If you travel on an Asian airline between the US and Asia you will generally find more Asians than you would on a US airline. You will also find more French on Air France than you would on AA, for example. Unless you believe that you will somehow be discriminated against as a "round eyes", you probably should prefer the Asian carrier. The food, service, seats, and entertainment will likely be better. There is also the intangible benefit of being immersed in the culture as soon as you leave the US, and less chance of being squeezed in your seat by an adjacent fat American.

I flew KE from NRT to ICN this summer and was treated very well even though it looked like I was the only Westerner in business class.
