What premium would you pay for something like that? Say on a flight from SF to Tokyo (or some other long haul flight)
It would save a full day of recovering from a sleepless night cramped in a small airplane seat. When staying a week it would effectively add a day, and justify a 15% difference. And night flights are usually cheaper or sometime even the only option for remote destinations so I'd still take it at a 30% premium for some of the shown systems. It looks super comfortable and offers more privacy. (although you may not want people to have too much privacy on a plane)
It fits the same number of people in the same space, we shouldn't have to pay much of a premium.
