I just asked a question in another thread, which prompted me to do a search and I found a few threads related, but no definitively titled one.

What do you guys find to be the best airports you frequent? How about the worst? What I mean is flight timeliness/reliability, connections, staff availability and friendliness, and overall experience?

I realize there are different classes of airports (comparing John Wayne to LAX is obviously not a fair comparison) but in general?

I am fortunate that my home base (DIA) is fairly reliable and generally have helpful staff. The fact that the land is huge and there are a lot of runways means not a lot of delays.

On the other hand, I have to connect through ORD quite often and I am almost always delayed, the staff seem much more rude in general, and I always feel a bit unhappier after having spent time there.
