This relates mainly to long-haul day flights from East to West, but not exclusively.

With respect to window blind shutting, what is BA's current practice in CW (or WT+, F and WT for that matter) on day flights from East to West (e.g. NRT-LHR). For 747s, Is there a difference between the top deck (shutters closed?) and the lower deck (shutters open?).

If the crew come round and shut the blinds, what is the etiquette towards gently opening them again? Does anyone mind if you do? Will you get lynched by either CW cabin crew or pax? Does anyone have a view on what is the "done thing" if you have a window seat, have a 12 hour flight, and want to look out of the window once in a while?

In my experience, there are many carriers where the cabin crew come round and forceably shut all the blinds for 12 hours - no discussion. There are others that are relaxed and don't mind a few being open.

My personal view is that day-flights are day flights (and the best way for most people to overcome jet-lag east to west is to stay awake). However, if you want to sleep, that's what the eye patches are for. I'd rather not have a darkened cabin for 12 hours. However, maybe there should be an upper-deck / lower deck rule for CW?

West to east long-haul daytime: similar issue as above

West to east long-haul overnight: no question: blinds shut, and if you open them mid-atlantic 3 hours in, when everyone is asleep, a good BA lynching should follow
