I just got back home from Dallas. There was some confusion at the airport, and I can safely say I will never fly with American Airlines again. Here is an example of just how off things were today- this is an email update from Orbitz:
American Airlines flight 2046 is delayed. Departure from Dallas/Fort
Worth International (DFW) is now estimated at 10:45PM Gate A20.
Estimated arrival at Kansas City International (MCI) is now 10:40PM
