Dr. David Dao, the Kentucky physician forcibly dragged off a United Airlines flight earlier this month, has reached a settlement with the airline, his attorney announced Thursday.  Dao’s attorneys called the settlement “amicable,” but did not disclose the terms of the deal.

In the news announcement, which circulated on Twitter, Dao’s attorneys say United “has taken full responsibility for what happened on Flight 3411.”

The physician became a symbol of mistreated passenger rights after a video showing Dao being dragged down the aisle of the flight by Chicago Aviation police officers at O’Hare airport went viral. Dao was left with a concussion, a broken nose and two missing teeth, according to his attorney, Thomas Demetrio. At least one officer in the incident was placed on administrative leave.

In an interview with the Associated Press published Thursday, United CEO Oscar Munoz acknowledged he “messed up” with his initial response to the incident.

United also issued a report Thursday about the incident on United Express Flight 3411 — and detailed several new policies to deal with overbooked flights, including increasing the amount of compensation that can be offered as an incentive so passengers volunteer to be bumped off an overbooked flight.

Calling his client “the unintended champion” for airline changes, Demetrio hoped other airlines would follow United’s lead and reevaluate their procedures.

“I sincerely hope that all other airlines make similar changes and follow United’s lead in helping to improve the passenger flying experience with an emphasis on empathy, patience, respect and dignity.”
