With all the management changes going on now, and S.S. being put in the CPT seat, there might be a light at the end of the tunnel here.
S.S. has been in favour in the past for right to left seat upgrades. I.M. was totally against. So maybe now they might be rethinking to do that, at least on A330 since that fleet will become basically a mix of 320 and 300 flying. A330 will loose most of its glamour destinations in the next two years, taking over a lot of subcontinental flights from the A320 (babybus will become the moneymaker as long as the crisis looms around the corner).B777 will take most high profile destinations.
So yes, right to left on A330 might become a possibility again for upgrades. This doubles the training capacity in Doha so things might go a bit faster again...
