Upgrade & Award Space from Yakushima (KUM)

Yakushima Airport (KUM) is a small station in Yakushima, JP with nonstop service to 3 destinations, served by Japan Airlines. Because the schedule is limited, an upgrade or award opening on a Kajiki flight rarely lasts. 2LNR checks every KUM nonstop for confirmed availability, so a rare opening doesn't go unnoticed.

Data current as of July 22, 2026, refreshed on an ongoing basis as new schedules and seats are confirmed.
