I don't think anyone knows how JS
is doing. They are fully state ownd and also in charge of airport operations in the DPRK.
Scheduled flights at the moment are:
FNJ-BJS vv. on day 2 and 6 with IL6
vv. on day 1 and 5 with TU3
FNJ-SHE vv. on day 3 and 6 with TU3
FNJ-VVO vv. on day 4 and 7 with TU3
Destinations such as BKK
etc. are now only on charter basis. Ops into SXF
stopped several years ago. During the last few years, there where several Air Koryo planes in ZRH
and other airports in Europe.
There are seasonal flights (mainly during summer) with China Northern or China Northwest, mainly flying PEK
-FNJ or PEK
Last year, Asiana and Korean Air operated charter flights (partly loaded in CRS)
