Narrative:

Captain informed purser that a 747 crew flying ahead of us to ZZZ2 was experiencing moderate to severe turbulence. The captain briefed us on the expected turbulence and also the passengers. The flight attendants stowed all carts; galley doors and picked up service items. We had time to complete our compliance checks and secure the cabin before the moderate turbulence occurred. The seatbelt sign was turned on and captain told us to take our jumpseats. We were at an altitude of FL370 at the time of the turbulence. We experienced 45 minutes to 1 hour of moderate turbulence and 8-10 minutes of severe turbulence. I encouraged our purser to continue to remind the passengers over the PA system to remain seated with seatbelt fastened; remain calm and recline their seat for airsickness. One business class passenger walked up to the business class galley holding a vomit-filled comforter during the moderate turbulence. We firmly told him to return to his seat and fasten his seatbelt quickly! We were unable to continue with the follow-on service. The captain informed us that it was safe to prepare the cabin for landing. I checked all the business class passengers personally to see if they were all right physically and emotionally. Our passenger who experienced airsickness was given ginger ale and an icepack for his forehead. He was extremely embarrassed about vomiting; and he apologized to us for leaving his seat. The other passengers stated that they were concerned and frightened; but relieved to land. Upon approach; the captain informed the purser of a faulty landing gear indicator light. We prepared ourselves for a possible emergency. Fire equipment was waiting for us at the airport. Fortunately; we landed without an incident. I am so grateful to the 747 crew and the captain's advance warning of the possible severe turbulence. We had enough time to prepare our passengers and the cabin and harness in our jumpseats. In my decades of flying; I have never experienced severe turbulence. What a ride!
