Are you serious? They deserve this? We don't even have any idea how their fight started and she's hurt. Not everyone can contain their emotions and even if they did fight in a plane in front of many other people, I don't think they deserve this. They're not even bringing anybody else in the plane into their flight, if this passenger is being inconvenienced in any way because of the fight, she should've approached them or any of the crew and ask them to tone it down (if it was so loud they're being disturbed)
