Realising I was on a 77K (B-KQX), I went to the back to see the new seats and try them out.
Since I was squatting I wasn't allowed much time.
Seat comfort felt good - better than the old TZ and JL domestic iterations I had to endure. Perhaps helped by age of seats.
Didn't really have to touch shoulders with my seat neighbour, who was incredibly petite.
Y was 2/3 full on my SYD-HKG CX100 flight and almost every alternate seat was empty. PE and J were stuffed to the gills since CX162 was cancelled.
