You would really need to examine the earnings on each program for your Economy Class flying, and then consider the redemption rates for your Economy Class award trips.
Thank you so much! I have to admit I was hoping that is the kind of analysis that someone already might have done, at least as a rule of thumb. For instance, once upon a time the theory was that TK was the best choice because it has very cheap redemption rates (which is still often true, but their availability and customer service leave me wanting).
