 For American, United, and Delta, more than 50 flights already canceled in Charlotte. Mary Calkins is out at the airport where the lines are long. We've reported at the airport so many times that I can tell you I don't think I've ever seen anything like this. This communication outage, it impacts flights from United, from Delta, and American Airlines. That, regardless of where they depart or where that plane is headed to, that is a nationwide ground stop for those airlines. Now, we've seen long lines, of course, a lot of confusion, people going to help desks, asking for more information.
