CHICAGO ― An overbooked flight from Chicago to Louisville, KY ended in a bloodied uprooting of a customer from his seat and dragged down the aisle towards the entrance of the aircraft.

After passengers were seated on the Sunday flight with no seats to spare for a few staff members, the airline announced that it needed to take volunteers for a flight the following day.

The compensation issued by United for taking up the offer to fly the next day included $400 and a free hotel. United failed to recruit volunteers even after it had bumped up the offer to $800. The airline then randomly selected four passengers to remove from the airplane.

Though one couple cooperated with United and left the aircraft, one man, a doctor “who needed to work at the hospital the next day,” according to one passenger on Twitter, refused to give up his seat.

The man was then forcibly dragged from his seat after being confronted by three law enforcement officers in Chicago aviation police uniforms. Videos taken by multiple passengers show the man’s face struck by a seat armrest during an entanglement, with officers dragging him by his feet down the isle.

On March 26, the airline turned away two girls wearing leggings, justifying their removal allegedly due to dress code violations.
