Well with Membership Rewards I can transfer points to several plans including Delta, Aeroplan, ANA, British Airways, Krisflyer, and Continental. It seemed like Aeroplan was usually the best way to go for ultimately flying on a StarAlliance flight although their recent plan changes somewhat devalued their miles.

To be honest I have only begun researching the taxes and surcharges, let alone figuring out how to check reward flight availability without actually having points in my account. ANA seemed to have some flights and Aeroplan seemed to offer a good number of options.
