This question may have been asked before, but I was just wondering as most surveys relate to Business/First Class, which is sortof irrelevant for me.

American has some more room, but aside from that, is there any difference between the airlines? Are any of them truly "better" or "worse"? In my experience, they all seem about the same - food varies, fa's can be charming or surly, etc...

I'm about to use up all my miles on both AA and UA, so I'm thinking about where to focus in the future. BTW, I live in L.A.

Thanks
