Sleep?
Sleep? in ecomomy? I fly a lot, (SLF) UK to most of Asia & Pacific, I can hardly walk after 14 hours in an economy seat, I'm 6'4".
I've never slept on an airliner...
Got upgraded to biz class once or twice, and then I didn't sleep because I wanted to make the most of it!!
Oh yes, the post...I always keep seatbelt on, just in case, and I really wish FAs didn't have to keep anouncing signs on/off...
