One wonders why ST09 introduced the idea of denying retired staff the Staff Travel Concession after a time equal to their service time. I seem to recall that ST is not a cost item and actually generates income - after all Staff are the last on and only take a seat that would otherwise have been empty. And retired staff are right at the bottom of the pile so do not disadvantage anybody.
It is annoying as my wife - ex hostie - loses hers next year, but her brother in law - retired Qantas can use his Qantas concession on BA.
Also silly that had Hawker750 joined another airline after taking early retirement from BA, he would be able to use that airline's ST concession on BA. (Like many EX BA people joined Virgin and now use Virgin ST on BA)
It was a very mean decision on 2009.
