"We are pleased to report that United and Dr. Dao have reached an amicable resolution of the unfortunate incident that occurred aboard flight 3411".
Last year Southwest bumped 15,000 passengers off flights, more than any other US airline. The passenger's lawyer said his client lost two front teeth in the scuffle, incurred a concussion and a broken nose.
During a press conference earlier in April, Demetrio said the lawsuit was meant to "stand up for passengers going forward". The officers who dragged Dao off the plane worked for the city.
David Dao was treated in hospital after aviation police physically removed him from the plane to make space for four crew members on the flight between Chicago and Louisville, Kentucky.
Demetrio said it was "unheard of" for a company to admit responsibility "in the fashion they have done". - It's nearly like you kind of hope you are bumped!More news: US VP Pence warns North Korea: 'The sword stands ready'
Passengers who voluntarily give up their seats on overbooked flights will now be compensated up to $10,000.
No one accepted the offer, and United staff then chose four passengers to involuntarily bump. Dao, a doctor, had refused to give up his seat for a United employee because he said he had patients to see. In a confrontation captured on video, a bloodied Dao was forcibly removed from the flight.
The dragging was a major public-relations crisis for United.
United said some of the changes are effective immediately and others will be implemented by the end of the year.

The department's roughly 300 officers guard the city's two main airports but are not part of the regular Chicago police force. They receive less training than police officers do and can not carry guns inside the terminals.
While not a factor in this month's incident, United also said that starting in June it will pay customers $1,500 with no questions asked if the airline loses their bag.
United has also unveiled a raft of policy changes in the wake of the incident, including offering passengers up to $10,000 to give up their seat on an overbooked flight.
JetBlue is now the only major US airline with a stated policy that bans overbooking.
However, he acknowledges that the attention around the United incident had prompted Southwest to move ahead with dropping overbooking.More news: Bulls' Rondo fined for attempting to trip Celtics' Crowder
