A decent airport that features free wifi, limited shopping, and average TSA employees. The lines are seldom long and their retired people in Purple that go out of their way to help you out. They are building a sky train which will make transportation between terminals easier. I would give this airport a 3 but free wifi makes me have to give it a 4 :)
*insider tip: terminal 4 has showers in the bathrooms by the baggage claim
