787-9 (SS9) Seat Config is also out and first flight will be NRT-CGK JL725/726 from 01Jul.
This means that the 1st 787-9 originally scheduled for Apr delivery will be delayed while the 2nd 787-9 will be sometime Nov.
Total seats 195 (44C/35PY/116Y) which I think would become the roomiest/least dense 787-9 around.
