Great report! Enjoyed it a lot, especially the train and panda pics! have yet to fly PP but it looks like a pretty good product. I don't think I could do that for an Asia flight myself but looks plenty fine for a 5 p.m. departure to Europe when I wouldn't probably sleep anyway. Or a daytime flight from Europe back to the US.
Funny about the turbulence a little east of Japan. I've flown back from East Asia to the US quite a few times and without fail there is pretty significant turbulence right about that spot every time. It's pretty reliable.
Thanks again and looking forward to your next one!
