Came into CLT yesterday at 5:15 PM. I arrived into B5 and I had 35 minutes until my next flight boarded so I decided to brave the B Club
I waited in a line of a few people. The agent at the front door had a counter of how many people were in the lounge and she did a great job tracking how many people were coming and going. Once I got in I found a table by the bar and sat there for a half hour. It wasn't too bad.
