AA is the only airline I'm managed to get thrown off an aircraft - for sitting in a seat and saying nothing (literally)
The ground crew were fine and apologized, but lodging a complaint at their hub (Fort Worth) resulted in eventually getting a contrived letter (avoiding any liability) and referring to the "unfortunate incident on the flight to Johannesburg". The only problem was I was never on any flight to Johannesburg. Clueless
Then there was the AA aircraft with a crack in the flight deck windows which they wanted to fly, but was grounded - fortunately....
Then there was the AA aircraft with the navigation lights not working, - again, fortunately grounded...
Shit.. AA are worse than AeroFlot before they were dismantled...
