I like how updated and clean this airport is compared to others. However, the attendants at the gate (at least for US Airways shuttle flights) can be annoyingly slow and meh, for lack of a better word.
Be cautious though, if you have a short connection time. Your travel from one gate to another can be verrrrry lengthy. I agree with Nicole S. - not sure why they put US Airways flights in different concourses, especially when a million of them connect in Charlotte...
