The ability to be allowed to look out window is a prime determinant of choosing airline and aircraft for me.
Well don't book on United then. Not a 787 but on a recent 10 am departure from London they had served food and had all the window blinds shut by 1200 UK time and they stayed shut until about 30 mins before landing. Any transgressors were aggressively told off by the few cabin crew who were not snoozing off their night out in London.
Daytime crossing of the high atlantic in good weather can be stunning, plastic window trims and crap IFE is not.
