Any ideas which industry enabled this route " I know back in '80s JL operated KIJ (Niigata) - KHB (Khabarovsk, USSR back then) and KMQ (Komatsu) - SEL (Gimpo back then) by 727-100. It was not a daily flight. 727-100 was based at NRT. Aircraft was serviced and catered at NRT, with FAs on board aircraft was ferried to KIJ and KMQ prospectoively to do KHB and SEL flights."?
