One Chicago Aviation security officer involved is now on paid leave. CDA said it will not release the names of the officers.
Dao, who was discharged from the hospital on Wednesday night, suffered a significant concussion, a broken nose and lost two front teeth in the incident, and he will need to undergo reconstructive surgery, Demetrio said.
Munoz was asked about calls for his resignation as leader of the embattled airline on the ABC show "Good Morning America" following widespread outrage at the company's actions in the incident on Sunday. Various versions of the video have been viewed more than 1 million times on YouTube by last count.
John Slater, a United vice president, said that bumping passengers to accommodate airline employees happens infrequently, and that federal guidelines requiring rest for crew members made it necessary to get the employees on the Sunday flight to Louisville. "My initial words fell short of truly expressing what we were feeling. And that's something that I've learned from".
Munoz called the embarrassment a "system failure", saying United will review its policies for seeking volunteers to give up their seats when a flight is full. "No one should ever be mistreated this way", he 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".
Demetrio said the law stated that passengers could not be ejected from planes with unreasonable force.
Generally there are enough empty seats or volunteers to make up for overbooking situations.
The practice lets airlines keep fares low while managing the rate of no-shows on any particular route, said Vaughn Jennings, spokesman for Airlines for America, which represents most of the big US carriers. The attorneys also want United's protocol for removing passengers from commercial aircraft. Some people are getting a refund, others a travel voucher and still others air miles, depending on what they tell the airline they want. United customers at O'Hare reacted Wednesday to the promised changes.
That's when three Aviation Department police officers boarded the plane.
Banning overbooking would reduce load factor, and airlines would try to compensate, said Philip Baggaley, senior airlines credit analyst for Standard & Poor's.
The man told an airport employee that the giant document was his boarding pass, and she replied: "That is absolutely fantastic".
Many flyers are now urging a boycott of the carrier and some protested the airline's response by ridding themselves of the company reward scheme and other perks.
Meanwhile Wednesday, there was more criticism of United Airlines on the grounds of its medical preparedness.
Paul Callan, a civil and criminal trial lawyer in NY, said the public outcry over Dao's treatment would likely push the airline to a quick and generous settlement.style="text-align: center;"
