KOI,
I hope LIFO is employed in MYT otherwise a seniority list is worthless. BALPA has made mistakes over the years but has learnt from it. Some guys will take the shafting BA administered to them in conjunction with BALPA to the grave with them and that is understandable. BALPA suffered considerably as a consequence of the Dan Air fiasco.
You seem conveniently to omit the attempt by Virgin management to axe 747 pilots irrespective of seniority post 9/11. BALPA isn't perfect but without it you are at the mercy of management who would make cutbacks in the cheapest fashion possible.
