Corliss King, the vice president of Transport Union Workers Local 556, said that assaults have risen considerably in the past few years. She said:“Our flight attendants are the first line of defense, but we should also be protected. So we are looking for the public, federal legislators and we’re looking for our carriers to band together to protect us. We are the most vulnerable.”She continued:“That small number of people that are insistent on behaving unruly, on behaving dangerously, represent a threat not just to flight crews but to our flying passengers as well."The case currently remains under investigation.
