CHICAGO, April 24 (Xinhua) -- The lawyer for the passenger dragged off an United flight signaled on Monday that his client intends to file a lawsuit.

Thomas Demetrio, a prominent Chicago lawyer representing 69-year-old David Dao, told NBC's "Today" program that its was too late for the United Airlines' CEO to apologize face-to-face to his client.

The Vietnamese American doctor was forcibly removed from a United flight at Chicago O' Hare International Airport on April 9 by aviation police after he refused to give up his seat on the fully booked plane to make room for crew members.

He suffered concussion, a broken nose and lost two front teeth.

When asked if the United had ever made an offer for a possible settlement, Demetrio replied, "No, that's not happening right now."

He said that his client was "taken off that flight like a sack of potatoes."

Demetrio also confirmed that he will represent a woman passenger with two babies, who clashed on board with an American Airlines flight attendant. The incident has already gone viral over social media and drew wide uproar.

The woman could not hold her tears when the male attendant confronted her and other passengers over a baby stroller problem, as the online video shows.
