The thing that will really screw over the A330 F/Os is not the DECs on that fleet. It is the fact that they will then go across to the A380 as Captains while the F/Os who have already suffered for the company bottom line will move across as F/Os (I doubt there will be any more upgrades on the A330 now) and then have to do another 2,500 hours before they can be considered for an upgrade on the A380! This will literally add years to their time in the right hand seat.
