Just flew the A380 business class for the first time. What a great experience. However we sat in the middle two seats right behind a mom, dad, and 3.5 year old daughter. Mom and daughter were in the middle seats while dad was in the single seat by the window. Before we even took off the girl was loud already. Screaming. Not crying but just being loud as if she were on a playground. It continued throughout the flight. I saw her head from time to time above the seats meaning she was standing on the seat. Mom and dad made no attempt to tell her to be quiet or get down. She didn't sleep once one the 8 hour flight from SYD-SIN. Just really annoying to me because of how loud she was and the parents not doing anything. Luckily I had noise canceling headphones for most of the flight but at times I'd take them off and I could hear her. The ONLY time she was quiet was when we landed and pulled to the gate. Go figure. What are your thoughts on loud kids who think the airplane is a playground? Kids are tough to control at that age or inappropriate?
