A man’s refusal to give up his seat on an overbooked United Airlines flight led to a disturbing scene Sunday that has travelers up in arms over airline policies. The Department of Transportation said it will review the incident, in which a passenger was forcibly removed from the Louisville, Kentucky-bound United flight 3411 at Chicago O’Hare International Airport.The incident has prompted one security officer’s suspension and created a publicity nightmare for United. Several passengers recorded the incident on their phones and posted video on social media showing three Chicago Department of Aviation security officers dragging the man, who has not been identified, down the aisle by the arms and legs while other passengers shout in protest. He continued to resist after he was removed and ran back onto the airplane, face bloodied from the encounter.”It was very traumatic,” passenger Jade Kelley said. She did not witness the entire event but she said the sound of the screams still haunt her.
