B A Lert,
You do not know what you are talking about. Competitive Tender?
AIPA (mainline) had NO opportunity to even begin such a process. They were completely shut out of all J* negotiations, domestic and International. This was despite the considerable cooperation that the company and AIPA had enjoyed during the past.
Industrial muscle of AIPA? Now you are really kidding. There is none and never was any (since '69 or whenever). They have never been militant.
A win/win is exactly what AIPA wanted. Unfortunately the company does not subscribe to such a view, they prefer war/war.
