United Airlines now says it will require staff and crew to check in at least 60 minutes before a flight.
After a man was dragged off a United flight, the company changed its policy on overbooked flights.
The change comes after a passenger, Dr. David Dao, was dragged from a fully booked United Express flight at O'Hare Airport after he refused to give up his seat to make room for crew members trying to get to Louisville, Ky., where they had a flight to work.
During the removal, which grew into an embarrassing worldwide episode, Dao had two of his teeth knocked out, suffered a broken nose and a concussion and may require surgery, his lawyer said.
Last year, Delta got more passengers to give up their seats than any other US airline, partly by paying more.
United Airlines has reportedly been reviewing several of its policies after a video leaked six days ago of officers violently booting a passenger from one of its flights. Three of them have been placed on leave.
To say that United Airlines has not been having the greatest year would be a massive understatement.More news: 'Unsend' message feature, new shortcuts in test on WhatsApp
United said its new policy will ensure a crew member is seated before the plane is full.
Dao has yet to speak publicly on the matter but will when the time is right, said Demetrio, adding that a lawsuit against United is likely.
United Airlines found itself in the news again this week when a scorpion, which fell from overhead bin, stung a passenger. He also indicated that Dao will be suing the airline and the city of Chicago, which employs the airport police who dragged Dao down the aisle, his face bloody.
In the final statement, posted to the company's website on Thursday, United said the team expressed their "sincerest" apology to Dr Dao.
After Delta Air Lines made its announcement United Airlines stated that it was reviewing its compensation guidelines.
