David Dao's daughter has said she was "shocked and horrified" by his treatment at the hands of United Airlines during an emotional press conference.
"My dad is a wonderful father," Crystal Dao Pepper said. "He has raised five great children who will go on to do great things. He is a loving grandfather. At the end of the day he is the person we are trying to protect and take care of."
It came as Tom Demetrio, Mr Dao's lawyer said he will "probably" file a lawsuit against United Airlines after he was violently dragged off a plane when he refused to leave an overbooked flight.
"The laws are there for the protection of each of us," he said a press conference.
"They have treated us less well than maybe we deserve. I conclude that based upon hundreds; literally hundreds, of tale of woe, of mistreatment by United, we want fairness in how people treat us, we want respect and we want dignity."
Asked whether Mr Dao would sue the airline, he replied "probably."
Mr Demetrio also said that Mr Dao suffered a concussion, a broken nose and two broken teeth during the incident and that he no requires reconstructive surgery.
He said that if Mr Dao does press legal action he will be "standing up for passengers" everywhere who have been mistreated not only by airlines, but by corporations."
"I must say I don't think it's limited to the airline industry," Mr Demetrio said. He said he thought "corporate America needs to understand that we all want to be treated with the same respect" as "they treat their families".
Mrs Pepper said that on behalf of her dad and her entire family, she wanted to "express gratitude for huge outpouring of love and concern from all around the world the last few days".
"It has been a very difficult time for our entire family and we are truly grateful for your support. We were horrified and shocked and sickened to learn what had happened to him and to see what had happened to him," she said. "We hope that nothing like this in future ever happens again".
Meanwhile, Canada's transport minister has warned airlines operating in Canada that the federal government will not tolerate the forcible removal of passengers from overbooked airplanes.
Marc Garneau sent a letter to the heads of every airline flying in and out of the country to warn them that an incident like the one that injured an American doctor earlier this week cannot happen in Canada.
