Problem with that is that most airlines like to keep their planes in use as much as possible. With a airplane configured for just sleeping it's only useful for a third of the day. There are also problems with getting the FAA to approve the layouts and safety features for sleeping passengers. I found this great Quora thread on the same question, with some interesting history and thoughts https://www.quora.com/Why-arent-there-any-sleeping-seats-multi-layers-on-airplanes https://www.quora.com/Why-arent-there-any-sleeping-seats-mul... Apparently FAA regulations requires people to be sitting up for takeoff and landings so that adds a bit of a wrinkle too.

Yea I have no idea how you'd pack that many people in without making someone have to climb a ladder, which is a non-starter. Apparently FAA regulations requires people to be sitting up for takeoff and landings so that adds a bit of a wrinkle too. That was my assumption too but I have yet to find any documentation of that anywhere. I've flown since I was 18 and a good portion of my family are Captains or F/As and they haven't run across that either. Maybe I'm looking in the wrong place. I think a niche airline might be able to make it work, but since running an airline is basically a no margin business, it's not worth taking the risk.

  Might be related to this, "For airplanes having a seating capacity of more than 44 passengers, it must be shown that the maximum seating capacity, including the number of crewmembers required by the operating rules for which certification is requested, can be evacuated from the airplane to the ground under simulated emergency conditions within 90 seconds."
