After talking to an AA employee about the merger today, they said people are happy and the flight attendants are happy to be getting some more time off (apparently they are reducing the number of FAs on AA flights). Asked a flight attendant about that and they confirmed some people have a lot of time off next month and they went into how great it is that AA leadership is fired.
I didn't have the heart to tell them that the fact they're going to have a lot of people sitting around probably means they are going to have a large amount of "restructuring" (layoffs) in the near future. They made their bed, I guess they can lie in it.
I did have one of the best FAs ever on my flight though. Never taken this flight before or had him - so I'm not sure whether it can be attributed to him being a great employee or happy about the state of things and just giving great service.
