Flying Los Angeles London. Took off at 6.30pm the perfect time for light. I was on Virgin a 787 where like United airlines and Thai as soon as you take off they darken the windows I’ve complained on all three airlines. I get ‘People want to sleep’. Which is more like they want people to sleep less for them to do. In fairness the Virgin airlines crew were very nice and unlocked the window’s so I could enjoy this view.
