Would be great to have those plane models with individual TV screens. The common screen is a fixed program that not ALL passengers are interested or understood. Furthermore, no head sets provided. Imagine a 4hour flight just staring at a silent moving screen? Not too pleasurable flight. kind of bored and just find ways to sleep. Though hard as you can imagine flights to China would ALWAYS have some kind of tour groups. It can be kind of "chaotic, hectic and audible" flight. Bring personal earphones and plug in to personal audio or videos on your smartphones with pre downloaded movies or audios.
