Two final points before I disappear:
The comment about passengers struggling to adapt to foreign crews is quite possibly the most ridiculous thing that I've ever read on here (and on a personal note, I'd take a young Pole stewardess any day over some of the fishwives plucked from closer to home).
I will second Hearty Meatballs in regards to the ME carriers. Also, I'm VERY surprised that if you've educated yourself in world issues that you'd even consider working in countries with such despicable human rights records.
