Only a small fraction of current flyers get window seats. And the view from the isle seat or middle row is non-existent.

And that's before we talk about night flights when there's nothing to see, flights over water when there's nothing to see and so on.

So yes, I'm sure some people like windows. But the majority have demonstrated that they're just fine flying without them.

But are you willing to pay 10-20% more for that joy? I personally would rather pay less money to fly, not get to see out the window, and spend those dollars on, say, a fancier meal at the destination. Or to have an extra day at the destination if my trip length is money-bound rather than time-bound. Or put those dollars towards an extra hour of childcare. Or … I have so many uses for dollars that give me more utility than “see out the window while flying”.

Where that number comes from: they claim 50% reduction in fuel consumption, which sounds doubtful to me, and fuel is about a third of flight costs, and I’m making some generous assumptions around perfect competition.

Make the entire hull 'transparent' by wall covering screens. Think The Sphere in Vegas. Some fans to blow the wind through your hair, and now you are gladly paying extra for the bird-like experience ;)

Skylights, Or floor windows for the freaky

Bullshit. Last time I flew internationally, only two of the eight seats had window access.

Interior isle seats cost as much as window seats in airlines that charge for position. People just want space.

Also the screen sizes they are showing have got to be exceedingly heavy.

Make the floor transparent.

I'm fine with not looking out of the window if the seat is comfortable and I can get to the bathroom more easily. And I'm sure I'm not the only one. Window enjoyers such as yourself will still be able to get the window seats.
