This was not a routine flight delay. Because the pilots flew the night b before and were required to get sleep (which I appreciate), AA knew AT LEAST 8 hours before that they wouldn't;t be available to fly.
Not only did the send a text message that the flight was on time WAKING US AT 2 AM, they also failed to notify the crew.
There are lots of things that are out of their control, but this one was a big mistake to the crew, every one of the passengers. Even the agent when we checked in didn't;t know the flight was delayed.
