Just did last week - A380, business class, Guangzhou to LAX.
And they are. :) Much taller than the average Chinese girl.
My wife is from China, we flew from Shanghai to LAX last week as well on a 350-900. The planes are impeccably clean and the service is fantastic. They have a great business model that the US airlines may want to copy.
Off topic , but had to look up where that city is. That city was formerly called Canton, China.
Hard to keep up with all the changes in the world. Bombay became Mumbai, Peking became Beijing, Congo became Zaire and then Congo again, etc.
