This airport is one of the worst I've ever been to, in terms of layout. The only positive thing is that there are so many entry points into the four (FOUR) different terminals that the wait to get through TSA is decently short.
Did I mention that the four terminals are not connected in any way? Means that, if you have a connecting flight with a different airline, be sure you have at least two hours between flights so you can get from terminal to terminal.
