I haven't seen it, flights are still really full and changing a flight is a nightmare. I have a friend on a 2 day lay-over in Nashville because his flight was cancelled last night and the next available flight out for him is Monday morning. Though I think he is on SWA, which would explain why he cannot just get moved to another airline.
I think things are still pretty tight right now, especially this Summer with getting flights and seats.
