Not so sure that's such great news for Lhasa.
Probably mostly Chinese there anyway as China began systematically destroying the Tibetan culture decades ago.
The flight lands one at a very high altitude, over 14,000 ft.
The 24hr-long
TRAIN that goes there is mostly above 4,000m/ 13,000 ft and has one 5,072m / 16,640 ft pass. They have (or had) some oxygen-supplemented rail cars because of the problem. There were medical articles written about it. Here is one, with interesting stats:
AMS on the Tibetan train As a comparison, the Syangboche airstrip 3780m /12,400 ft in Nepal is closer than the Lukla airstrip for those going to the Everest region. However, it is rarely used commercially any longer in part because of AMS problems. In the past, typical users of this airstrip were mostly sedentary tourists who visited the former(?) Hotel Everest View that has or had oxygen available, or who were going lower to Namche.
