There is some rationalization underway in the Japanese airline business at the moment. JAL and ANA are both taking control over smaller operations as a result of the difficulties that COVID has placed upon them. However, even before COVID reared its ugly head, JAL had created a new subsidiary. This is called Zipair. I recently read that it is due to start operations soon which surprised me because I thought I had seen its planes before. It turns out I saw one of their 787s as it was parked up at Narita when the flight I was on was taxiing in after landing. I guess that airframe hasn’t had much use yet.
