Well if the union got busted, that was due to some guys being over smart! And now alteast we dont have too many last minute disruptions because the PICs grand niece was offloaded because a revenue pax (foolishly?) turned up on a full flight at the last minute (hey - dont u realise We take our "un paid" holidays at the same time as you?)and other similar incidents!
Air India Express people leaving appear to have nothing to do with the absence of the AI union. I doubt think they have the same terms anyway with the AI guys!
