We are planning to travel from Lhasa to Tunxi. When we did a search for air tickets in kayak, we find flights that take us from Lhasa to Tunxi , via Chongqing. However, they are different airlines. [The first leg from Lhasa to Chongqing is operated by China Southern, while the second leg from Chongqing to Tunxi is operated by China Eastern]
There is only a 2 hour layover.
So how does it work? Do we have to go through immigration, collect our luggage at Chongqing and recheck in at China Eastern, and go through immigration again?
If that's the case, is 2 hour layover sufficient?
