Not sure I would recommend Netjets. 6 Year upgrade for new hires??? Difficult to predict but nowhere near the mark. Although having said that, the forced redeployment of Gulfstream pilots to the Excel fleet? may prompt those to leave creating a few more openings.
No pension to speak of nor any prospect of one.
I don't see how they would be able to attract anybody given the current conditions?
Look elsewhere first would be my advice, there are good opportunities out there.
