We have all been there. The airline overbooks your flight and offers a $200 voucher to miss your flight and leave the next day. No one volunteers. Eventually, the voucher price creeps up enough (maybe a free night at the airport hotel is thrown in) and a passenger or two agrees to miss their flight. And, when no one volunteers, apparently, the airport police may drag a random passenger off the plane.

In a video circulating the internet, this scenario played out on a United Airlines flight outbound from Chicago (the airline’s base of operations). In the video, the passenger, who claimed he was a doctor and was worried about missing his flight because he had patients to see, was left bloodied and disoriented after Chicago Department of Aviation security officers dragged him off the plane. After the video aired on social media and went viral, United tweeted that the passenger refused to leave, and United CEO Oscar Munoz later apologized for having to re-accommodate the customers. On a flight two weeks ago, United had a similar response when airline employees told two girls they could not board a flight because they were wearing leggings.
