As you know, as a Delta Platinum Medallion Elite Plus, I have been extremely angered by their changes to a 'how much you pay' program. Well, now United has joined the group:
Others have already done so, which leaves American. I have little doubt they will follow suit unless people who actually do fly a huge amount of miles and pay large amounts of money desert (like I plan to). I am planning to keep my Platinum Elite Plus this year so that it will follow me next year, but then it's off to the best deal I can get. And Amex can also bite the dust next year as far as I am concerned.
