In life we all have unwritten rules like how far behind someone you stand while you are in line or the “nod of recognition” you give someone if you make eye contact while they are walking toward you.
There are lots of these about airplanes, famously about 3-deep-seats.
But I’m curious about the unwritten rule for the window.
To me, if you are in the window seat, unless someone specifically needs the window to be open for motion sickness or something, you are responsible for closing the window once the plane is at cruising altitude so people can sleep if they need to. If you dont do that, I find it a little grating.
Curious what other folks think.
I’ve partially closed one before when I was by the window to help block some of the light but still allow me to look out. It was also a half-filled plane and I had the whole row. If someone beside me was sleeping or reading and it was too bright I would have closed it fully.
Just be aware of your surroundings and others. Too many people are so deep into their own stuff they don’t see others around them or what might help them.
