My mom was flying on AA to Vegas today from Dallas! So far they are 4 hours late and no one will tell them anything. They have boarded the plane twice and have been taken off twice due to parts breaking on the airplane. Her flight prior was 2 hrs late . AA has got major problems!
If you want to work in this industry, then you have to learn that these things can happen from time to time, and to any company. A single maintenance delay is by no means indicative of "major problems."
AA has been have a high number of cancellations due to sick calls and maintenance issues. It isn't unreasonable to believe that it is related to the recent events in their bankruptcy hearings and not a random circumstance.
