To deal with drunken and disorderly passengers, Hong Kong Airlines flight attendants are trained in kung fu. This, according to the airline, will serve to keep passengers safe and lessen the likelihood of disruptive behaviour.Kung fu is a centuries-old Chinese martial technique that has been practised. It is well-known for emphasising speed, power, and accuracy. When dealing with potentially disruptive passengers, the airline considers that these are key qualities for flight attendants to posses.Hong Kong Airlines is not the only airline that teaches its employees kung fu. Indeed, numerous Asian airlines have followed this practise in recent years. The reason for this is that inebriated and unruly behaviour on flights has increased in recent years.Some people believe that kung fu is a good approach to deal with such behaviour. Others, on the other hand, say it is a waste of time and money. Only time will tell if this practise reduces disruptive behaviour on flights.
