Not too bad of a configuration. Some areas look like they've been renovated fairly recently. TSA Precheck line is at the far end of the one terminal, but not bad of a walk or anything. Some renovations still going on, but that is pretty consistent with any airport.
The airport rental car center was pretty nice, although minor design flaw is that for many of the car rental companies, there is a gap between their area and the terminal where you aren't under cover, so if it is raining, you might get a little wet.
