Korean Air face criticism for its handling of an on-board incident

   Korean Air has said guidelines will be revised for crew to react "firmly and actively against in-flight violence", after facing criticism for its handling of an on-board incident.

   US singer Richard Marx said last week that he had intervened to help restrain a disruptive passenger on a Korean Air flight from Hanoi to Seoul, saying the crew had been "ill-trained" and "ill-equipped.
   The airlines said it would also review the use of Taser guns on board.
   According to the news agency, as part of the changes, the airline said it would be providing more training to staff and hiring more male flight attendants, making sure at least one male is on duty in the cabin for each flight.
