Not sure this is the correct forum, mods please relocate if need be.

I'm wanting to find out which airline to switch to. I currently fly United, hovering between PremExec and 1k but all this done CONUS. I'm relocating to Tokyo and will be flying back and forth from the U.S. and also around Asia. Anyone have any suggestions on the Airline I should switch to? I'm not too impressed with United anymore (when was I?) so any excuse I can use. I guess it would be nice to keep it in the Star Alliance group but at this point I don't really care.

Thanks!
