How do you get any work done while flying? I find business class to be a very productive time to work, to the point where I usually regret not trying to sleep more on my flights. One of my most productive 24 hour blocks of work ever was SYD-SIN-LHR (my first time on the SQ A380), but I am usually very productive in CW or F on BA, and even in row 1 of CE when it's not just a short hop to DUB or AMS.

By contrast, I find it difficult to even open my laptop in shorthaul Y other than an exit row or bulkhead, and if someone is in the middle seat, it's pretty difficult to work comfortably for more than short while.
