I hope CO doesn't try something like this, if it means that the Silver Elite benefits will be devalued and new benefits will be limited to Gold and above, like what's happened with DL.

I've been motivated to do the opposite in part because of those changes, as I just hit Silver requalifiation on DL last week, and have moved most of my travel for the rest of the year over to CO and A* to requalify here as well.

I do think that rollover on it's own is a good thing, but wish FF status was more about BIS miles and less about CC bonuses.
