PGA makes an observation. KLM at the present time can recruit enough pilots through their regular sources. That seems to be the point to me. Supply and demand. If and when that changes (like it did back in the late eighties to mid-nineties) the "free-market" pilots will get their chance. And I am sure his Dutch language skills, and flying time will give him a leg up at that time.
The ex-KLC UK pilots have negotiated through their union (BALPA) a deal whereby the option to switch over to KLM mainline is again available to them. The conditions are indeed that they have to go through the normal hiring process, join at the bottom of the list, but keep their pay scale from KLM Cityhopper until their pay at KLM mainline catches up to that pay scale. Also the condition to learn Dutch is part of the deal. These pilots are already valuable members of the Air France/KLM group, and they now get the opportunity to, if they so desire, to make the switch to mainline flying.
I wish PGA luck and hope the growth spurt that is forecasted will make it possible for him to be considered for recruitment.
