What is the cancellation notice period for Singapore Airlines? Singapore Airlines typically requires passengers to cancel their flights at least 24 hours before the scheduled departure. This timeframe ensures you have a better chance of getting a refund if your ticket is refundable. For non-refundable tickets, though, there may be little flexibility, and cancellation could result in losing the ticket value, except for the taxes. To know the exact cancellation terms, review your ticket type under the “Fare Conditions” section.
