Please don't make this thread become Yankees vs. Texans.
I personally prefer Houston to AA's DFW/ORD and DL's ATL. IT's not too big. There is no need to wait 5 minutes for rail train. You can walk to your connection gate less than 15 minutes in most cases. The PC are decent, althought I think EWR's are better.
Houston is not a pit. It's a shame people saying that without really knowing the city.
