Good luck with the Charlotte airport. I am not fond of that air port. Used to live outside of Charlotte and my husband flew several times for work and my sister flew a couple of times to visit us. Most of the it was more an issue with finding luggage upon getting off the plane because they never seem to know which luggage carousel is going to get what plane's luggage. The last I'd heard that is one of the air ports looking at kicking TSA out in favor of private security due to some issues.
