Last FO upgraded on the 777 joined May 2010. He has around 1600 pilots junior to him on the seniors list, the majority of them are 777 FOs, and there is a group of DECs towards the end of 2012. There are between 40 and 70 commands on the 777 this year, depending upon which day of the week it is.
Half of the planned fleet of 380s will be delivered by the end of this year. So when the Capts and FOs from the 33/4 fleet are included, new joiners on the 380 need people to leave to make room for their command.
It would appear that the quick commands are over.
