Dude, your plan sounds great but there is an issue. Because of the bond you have to stay 5 years with EK. The pay isn't that bad, but forget that you'll save a lot of money. A single EK Pilot will find enough amusement
So you'll go back to the US after 5 years as a FO with plenty of WB time which doesn't help you because the system in the US is based on seniority. You'll find yourself at the end of the seniority list with a regional carrier. Ask yourself if those 5 years with EK will be a career booster.
