Frequent fliers in China, especially those in Shanghai and Beijing, must be used to the frequent flight delays by now. Nobody likes it, but coping with delays that can be hours has become a way of life at airports in many major cities. Most airline passengers on domestic flights have resigned themselves to the fact.

However, there are some who refuse to come to terms with the reality that their flight is unlikely to take off on time. They do the most cowardly thing and take it out on the helpless ground staff and cabin crews, most of whom are young women.

Air rage has become an all too frequent accompaniment to flight delays, graphically laid bare by video footage showing boorish passengers attacking airline staff and destroying property at check-in counters.
