Some JAL flights/airports not bookable with Avios? (In particular, KIJ)
So I'm traveling to Japan this September and found that there's great availability on JAL for using Avios on Intra-Japan flights. However, when I search for flights to/from Niigata airport (KIJ) I receive the "British Airways and its partners do not fly this route" error message, though I know JAL flies from there to Sapporo-Chitose and found flights on the day I'm trying to travel (KIJ-CTS on September 16). I've tried to use the JAL website to search availability, but I've found it to be extremely hard to use.
Any thoughts?
