You are correct Raw Data, but as far as I am concerned my passport is mine and if an Airline RSOMAN has to hold onto their pilots passports to stop them jumping ship doesn`t say much for the Airline does it............????? Anyway heard or Freedom of Choice. A pilot can work where he wants to work. Still saying dont give them your passport, I would immediately be suspicious of any Airline asking for mine.. In fact I would pack my bag with or without "greener pastures".
