WestJet allows passengers to cancel a flight within 24 hours of booking for a full refund if the booking is made at least seven days before departure. Refundable fares like Premium Flex and Business Flex can be canceled anytime before departure for a full refund to the original payment method. Non-refundable fares such as Basic, Econo, and Member Exclusive are not eligible for refunds after 24 hours but may receive travel credits in some cases. Cancellation fees depend on fare type and destination. Econo and Member Exclusive fares have cancellation fees between $100 and $118 CAD for domestic and most international flights, and $250 to $295 CAD for flights to or from Europe. Premium fares have similar fees. Business fares have higher cancellation fees, ranging from $600 to $708 CAD for Europe-bound flights. Econo Flex fares can be canceled without a fee for domestic flights, but cancellation fees apply to other routes depending on timing. Passengers can cancel flights online through the Manage Trips section by providing their booking details. Cancellations through travel agencies must be handled directly with the agency. Refunds are processed to the original payment method and may take several days or weeks. If WestJet cancels a flight, passengers are eligible for a full refund or rebooking without extra cost. Compensation may be offered for delays or cancellations depending on the situation. Travelers should check fare rules when booking to understand their cancellation rights and fees.
