Narrative:

(Did not have seat belts on) sitting on back jump seat waiting for captain to ask the crew to prepare for landing we hit an air pocket. The 2 flight attendants (myself and another) flew up to the ceiling and hit our heads. I received concussion, and neck injury. Allegedly, aircraft altitude was 6000 ft(?). Had we been strapped in at a higher altitude (10000 ft) I believe this could have been avoided. I have heard that most pilots prepare (the cabin for landing) at 10000 ft. Shouldn't this be a 'rule' considering a lot of 'bad' air is oftentimes found at lower altitudes?
