This is a question of passengers not following instructions of the cabin crew.
I have seen many Indians standing up when the flight lands even though seat belt sign is on and announcement made repeatedly that passengers be seated with seatbelts on till aircraft comes to a complete halt.
So how can you blame airlines or cabin crew.
It is rubbish to say that there is discrimination on Asian passengers.
Can any one say whether all Indians are treated properly in domestic flights? If a passenger wears a suit he gets preferential treatment than a passenger in dhoti.
If a foreigner is on board all cabin crew attend to foreigner first!
Discipline and orderliness is the word. Follow the instruction and avoid inconvenience.
Using mobile phones, moving around in the flight when asked to be seated- obviously is a fault.
It is unfortunate that because of 12 misbehaving persons 150 others had to suffer.
