Peter42, while I'm with you that M&M is much more desireable for pax flying F or C, it even has its strenghts for people flying Y. You get almost always 1000 minimum miles, can upgrade on LH from any fare and the blackout dates for award flights are moderate. Now if they could lower the mileage requirements for FTL and SEN...
I calculated my miles for 2000 and LH M&M performed better for me than UA M+ although most FT'ers would recommend M+ for people flying Economy. But for me M&M is the better program. So, please, LH don't alter anything but the mileage requirements.
