I've been crediting all of my miles this year to M&M - which is galling because I'm over 55k so losing all of the bonus miles, but I have no use for miles if they are going to be moved to BA.

As Flying Blue have just announced that they will roll over miles, my plan will be to qualify Senator this year, then qualify FB Plat next year, and roll enough miles over to 2014 to qualify for 2015 too. Then in 2014 I'll requalify for SEN, and so on. This is of course assuming both FB and M&M stay the same, which is very unlikely.

I'm not relishing going back to AF/KLM as I jumped ship from them to DC a few years ago when they changed the program around. Having looked at all of the *A options though, with DC about to go there is nothing that is much better than Flying Blue.
