I've been flying into Charlotte for most of my adult life ..... Mostly because flying into Columbia is so god awful expensive. It's always been a pleasant experience with no real hiccups ever.
Current construction on the parking structure means parking further away and taking a shuttle.
The airport itself is cozy ( quite small ) but has everything one might need at the beginning of a travel day or at the end.
TONS of hotel options in the area.
A fair amount of food options throughout the terminal.
There IS a Starbucks.
The TSA process seems to be relatively organized ( that's saying something ).
The staff of the airport are actually very friendly, and this extends to the restaurant employees as well ( please refer to my Wendy's review ).
Too bad there isn't a non-stop from Honolulu ( there used to be with US Airways ), I would gladly pay a little more for that option.
Easy to get around. Signs are easy to read and navigate.
I'm sure I'll continue to frequent CLT unless something makes Columbia cheaper.
