I think there is some hiring on the 737 still but nearly all new F/Os in 2009 will be CTC cadets, whom the company have openly told our union will not be offered permanent employment, unless there is a drastic turn-around in global economics. As for having a say in which fleet you are on or which base you would like, well maybe in the golden summers of 2005/6, but not any more.
easyJet's stated intention for the future is to offer senior first officers "summer commands", hiring 6 month contract F/Os to fill the RHS in the summer period and then showing the contract F/Os the door to allow the "seasonal captains" to return to the right hand seat for the winter season.
CTC and ezy managers call it "Flexi-Crew", personally, and I know I'm not alone amongst ezy pilots from either seats on this one, I see it as the end of easyJet as a decent employer. I think anyone wishing to join, whatever their experience level, should bear this in mind before turning cartwheels of joy at the prospect of joining our ranks.
