If you are considering whether to cancel your WestJet flight and are after the refund, this will be very useful to understand the westjet airlines cancellation policy. WestJet is a company which offers flexibility to travelers but only in some specific conditions. The exact information is based on the fare type and your flight canceling time. Normally, assuming that you drop a trip in no less than 24 hours of procurement, you could be qualified for a full discount, given that the booking was made something like multi week ahead of time from the real flight date.
