Why going to the sandpit?
That is the question. I think most of us are here because we had too at some stage because there was no alternative. The pay is not good but also not bad, you can save some money but you will not get rich. You will get a good valuable type-rating on an Airbus or Boeing and fly on an interesting network all over the World, seeing things you would otherwise never see.
But there is also a big price to pay as an expat here, you are not welcome here by locals, you are at best a well paid laborer, social life is mostly limited to expat community, the Gulf Cities including Dubai are rather boring, uncultured and only consumer (shopping) oriented. Furthermore it is unbearable hot, humid and dusty and worst is the traffic which is absolutly dangerous. Specially if you have kids this place is only for a few years and is not a place to spend your career.
