Well, everyone is basically getting a raise (except for Eagle) and, with the exception of retirees, everyone is getting much better non-rev travel opportunities. This makes for happy employees. Happy employees = happy customers. It's not rocket science (though, if you've flown UA lately, you might be lead to believe otherwise).
So, the new AA management team is smart when it comes to employees thus far. Let's see if they're smart when it comes to frequent fliers. I'm cautiously optimistic, given what we've seen so far. But, we've seen very little.
