Charlotte airport is a lovely layover stop
Charlotte CLT airport is a gem. Each time I travel through here I can't help but to relax.
Placed throughout the airport are white rocking chairs. One can pilot one of these babies and surely relax. Within range is free Wifi and a power outlet. If you are interested in speed and it's busy in the atrium, then I recommend going into one of the wings for unsaturated wifi areas.
A local American company makes the chairs. A rocking chair is definitely on my list of gadgets needed for the home. But for now, I will have Charlotte.
If you have a choice of layover airports, choose Charlotte. And give yourself a couple hours in-between your flights! Set your alarm in case you relax TOO much.
