Air Canada is now officially participating in the Star Alliance Upgrade Awards program which allows members from Aeroplan and other Star Alliance programs to use their miles to upgrade on eligible Air Canada and Jazz Flights. The upgrades only work on Latitude fares (Economy Y or B booking class) and can be requested right as soon as your booking is confirmed. See Aeroplan’s Star Alliance Upgrade Page for more details.
For Aeroplan members, you can now use your miles to also upgrade on participating Star Alliance partner flights starting from as little as 7,500 Aeroplan miles. See the Star Alliance Upgrade Award Chart for more details
