The senators said the incident could have been prevented with better communication or "additional incentives" - an apparent suggestion that United didn't offer passengers enough compensation to voluntarily give up their seats.
Officers with the Los Angeles Airport Police do not get involved in civil matters such as business disputes between airlines and passengers. She also wrote a letter to United Airlines CEO Oscar Munoz to raise concerns over the violent incident. "To remove a booked, paid, seated passenger". 'We can't do that'.
A spokesperson said all those on Flight 3411 on Sunday night from Chicago to Kentucky would be "receiving compensation for the cost of their tickets", according to reports from USA media. Passengers can choose to receive a refund, a travel voucher or frequent flyer mile payout equal to the full price of their ticket, ABC News has learned.
"That absolutely would have been me", he told Inside Edition as he watched the video of Dr. David Dao being dragged down the aisle of the United plane during Sunday's flight from Chicago to Louisville.
"It was a system failure", Munoz said. "We have not provided our frontline supervisors and managers and individuals with the proper procedures that would allow them to use their common sense".
A viral video of police officers dragging a passenger from a United Airlines flight left the country aghast Monday, so much so that even the likes of Jimmy Kimmel felt the need to weigh in.
Dao's attorneys Wednesday filed papers asking the Cook County court to preserve reports and other material related to Sunday's incident.
In a news release, the attorneys said they plan to talk to the media and that they will be accompanied by a relative of Dao.
Dao and his wife initially agreed to get off the plane, passenger Jayse Anspach said.
Munoz apologized on Tuesday, calling the episode "truly horrific", and pledged a full review by April 30.
Newly surfaced video shows the heated back and forth that transpired between Dao and the officers when he was informed he'd been selected to forfeit his seat to United crew members. Dao only started to get mildly upset when the second officer came on the plane after he continued to refuse to leave.
For Chicago, it is another public relations nightmare following a crime wave in parts of the city that has been highlighted by tweets from President Donald Trump. No one volunteered. United chose to select people at random.
United Airlines issued three statements on the incident, at first suggesting Dr Dao was partly responsible and labelling him "disruptive and belligerent" in a leaked email. The flight crew then called for airport police to remove him.
In the ABC interview, Munoz apologised profusely to Dao, his family, passengers and United customers.
