I once booked an Air Canada flight and realized almost immediately that I’d chosen the wrong date. I remembered hearing about their 24-hour free cancellation policy, but I wanted to be sure. I called 877-764-3622, and the rep confirmed that if it’s within 24 hours of booking and the flight is at least a week away, you can cancel or change your ticket without paying any fees. They helped me cancel and rebook the correct date in just a few minutes. Honestly, having someone walk me through it made me feel a lot more confident than trying to navigate it online. If you’re in the same situation, that number is the fastest way to handle cancellations and make changes stress-free.
