I made easy over 4 million (bonus, not status) miles with LX (swiss) Travelclub (that became now part of LH's miles&more program), profiting from last years promotion of a swiss Supermarket chain (Coop Switzerland), that did let points from that chain exchange 1:1 into swiss miles. It took me only 2 months to do so (profiting from extra bonus points from the chain, and trading points on auction platforms like ebay® and Ricardo©).
So I started at age 62 and finished with over 4 Million miles at age 63 ...
I will be (talking status now) a life long LH (miles&more) Senator (Star-Gold-level) on march-3-2008 (age 65, I did start with miles&more in 1998 at age 55). To become a LH life long Senator you don't need 1 Million status miles, but: > 60 years old, must be a current Senator, and must have been a Senator for the last 10 years (to qualify as a Senator you only have to make 100'000 status miles every second year, as status is valid 2 calendar years - so if you start at age 50 and do 100'000 status miles every second year, you become a lifelong Senator at age 60 with 'just' 500'000 status miles.
