I pretty much never fly any Star Alliance airlines since there is basically no service into Key West, my home airport. I occasionally fly them intra-Europe and I have always credited anything like that to Aeroplan since I use Amex rewards to book award flights outside of Sky Team. I have a situation coming in a couple of months where I'm going to get some 10,000 miles on Austrian and Lufthansa. Given the questionable future for Aeroplan and my use of Amex for rewards, any suggestions where those miles would best be put to use?
