Changing your flight with Air Canada doesn’t have to be a stressful process if you’re familiar with their flight change policy. Depending on your ticket type, you may be able to make changes without incurring a fee, especially if you booked a flexible fare. However, basic fares generally come with higher fees for changes, and the cost of rebooking varies by destination. Air Canada provides multiple options for making changes, including online through their website or app, which is often the quickest and most convenient method.
