TV commercial for Hong Kong Airlines brand campaign. The idea is that the flight attendants are equipped with youthful heart and energetic physicality to provide the best for the passengers. First video in English, second (identical) in Cantonese.
Hong Kong Airlines has made it compulsory for their cabin crew to learn Wing Chun, a famous Chinese martial art which focuses on close-ranged battle.
It’s said that it will help the flight attendants to be better prepared against drunkards and troublemakers, which the airline encountered every 2-3 days.
I don’t think the lesson is of much use though; you can’t punch a passenger regardless, not in front of dozens of other on-flight customers. Besides, martial art is not something that can be learnt in a few hours, or even days. The situation might end up worse if the flight attendants attempt the techniques.
