My flight to Chattanooga was cancelled due to bad weather in Chicago. They had rescheduled me for tomorrow on a 6 am flight, which would have put me back too late to be on the panel at Chattacon. I explained my dilemma, and American rerouted me onto a Continental flight to Atlanta. I’ll have to take a shuttle up to Chattanooga, but will still get in about the same time.
So, really, this is pretty mild as travel karma goes. If it were in full swing, then I would have gotten stuck in Chicago.
