I was stuck in the same situation around the same time as the previous commenter. I waited in DFW airport for almost 3 days waiting for a flight out due to fog which was a legitimate problem. However my biggest complaint was the seeming nonchalance about the situation. After being put on standby after my initial flight was cancelled and watching the next 4 flights cancel as well I was informed that no more flights were going out that day (it was 7pm) and no more would be scheduled. Granted I don't know the specifics that need to take place to schedule/staff flights but I don't feel like AE/AA did anywhere near what they could have to remedy the situation. On another trip I arrived to the small regional airport I fly out of 40 minutes before my flight (I know they say an hour but its such a tiny place there is never an issue). I went to the check in desk and found that there were no AE/AA employees there. Anywhere. I asked the agent from another line what was going on and was told "AE runs with only barebones staff and he went on break." I waited 15 minutes until the agent arrived and was told "Oh ma'am you missed your flight." I then spent the rest of the day on standby trying to catch one of only a few flights out. I made it thank goodness but the nonchalance and general organization of AE definitely made for a less than pleasant trip.
