"As I think about our business and our people, the first thing I think is important to say is to apologize to Dr. Dao, his family, the passengers on that flight, our customers, our employees".
Munoz apologized on Tuesday, calling the episode "truly horrific", and pledged a full review by April 30.
A log of the incident available to staff and obtained by Mail Online appears to show the airline claim that 69-year-old grandfather David Dao "attempted to strike law enforcement". The Associated Press also confirmed that Dao is the man in the video.
"The family of Dr. Dao wants the world to know that they are very appreciative of the outpouring of prayers, concern and support they have received", the statement reads.
The US Department of Transportation has said that it is reviewing Sunday's events to see if United violated rules on overselling flights.
"I have students of mine who are crying", he said.
"I share all of those sentiments, and above all: my deepest apologies for what happened". And you saw us at a bad moment.
Too disturbed by what he had witnessed, Powell said he grabbed his students and walked off the plane. "I was hired to make United better and we've been doing that and that's what I'll continue to do". "Right now you never know if you'll be dragged off the plane after booking a flight", a passenger named Josh Blaha said in his comment Tuesday.
"That shame and embarrassment was pretty palpable for me and for a lot of our family", the contrite chief executive told ABC's Good Morning America programme.
Meanwhile, someone on social media modified the logo of Southwest Airlines to have a dig aimed at United, which has been at the centre of a media storm since the incident occurred.
Spicer says he's sure Trump has seen the video but that any comment from the president could influence a potential outcome of the investigations. In most cases, passengers who are bumped from the flight because of overbooking or other reasons are informed at the gate, before they have boarded the plane.
The event stemmed from a common air travel issue - a full flight. Munoz said in a letter to employees that the airline offered $1,000. The airline offered $800 for passengers to give up their seats, but none of them took the offer. United has not said precisely how the four people asked to leave Flight 3411 were selected. He refused to leave.
A total of three Chicago Department of Aviation officers are on leave following the incident, which has turned into a publicity nightmare for United.
It's an often-overlooked policy to which you agree when you book your tickets.
"We're not going to put a law enforcement official to take them off", he said. "We were stuck there".
