A passenger aboard a United Airlines flight was dragged from his seat and removed from the aircraft as the flight was overbooked. <br /> <br />United had to ask several passengers who had already boarded a flight on Sunday evening to leave as the airline had sold too many tickets. <br /> <br />The airlines had at first requested for volunteers to leave offering cash payments or flight vouchers but as not enough people volunteered they selected four people to leave the aircraft. <br /> <br />The man in the video was dragged out by security officials after he refused to get up from his seat.
