It is a known fact (and has been for many years) that airlines in the middle east treat their Captains with far more respect than their First Officers.
With this in mind, I have often wondered just why a few, with commands elsewhere, would join a middle east airline as a First Officer...hoping for a command, once again.
Rule 1. Never ever give up the LHS for a RHS elsewhere, and in so doing, put yourself at the mercy of managements who keep changing the plot.
Rule 2.
If in doubt, see rule number one.
However, PT Barnum said it best...'There is a sucker born every minute.'
