During the height of COVID, I had to cancel my Air Canada flight due to a medical issue and wasn’t sure what the rules were. I called 877-764-3622, and the representative explained that for COVID-related or medical cancellations, Air Canada often allows flexible rebooking or provides travel credit, sometimes waiving usual fees. They helped me cancel my booking and ensured I received credit for a future flight. Honestly, trying to navigate this online would have been stressful and confusing, but speaking with someone directly made it straightforward. If you need to cancel a flight due to COVID or a medical reason, calling that number is the fastest way to understand your options and handle the situation efficiently without worry.
