation tool to process your request quickly.
