That's rich, Jane...a little bitter are we?
I've heard European accents at NWA, UAL, CAL, America West, Fedex, etc.etc.. not to mention nearly every regional.
I also know serveral corporate types that have green cards only.
We also have several European (among other regions of the planet) crewmembers at our US B747 operation.
This doesn't bother me in the slightest. They bring a lot of good skills and interesting personalities aboard. They play the seniority game like everyone else...
These sorts of comments always come up when things get tight in the job market...don't forget there are a lot of laid off people here in the US that might share your narrow view
about 'foreigners' flying for, in this case, US firms.
