White Knight left BA under questionable circumstances and he hasn't forgotten it. He is a management lacky who goes into the office almost everyday trying to "save" the company and justify why he left BA.
His hostility towards Americans comes from another angle. He is jealous.
I don't know any narrowbody FO flying in the states living in a RV. After all when SW, DL, and AA just to name a few all pay their 737 FOs well north of $100,000 and they only have to work 12-13 days a month who wouldn't want to fly for those conditions, nationalites aside.
Then when you look at the widebody pay scales at the US majors you realize how underpaid we at EK are. A closer look tells us they only work 8-10 days a month and then it really hits home what EK is doing to us.
But it is good for you White Knight. Did you spend all of your "bonus" yet?
