Good money for a stepstone? No. On top of the bond you have to consider moving everything/everyone to and from the Middle East. It has skyscrapers but it really is the Middle East. Especially on Human Rights, Workers' Rights and Expatriates ' Rights. The cost of leaving may be overwhelming and probably comes at the least convenient time. They will dump you like a b**ch especially when you have health or family problems. Or you may be forced to take a huge financial loss to rescue what's left of your family or health.
Job outside aviation. Most definitely. Works much better for me.
