No limit you seem to forget or you never knew that Americans have to pay taxes to the IRS no matter where they live and work. I know the US is one of the few countries in the world to do that but if your going to pay taxes anyway you might as well live and of course work in the US for a Major.
You will work less and make more money than banging away for EK. It goes without saying you will be treated better too.
I’m starting to believe that the Banjo picking pilots that don’t want to go back have some other underlying issues. Some of those issues might be perfectly legitimate like age or they don’t want to fly a narrowbody but if I get hired soon I’ll be a captain there in under 4 years. Quicker than at Emirates.
Right now there is no airline in the EU that can compete with a US Major pilot contract so I can imagine nearly every pilot in the world wanting to fly for the Majors or at least have a contract like them.
