Yep, I agree. I didn't use flash for any of the picture because I was worried I might wake up the other pax. I hope anyone planning to take pictures would also be considerate too.

Actually I booked all Y, J and F JFK-HKG in the last 2 months and was planning to write about each of them, but I forgot to bring my camera for the Y trip, and forgot to hand-carry my camera for the J trip. Not feeling inferior at all as I was not trying to brag but to report. Hopefully people would find the information useful. I will probably do a long-haul Y and a long-haul J in the next few months.
