I’m currently on a flight (left 8:30pm so dark out). My seatmate will open the window, look to see what’s going on, then close it. Lol. Why not just leave it open? I personally hate the windows closed it’s like traveling in a tin can not knowing anything, plus I’m prone to motion sickness. I get that in bright sunlight and watching something you want it closed. But on a night flight why have it closed?

Do you prefer open or closed?
