Copa Airlines, a South American Star Alliance airline, hasn’t been bookable on Aeroplan for a while. They’re a pretty good airline for award availability, and Aeroplan doesn’t charge fuel surcharges (YQ) on them. Aeroplan has been the only Star Alliance frequent flyer program that hasn’t been able to book Copa flights. Throughout the year, there have been short periods, in terms of hours, that Copa has been bookable. Right now, Copa is bookable. This could be a permanent fix to the issue, or could be short lasting.
If you’ve been looking at booking Copa using Aeroplan, or looking to go to South America on points, I’d suggest booking now!
