CLT is top of my list of airports I have gone through in terms of friendliness. I am referring to airport workers and TSA. Other reviewers have commented about airlines and I don't think those comments should be directed to the airport. When I say friendliness, I mean from entering the airport to going through security. No rude or overzealous TSA like you see at OAK, SFO, PHX, OGG (yes, Maui!).
