The thing is AMR has never done anything just to be nice and make friends with labor. It does what is in its best financial interest. If its interest is to park 50 airplanes it would have done it already,and without asking the pilots first if its ok. The is nothing stopping them from doing it. They have a plan which is secret and not in our best financial interest. They want us to sign off on a section 6 end-around, and then will probably unveil the plan for E175 outside flying, etc (just an example).
The entire reasoning we are given for approving the TA is: take this deal or else... It is a very classic tactic, but it doesnt make sense given the reasoning above. If it was cheaper to outsource the planes or park them, it would be done already. Don't buy in to the threat.
