That exactly what I've been saying I do! I made the switch from aisle to window. Even though I have no desire to look out the window, I select such a seat for the sole purpose of denying someone who really wants that seat but can't think about anyone else but themselves. (Not all fit into this category but it seems some do and it's just not worth the risk.)

I'll reiterate... I don't mind window seat people looking out while over the grand canyon or something else of interest, but when you're flying over the pacific (or anywhere else), nothing but same same blue sea or clouds, and window people insist on 'blinds open' then they are being selfish when everyone else is straining to see their IFE on an otherwise long and boring flight. I don't care if the blinds are open while everyone is eating, but mid flight with nothing to see? C'mon!

As I said, I've been on several flights where the person sitting by the window has been shielding their IFE screens with a magazine or the safety card so THEY could see the screen. Doesn't it occur to them that by shutting it, at least partly, that both they and everyone else could see?

Totally selfish and/or clueless!
