I don't usually fly out of charlotte. I'm a slave to southwest at Raleigh, but southwest now has a very small amount of flights out of Charlotte so that may change.
Right now there is construction surrounding and inside the airport. If you are doing long term parking give yourself an extra 30 minutes of what you think you need. It took me more than 10 minutes to even find a parking space! Thankfully I got there earlier than expected and it saved me from missing my flight.
The construction on the inside is at baggage claim and many of the conveyor belts are out of service. This means airlines have to share one belt and it was a clusterfrack. The plus is they had way more than normal baggage attendants and everyone seemed to be getting attended to.
I'll use Charlotte again, I go where the best price and route times are so I'll be back. Soon I hope traveling to the clear blue sea.
