In terms of job-security I would look for a permanent position with the top players in the market. Netjets Europe and Flexjet Europe will or are recruiting. Especially in NJE the demographics point towards a surge of mandatory retirements in a few years from now. Even to keep the current fleet appropriately crewed, a steady stream of new intakes will be required and upgrades to captain won't be a thing of 10 years, but rather of 3 to 5 years, depending on previous experience/flight hours.
