Kremin,
Before you accuse others of incorrect statements I will spell out a FACT for you. In around 2001 a QF company which was being closed down sought assistance to redeploy it's staff(pilots). Mainline(management) indicated that the greatest hurdle in this was AIPA,FACT!
Industrial issues sit on both sides, don't think it is management. Feel free to message me and I will enlighten you with numerous details of some key players within the QF management who indicated this.
