This airport can definitely be a bit confusing to get around at first, which is odd since it is not that big. After you figure out the layout is not a problem. The main problem with this airport is that there are too many flights. It is over capacity when any little thing goes wrong with schedules there can be big delays, since most of the gates are full. The number of people also make it very difficult to get transportation out of the airport - free shuttles fill up, taxi lines get long, the traffic can be bad.
The security lines were not very long compared to the lines to get checked in. It seems the TSA here is equipped to handle the people.
The "Orange Line" train runs right next to the airport. It is a pretty long walk, but the first 1/2 is all inside.
