Our flight out of CLT was originally at 9:35, which gave us over an hour to connect; now it's at 9:05. The 9:35 flight is still showing, but I'll bet one or the other of those flights gets canceled. I just don't see AA operating two non-stops thirty minutes apart. My biggest fear is missing that connection, which would render our tests out of date, and we'd have to start over. Either that, or getting put on a later flight the same day, losing our first class seats, and being stuck in middle seats in the back of the plane. I'm trying not to stress over it, but our experience over the past couple of years hasn't been that great.
