Just remember not to get caught out with any illegal job action. No doubt AA management will sue the union and individual members like others have done.
I still say a mass resignation is the way to go. Takes a lot of guts but it is not illegal. With no pilots they cannot run the airline. They weren't too happy when they had higher than expected retirements last year.
I know it will never happen but it would be amazing if any group ever had the balls to do it. It would be historic for any labor group.
