United Airlines Controversy Timeline: Full List Of Events After Passenger Dragged Off Plane

United Airlines disastrous "overbooking" nightmare began just a few days ago- but the company managed to pack in a whole lot of controversy in such a short time. A full look at the company's public relations fiasco shows how the situation escalated and where the airline stands now.

Sunday, April 9: A 69-year-old doctor named David Dao was forcibly removed from United Airlines Express Flight 3411, bound from Chicago to Louisville. Video emerged of aviation security officers dragging Dao, who is screaming and bloody, down the aisle of the aircraft by his arms. Fellow passengers could be heard shouting at the officers to stop. United Airlines said it randomly selected Dao — along with three other passengers, who left without incident — after nobody volunteered to de-plane in order to make room for three company employees who needed seats. Passengers who witnessed the incident said Dao explained to officers and crew that he had to work at a hospital the next day and so couldn't leave the plane.

Monday, April 10: United Airlines issued its first response to the incident on Flight 3411 via Twitter. "This is an upsetting event to all of us here at United. I apologize for having to re-accommodate these customers," said CEO Oscar Munoz in the statement. "Our team is moving with a sense of urgency to work with the authorities and conduct our own detailed review of what happened. We are also reaching out to this passenger to talk directly to him and further address and resolve this situation."
