Based in SFO, and looking to earn 5000+ miles on LH M&M to Europe (or S. America) over the Labor day weekend. Ideally returning to US on Sep 4 or 5. Alternatively, flying over any weekend in Sep/Oct. Any suggestions? Flights in coach, fares do not need to be upgradeable. Could fly as far east as Russia or Kazhakstan (in fact, would love to travel to the former USSR). Any suggestions welcome, I'm not finding very good fares at the moment).
