Charlotte is usually my layover in transit when I cannot have a straight flight. With that being said I'm going from the gate and I do not have the full TSA, parking or any of the extras worries.
The airport is very clean compared to the others I've been to, the food vendors are decent but lack on healthy eating spots (I try to eat well since I'm about to sit on a plane) and most importantly, the gates are labelled well if I'm in a rush. Did I mention that I love the Southern charm? Well, that's just the nice part of visiting the Southerners.
