The Air Canada Cancellation Policy is designed to provide travelers with flexibility and clarity. Passengers can cancel any booking within 24 hours of purchase for a full refund, as long as the flight departs at least seven days later. After this period, the rules depend on the ticket type. Basic Economy fares are usually non-refundable, while Standard, Flex, Premium Economy, and Business fares may allow cancellations with fees or travel credits. Refundable fares offer the most freedom, giving travelers cash refunds to the original payment method. Checking your ticket conditions ensures smooth changes without unexpected expenses.
