Star Alliance mileage inconsistencies
I am an Aeroplan member with Air Canada but travel frequently in Europe on Star Alliance partners, primarily Lufthansa. I notice I am only credited with 50% of miles travelled to my Aeroplan account when I fly Lufthansa. When I fly SAS (also Star Alliance) I receive full mileage. Does anyone have an explanation for this? These are all flights more than 500 miles in length taken in ecomony.
