I had booked a multi-leg Air Canada trip for my family, and last minute, one of us couldn’t travel. I wasn’t sure if I could cancel just one leg or one passenger without affecting the rest of the booking. I called 877-764-3622, and the agent explained the options clearly. For regular tickets, you can sometimes cancel a single leg or passenger, though fees may apply, and for award bookings, the process is slightly different but still manageable. They helped me cancel just my son’s ticket and ensured that the rest of our booking remained intact. The points from his award ticket were returned without any hassle. Honestly, doing this online would have been confusing, but the call made it simple. If you ever need to modify part of a booking, calling that number is the fastest and safest way to handle it.
