I have been through this Airport @ least 100 times now. You seem to learn a little more every time you go through.
Today when we landed it was bright and sunny outside. But, then looking out the window there was snow every where.
This airport is huge and you can get a flight just about any where from here.
They have free Wi FI for starters, which is always good.
It is a really beautiful airport and the smell of southern BBQ is all through out. Shuttle and nice, not over whelming. Except when you go to the International side it seems sterile and clean, then as you keep going towards the gates it gets dark, like they dim the lights.
There are a lot of really good food choices at this airport , as well as some good shopping. It is set in a nice wooded area of NC.
As I write this I sit on a lovely white wood rocker, That was part of an Art Exhibit at one time. Now they are scattered through out for a lovely rest.
Real trees are growing in side with huge glass windows.
So as long as you give your self a lot of time for your flight you can look around and enjoy this Airport.
