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.

it’s cute you think that’s going to show up in lower ticket costs instead of the company’s profit margin.
