Do Dragonair 33A have PTV?

港龍航空的所有33A和33R都有PTV。但33R就沒有的。
Safety demo在33A上當然是用video。
而且港龍的航機上不會有ISM(inflight service manager),最高級都只會是chief purser(總艙務長)。只有國泰的航機上才有ism。

Dragonair only have PTV fitted on their 33R so that PTV is not avaliable on their 33A...
However, safety demo is made on over head TV and by crew as well at the same time... By nevertheless, sometime the ISM may decide to do a human safety demo only instead for various reason...
