Just a correction, whossorrynow's figures for captain's pay are not correct, they're optimistic by about 5,000AED.
Basic salary for captains is 36,140AED (about $9840USD). With 84 hours @60AED = 5100AED, that equals 41240AED (about $11,300 USD).
That is how the figure on the career website is derived.
Captain: Monthly Salary Dhs 41,240 (Basic Salary plus Hourly Flying Pay based on 85 block hours per month)
The figures listed earlier take the basic, 85 hours of flight pay, and THEN add another 75 hours on top. As much as EK would love to wring 160 hours/month out of their slaves, even they can't do that. I'm not sure why you were given the figures you were, except that I would hazard a guess that as usual, the people giving all sorts of advice about Emirates...don't actually work there.
These figures are before any deductions. Which
are correct. As far as allowances, they're pretty much exactly what any unhealthy hotel meal costs, at whatever discounted rate EK could negotiate. Wouldn't count too much on getting rich off the per diems, if you can keep your BMI in check consider yourself ahead.
So no, you won't be making near 12,000USD/month. Put it another way, an EK captain makes less than 10k/month basic to operate a widebody. If you're really making 18k to live in a real country you have to be insane to even give it a thought.
