Doesn't ethnic traffic mostly fly on their own country's carriers? I've always thought that someone who doesn't comprehend English well from China would stick with Chinese carriers overseas whereas Americans (including Chinese-Americans) would tend to choose the US carriers?

Many Chinese-Americans don't have that great of a grasp of Chinese anyways and wouldn't know the difference between "ni men" and "nin men" or wouldn't care that much, I know I don't care too much.

I've flown Air China before, their English is quite bad. Though it is kinda neat that they speak English on their domestic flights as well.
