I actually had to change my Air Canada booking a few months ago when work meetings shifted. At first, I tried doing it through the website, but honestly it was a bit confusing with all the different fare options and fees. I didn’t want to risk messing it up, so I called 877-764-3622 instead. The rep was super patient—walked me through my choices, explained the price difference, and rebooked me on a later flight the same day. It only took about 15 minutes, and I felt way less stressed than trying to figure it out myself. If you’re short on time or just want it done right, that number is hands down the easiest way to handle changes.
