Viability of stacking passengers in an airplane cabin [closed] - Interior of Airplane with Passengers

I've came across on youtube a new design for stacking passengers in an airplane cabin, that looks at first sight interesting.

What would be the advantages and drawbacks of such a design? Why this is not common in today's airplanes?

Note: I cross-posted this question on aviation stack exchange too, as I wanted to get both technical / social feedback.



Best Answer

I speak only as a frequent flyer who once worked for an airline, not an aircraft designer.

The main point of contention with such a design will the be the trade-off between the extra passenger capacity and apparently significantly weight of those structures.

As as Business Class passenger, I would find those compartments quite confining. The current prevailing herring-bone layout is cramped enough.
