Procedure
I commute and spend many hours as a passenger. I am seeing things that I fear will cause [the company] to incur fines and injure passengers. [On one flight] the Captain turned on the seat belt sign three times in the first two hours; each time making an announcement. Not once did a Flight Attendant ever walk the aisles to check for seat belts. About two hours from landing we entered moderate turbulence for nearly an hour. The Captain announced that the Flight Attendants needed to take their jump seats. No one walked the cabin to check for passenger seat belts. During this time I counted a line of 14 passengers standing in the aisle waiting to use the aft lav. I looked to the rear to see if a Flight Attendant noticed this and saw that the galley curtain was closed. The turbulence was solid moderate; overhead bins popped open and those in the aisles struggled to remain standing; yet the Flight Attendants never asked people to sit down nor apparently did they tell the captain that people were up as he never made any announcements.  I spend at least 20 hours each month in the cabin with these crews and I am certain that a serious injury and an FAA violation are just around the corner.
Captain observed Flight Attendants' non-compliance with company policies and FAR's on several flights as a commuting passenger.
