Xiengkhouang airport is very small like other many regional airports. It is spread out on a desolate plain.
The Airport building is small and somewhat deserted.

Passing by the exit, there is a booth, as in the picture shown above, everyone has to report to this booth on entry and exit.
In this case it is the local people who have to pay, not foreigners. If you skip reporting to this booth, you might have problems. So if you arrive or depart by air, please show your passport at the booth.
