"After Sept 11th the union ensured that it was (LIFO) last In first out "
Oh really, I can think of a few A320 drivers with 2yrs plus in the company after 9/11 who might just take issue with you on that. The union rolled over and let them do it and only later on tried to make amends with respect to the same poor sods coming back. If they want to cut jobs by fleet they will, and there is sod all you or anyone else can or will do about it, especially since LIFO is now pretty much illegal under EU law.
Its a rotten bloody state of affairs and having been there myself I can only offer heartfelt sympathy and hope it doesn't happen again.
Best of luck to all concerned.
