For those unfamiliar with that incident:

• 2017 United Express passenger removal

On April 9, 2017, at Chicago O’Hare International Airport, four paying customers were selected to be involuntarily deplaned from United Express Flight 3411 to make room for four deadheading employees. One of these passengers was David Dao, 69, a Vietnamese-American who was injured when he was physically assaulted and forcefully removed from the flight by Chicago Department of Aviation Security officers. Dao, a pulmonologist, refused to leave his seat when directed because he needed to see patients the following day. In the process of removing him, the security officers struck his face against an armrest, then dragged him – bloodied, bruised, and unconscious – by his arms down the aircraft aisle, past rows of onlooking passengers. The incident is widely characterized by critics – and later by United Airlines itself – as an example of mishandled customer service.
