Rippa, if I said it doesn't matter, or not, if there are Brazilian pilots at CX would you begin to understand the concept? Yes, it might me good for you to meet up with someone from your own country, but try the diversity route and try being the first.
CX is one of the Foreign Legion airlines of the world. We don't ask where you are from, just can you fly aeroplanes.
I think we are up to 40 nationalities on the flight deck. Not quite as diverse as Emirates, but getting there.
