This isn't necessarily for the Charlotte hub but for Delta as a whole. They have posters everywhere stating building a better airline not a bigger airline. Based on my experiences the last four weeks I am now convinced these are a misprint. As a consistent platinum or diamond traveller (100k+) annually, I fly Delta as they are the best of the worse. However, somebody needs to tell Richard Anderson, the CEO, that he isn't building a better airline. He's building a worse airline. The last four weeks I've experienced mechanical issues on just about every flight, numerous cancelled flights and rude customer service agents, particularly at the Atlanta hub. Don't even get me started on baggage handling. I've now joined the masses in doing carry on because of the inept delta baggage handling. Not sure what is happening at Delta but it is definitely going in the wrong direction.
