Well, I've said it before but I will say it again, I flew very happily as a DC-10 captain for a Part 121 operator based in JFK for three and a half years. We had so many nationalities flying for us that I wouldn't even know where to start.
It really does work both ways chaps.
One thing that I would agree with is that the US unions are much better than BALPA (which is as much use as t*ts on a bull.)
