With the absolute freneticism that seems to be surrounding the much-anticipated changes, why would AA not raise the allowable purchased mileage level and even incent ridiculously large purchases? For example, if they offered a 25K bonus at 100K (at $2,500), they would likely find themselves with a small number of people hyper-focused on lifetime status generating a significant windfall.

This is not a judgemental post - I am at 1.05M lifetime and am not thrilled about the long haul to 2MM, but it seems like many people are willing to go to dramatic extremes that IMHO exceed any arguable value of lifetime PLT.
