Very small and convenient airport that fly between Concord/Charlotte to mostly Florida locations. I personally haven't flown in or out but I've been several times to take my teenager and pick her up and the same for my mother and siblings. I've been in to wait with them, I've even parked at the parking deck.
I've had nothing but good experiences with family and through discussions with family they didn't have any issues either except one earlier this year however after sending an email to allegiant it was resolved sorta which is why I'm at a HARD 3 1/2 Stars.
The airport is easy to find and just to be clear you board the plane from outside so dress accordingly.
