Working as cabin crew in Middle east is totally different than in Europe. here, you are just a cheap labour force, and you don't have any unions that might protect your rights.
Yes, there r locals working as crew! But, when u ask them why, they really have weird explanations ( "i want to meet the girls from all over the world", "i want to travel", "i want to have parties" and so on) Like they can't do all these things with all the money they usually have and get benefits from the government.
