You Can Continuously Smell the Breath of Surrounding Passengers
With slim seating I find you can smell the breath of your surrounding seat mates for the entire flight. When the seat in front of you reclines with their head against the wall of the plane the front passenger’s face is so close to your face. I guess it is like being in an orgy with clothes on. Your fellow passengers can be all over you. And the seats are so hard that for a flight more than a few hours your body aches. Then the bathrooms have large protrusions making it difficult to move. Next the airlines will be charging extra for a clothing optional section of the plane to take advantage of the closeness of the slimline seating.
