no worries... I think it depends on the fleet. on the 777 I think there might be more Asian guys, on 320: more guys from US/ south and central America/ Europe with also a few guys from NZ/AUS. I guess 330 and 340 fleets are more balanced though probably not too many Americans as most are on the 320 I believe.
If you are looking for exact numbers, maybe somebody more informed can chime in.
