Briefly, In Charlotte

If you are flying to the eastern seaboard of the United 
States, there are far worse airports to have to sit out a long 
layover in than Charlotte, North Carolina's. Charlotte's fairly new airport consists of five boarding/disembarking terminals that, when viewed from the air resemble one of those Nazca desert drawings of animals. All five terminals have plenty of places to grab a quick bite or drink, and the main terminal has a few larger restaurants and lounges to while away the time between flights. That being said it bears mentioning that if your layover is very short, and your initial flight deplanes at a gate in the C terminal, and your connecting flight departs from a gate in the B terminal, with maybe a 20, 25 min window for you to heel-toe express it to the aforementioned departure gate...well, you're kidding yourself if you think you have time to pop on by the Stock Car Cafe for a quick drink. Seriously, don't do it. Gate C 19 is much further from gate B 13 than it looks on that map of the airport. Especially if you have hordes of fellow travelers to wade through.
