Having just retired from a major European airline flying totally glass cockpit aircraft, I am somewhat disappointed with some of our less experienced flight deck members, who blindly following the green or magenta line, don't even know what countries they are flying over, let alone which of the displayed airports are suitable for diversion. I would certainly not recommend Samos for a diversion on the way to Turkey or the Middle East, although it is displayed by the data base.
I may have been flying these routes for 30 years, but still get the map out, much to the surprise of my fellow crew members.
