Redding was fired the same day United settled with Dao, who suffered a broken nose and lost teeth, for an undisclosed amount. The settlement also released the city from responsibility, according to Dao's attorneys. United also pledged to limit use of law enforcement to remove passengers from flights to safety and security issues, reduce overbooking, provide additional employee training and pay passengers on overbooked flights up to $10,000 to volunteer for a later flight. But sources said Redding's firing was not related to that incident.
