Hi Steve,
Yes you are correct. I come from China and moved to the US in 2007 for graudate school. My parents have flown into LaSa (airport at 3,570meters), the capital of Tibet back in 2006 and they had AMS symptoms.
The commercial flights opened huge tourism markets for regular Chinese people. Previously most people would visit Lasa by train or by bus, it takes 4 days from Beijing to Lasa. All the travel agencies have been educating tourists to prevent AMS.
I have not visited Tibet yet! I have climbed 45 state highpoints in the US but not much in China! I miss home.
