I don't think so many EK pilots moved to DXB because on one morning they woke up with the need to move and live the arab way of life. The point was easy money and easy life for westerners, with maids and king Fadh lifestyles.
Today there is inflation, traffic etc... and the job is just a pilot job, like in many airlines...and people are showing the real reason why they came... $$$$$
By the way, I'm not sure it is more risky to have teenage girls in DXB than is some other west places... locals are not rapping girls everydays...
