Z class, air canada? Is there a page on aeroplan that helps you calculate?
Knowing that it is Z class helps as we now know that you'll receive 50% COS on domestic (if any) and 25% COS on int'l segments.
You still need to provide more information as AC does not fly to your destination with it's own metal. In order to help you, please provide the followng:
1) What is your routing?
2) Which airline is operating each of your segments?
3) Are your non-AC segments code share with an AC flight number. If not, what is the fare basis for those segments?
There is no AE mileage calculator. Use the calculator above for the base mileage. For COS bonus, etc. look up the mileage accrual charts for the various partners on the AC site.
