I think the USAir/AA is basically like a musical chairs game. The last two are getting together, and they don't have much of a choice. I think it could be worse, but I don't think the networks blend together as well as DAL/NW and UAL/CAL. But lets see what kind of merger they can pull off. DAL/NW set the bar pretty high. UAL/CAL hasn't been able to reach it.
