Welcome to FT!
As with many I took the changes to DM seriously and altered my flying pattern to be "less loyal." As a result I will not be CP next year (with luck and the reinstatement of the 500 mile minimum I will make it to Gold.)
It's nice to have these changes - with some you'll find it's too little, too late, but for most of us it's a welcome change that may make a difference for our flying choices next year.
Now let's get US to start working on all those fees for preferred members to book or change rewards, etc.....
