My guess is that Mike Isom is responding to those of us who wrote him complaining about the recent onslaught of fast track promos. He likely wants to put a lid on the folks who flew the "stated" miles or segments from finding out that you really only need to wait until near the end of the year and fly just a fraction on the "stated" miles or segments.
In my opinion, US Airways wants to have their cake and eat it too. They want one group to be loyal and follow the original rules and they want to give the same rewards to a second group who are far less loyal. I wonder if my wife will let me cheat on her the last three months of every year even though the rules at the beginning of the relationship were that we had to be faithful all year long? I wonder if Mike's wife would be ok with such an arrangement?
