The reality is most regular AM users pay attention and had this all figured out. Really all this reversal has done is put in place the devaluing of points for all users down the road. So thanks. Regardless, the same end result will happen. Airmiles will get millions of points that were never going to be redeemed off their books. 

BTW the "issue" of people seeing different things online for redemption is actually the same as other websites that use  dynamic pricing or targeted offers. Its amazing how many people dont know that.
