This thread is really risking going off topic but I'm actually wondering what I should do. I'm at least temporarily based on Beijing now, but will fly to Toronto at least every 2 months or so. I've just about requalified for SE 2009 () and I'm wondering if I should be crediting elsewhere. Lately I've been using RTW fares in C. The threshold gifts are nice and all, but I would rather have upgrades and better treatment on other airlines. I've noticed that many of the other Star airlines just don't give a crap about *G, paid C passengers from other airlines. Not nice. Considering that I have between 150k and 300k of travel to credit elsewhere, which ones will get me better treatment (ie: concierge, priority waitlist, etc), and upgrades? In particular I'm thinking about UA (for E+? I only fly them one route internationally and it's in F anyway), SQ, NH, LH. Which of those are most complementary to AC status?
