"The incident has been a humbling learning experience for all of us here at United", he said.
After the controversial decision to forcibly remove a boarded passenger from Flight 3511, United Airlines has changed their policy with respect to overbooked flights.
Several passengers on United flight 3411 from Chicago O'Hare International Airport to Louisville, Kentucky, captured video as a man was dragged off the plane by authorities after he apparently refused to leave from an overbooked flight.
The CEO took personal responsibility for the incident, which drew widespread condemnation, and said no employees would be fired as a result of it. Munoz confirmed that he would remain in his position amid public calls for his resignation. In an email to United personnel, he labeled Dao "disruptive and belligerent" and insisted: "I emphatically stand behind all of you".
Blumental recently penned a letter to US Transportation Secretary Elaine Chao - whose department is reportedly reviewing the United Airlines incident - outlining his concerns with the treatment of passengers by US airlines.
The parent company of the third-largest commercial airline in the United States reported earnings of 41 cents per share, up from analysts' forecast of 38 cents, and revenues were up 2.7 per cent to $8.4billion.
Munoz said Tuesday he spoke with the local Chinese consulate and will be traveling to China on a previously scheduled trip.
But he added: "There was never a consideration for firing an employee".
He described the incident as a "system failure across various areas".

And some USA politicians have called for a total ban on overselling flights. Munoz declined to address that or other possible changes until the airline finishes a review by April 30. "It's really too early for us to tell anything about bookings, and in particular last week because it's the week before Easter".
The House panel did not say who it plans to call as witnesses or what prompted the oversight hearing.
Dao emigrated to the US from Vietnam.
"We are looking at a broad array of issues", Munoz said.
He sang a markedly different tune in the days after the incident, apologizing publicly to Dao and telling "Good Morning America" on Wednesday the airline would no longer allow police to haul paying customers off its flights.
