There are no direct long-haul flights to Tibet. You will probably have to stop over in Kathmandu, Beijing, Bangkok or Hong Kong before reaching Lhasa.

The primarily gateway to Tibet is Kathmandu from Nepal. Lhasa can be reached by air as well as land from Kathmandu. Air route from Bangkok or Hong Kong will include several stop-overs in Kunming and Chengdu.

In theory there are a number of land routes into Tibet. In practice, however, most travelers only use one of two officially sanctioned routes. Kathmandu to Lhasa via the Friendship Highway or Golmud to Lhasa via the Qinghai-Tibet Highway.
