It's actually a better value to use on AA - considering 67.5K to Asia in F equals out to about 80K Aeroplan, but the added bonus is no YQ and no change fees for dates. Contrast that 105K redeemed through Aeroplan and YQ on many decent carriers. So the 16% haircut still puts you out on top (I've even taken a 30% haircut through Esso and Avion and still found it a bargain - I've saved a ton on lack of change fees.)
