The original story said she was disruptive on the outbound leg. She was allegedly erratic at check in. Other crew members tried to have her removed. The F/A supervisor refused, she was allowed to remain on the flight. Weak Captain, weak crew members for putting up with this. The company should be hit with a big fine for this.
Charlotte is a very strange base. There are very senior people who should have retired years ago, they are barely able to function in the job. F/A training, especially recurrent, is a joke. Minimal testing, everyone passes. Pilot training at that center is slightly better, but the whole culture is to train to the absolute minimum standards. The hull losses US Airways suffered before and after the AWA merger are testament to that.
Thankfully there is a new sheriff in town from Texas and I would expect to see more changes made in the former east bases and the CLT training center. Pilot managers have already been replaced in PHL and CLT is on the way.
