Your perspective makes sense considering you haven't lived the US airline life. I hate to be the bearer of bad news but $210,000+ USD per year at 65 hours a month disappeared after 9/11. You won't find it unless you have 25 years of seniority. You might have to exchange your husband for one who already has 20 years in at a Legacy airline. Maybe General Lee? I'm kidding! Bad joke.
But all kidding aside you might be surprised by what the airlines are paying in the US. US Airways is hiring. First year pay is $3,000/month BEFORE taxes. After 4 years it's $5,200/month again before taxes and that assumes he is on the 767.
At the high end of the scale you have Delta. If your husband could get hired you are looking at about 5k/month first year and 9k/month after 4 years. Not bad at all but definitely nowhere near what you are making right now.
Your husband will never fly 100+ hours per month at EK. Your sister does but so do flight attendants in the US. He probably works harder at EK than he would back home but he also makes a lot more than he would back home. Tell him to spend more time on the swap board and he can alter his line from high to med-low time.
I'm certainly no kook aid drinker. I can complain with the best of them. Emirates uses me and in return I use them. There are no happy family airlines in the US (maaaaybe SWA). Use every benefit you can to the maximum and try to minimize the amount of work you put in using every legal means at your disposal. Keep an eye out for better options. Obviously there's much more to life than money. But figuring out the balance is tough.
Assuming he's a captain your husband would have to make about 260k/year before taxes in the US to equal his salary in dubai. If you have kids you might have to bump that up to 280k-300k. Here is a website with all the airline salaries so you can see exactly what he will make. Good luck
