A spokesperson for United said: "Flight 3411 from Chicago to Louisville was overbooked. "After our team looked for volunteers, one customer refused to leave the aircraft voluntarily and law enforcement was asked to come to the gate. "We apologize for the overbook situation. Here's how they did it: pic.twitter.com/QfefM8X2cW — Jayse D. Anspach (@JayseDavid) April 10, 2017 
 
 According to the passenger who filmed the video, United initially asked if four volunteers on the flight from Chicago to Louisville would be willing to give up their seat for $400, a free night in the hotel, and a flight at 3 p.m. Monday. Passengers were allowed to board the flight, Bridges said, and once the flight was filled those on the plane were told that four people needed to give up their seats to stand-by United employees that needed to be in Louisville on Monday for a flight. Passengers were told that the flight would not take off until the United crew had seats, Bridges said, and the offer was increased to $800, but no one volunteered. After two people willingly left the plane, the man in the video reportedly said he was unwilling to surrender his seat because he was a doctor and had patients to see in the Louisville area Monday morning. The man was able to get back on the plane after initially being taken off – his face was bloody and he seemed disoriented, Bridges said, and he ran to the back of the plane. "Everyone was shocked and appalled," said Audra D. Bridges, who recorded the video and gave her account of the events to The Courier-Journal. "There were several children on the flight as well that were very upset." A man was forcibly removed from an overbooked United Airlines flight Sunday, sparking widespread horror after a video of the incident was posted online: 
 
 @United overbook #flight3411 and decided to force random passengers off the plane.
– People are outraged after video surfaced Sunday night showing a passenger being forcibly and violently removed from a United Airlines flight that had been overbooked. As the Courier-Journal reports, four seats were needed on the Chicago-to-Louisville flight so that crew members could get to Louisville for a flight assignment Monday morning. Passengers were told that volunteers were needed to give up their seats and that they would receive $400, a hotel stay, and a flight the following day. They were told the flight wouldn't take off until four people had given up their seats, but no one volunteered. The airline then doubled the offer to $800 and still no one volunteered. A manager then came on board and used a computer to randomly select passengers who would need to leave the flight. A couple was selected and left, and then the man in the video was selected. He explained that he's a doctor and had patients he needed to see Monday morning, but was told that security would be called if he didn't exit the flight voluntarily. He said he would be calling his lawyer, and eventually, three security officials came onboard, pulled him from his seat, and dragged him down the aisle and off the plane. Passengers say everyone on the flight was appalled, and children onboard were scared. The man got back on the plane, reportedly "disoriented" and with his face bloodied, and ran to the back of the plane. A medical crew came aboard and passengers were asked to return to the gate while the plane was "tidied up." Eventually the plane departed two hours late. United has since apologized for overbooking, the Week reports, but no update has been given on the passenger who was removed. Video of the incident from two different angles is here and here.
