Welcome to sardine air: Airline introduces triple bunk beds in economy

I've been wanting this for so long. I hope they do it.

With triple-decker bunk-beds stacked from floor to ceiling, it looks a cross between a school dormitory and the sleeping quarters on a troop ship.

But thrifty fliers take note. German airline Lufthansa is considering introducing just such an economy sleeper cabin on its long-haul flights.
