Narrative:

This incident occurred during flight downtime. That is, the time in between dinner and breakfast service. Most, if not all, passenger were sleeping or watching the movie. The seatbelt sign was already on, so when the aircraft dropped, most passenger were secure, or at least the last time we checked (approximately 15 mins before) they were. If all flts were required to have seatbelt sign on during cruise flight and various new placards on tray table, maybe there would be less turbulence related injuries. I felt that my training allowed me to recognize the reactions of the aircraft and to secure myself. The duration of the turbulence lasted approximately 30-45 seconds. After checking cabin for injuries, we found 2 passenger, who we believe were walking back from aft lavatory, sitting on floor in aisle to secure themselves. There were no injuries, but still there were passenger without their seatbelts on. Our captain was informed of negative injuries and he told me that there was nothing on radar and he was just looking west over miami where thunderstorms were in the area. The approximately location was 35 mi east of miami.
