The configuration that is shown on www.seatexpert.com (K04) is already obsolete, since the Old Solo Seat has been phased out a few years ago. But the solo seat in the 744 that is the least desirable is 5G, which is in the middle of the aircraft, being near the bar, galley and it faces a lot of traffic.

I have a feeling that seatexpert won't be updating JAL's configuration page anytime soon.
