I've just landed from a 13 hour daytime all the way flight from China. We flew over China. Mongolia, Russia etc and the scenery below was breathtaking as it was clear.
However, I was apparently, one of those passengers, because, having booked a window set to look out, I refused to pull the blind down until after lunch, some 4 hours in.
Fellow passengers were huffing and blowing but that just made me more steely resolved. It was a daytime flight, them wanting to sleep meant they needed to wear the slumber shades provided (no-one seemed to bother).
WIBU to keep it open to see the mountains?
