American decided to cancel our flight from Miami to San francisco. Various alternatives were discussed and discarded on the grounds that it takes more than ten minutes to get to Miami from Fort Lauderdale and routing via South Caroline would have given us another state to tick off but taken rather longer. So here we are back at Dallas thanks to the herioic efforts of the pr, the conference organiser, the travel agent, the driver and the checkin guy at the airport. No points to anyone else at American, from the ticketing agent who gave the travel agent the runaround to the checkin helper who told me to get in line behind everyone else with ticket problems when we had less than 45 minutes to catch the flight. We have a choice of bankrupt American airlines to fly and American is down the bottom of the list with America West for me now.
