"I personally don't enjoy being woken in the middle of the night by an-
85 pound cabin attendant walking past my first class seat- this causes
the seat to move from flexing of the adjoining floor structure."
I don't want to bring up the past , but I don't know if any of you guys have sat on the upper deck of a Boeing product? That floor moves when anyone (both small and not so small ) walks past!!
Boeing / Airbus - they are just airplanes trying to be as light and cheap to run as possible.
