Every airline is different with what they use for their flight attendant scripts. Generally they would all include the area that you are going to be entering, how long it would take you to get to your destination. The weather, miles of visibility, what the wind speeds are. They will tell you that they are turning the seat belt sign on and to return to your seats and fasten your seat belts.
. You will also hear them tell you to put your seat and tray tables to the upright position. They may also tell you if they will be serving dinner or drinks and that they may be coming through to pick up any trash you may have.
