I was very unimpressed by Charlotte Douglas Airport. Returning from France, this was my port of re-rentry and customs/border control was quite fast. The airport cannot be held accountable for the personalities or lack thereof by individuals at Immigration.
What I did find lacking were boards showing me where I needed to go to get my connecting flight home. One would think as you exited the screening process, there would be flight information boards but one would be wrong. I went to the C gates before I found a set of boards and realized I had to retrace my steps and go back.
The wait wasn't long but it was frustrating that you have free wifi but it's only good for 45 minutes. Then you lose it and have to sign back in. This is absurd! Just give people free wifi.
I couldn't help but think I was at a backwater airport. I almost gave it a 2 star review but since I did find my way with the help of an airport employee, I give it the 3.
