As a LH Miles&More FTL = Star Alliance Silver came back from US trip as first timer on a US Airways flight from Europe to Chicago via PHL and vice-versa, which I kinda like.
I mainly fly within Europe, but 3-4 times to the USA plus Asia, do you think it would make sense to change from Lufthansa's M&M to US Airways' Dividend Miles in order to gain Star Alliance GOLD status (US Airways = 50'000 miles/p.a., LH M&M = 100'000 miles/p.a.)?
Thx for clarification!
