Oscar Munoz (born January 1959) is an American businessman. He was named president and chief executive officer (CEO) of United Airlines on September 8, 2015. At the time of this appointment, Munoz had been serving as a member of the board of directors of parent company United Continental Holdings (UCH) since its formation with the 2010 merger between United and Continental. Munoz had been a member of Continental's board of directors since 2004. On August 29, 2016, in a newly created role, United announced Scott Kirby as its president, with Muñoz being solely the CEO of the airline. 
On March 2017, Munoz was named "Communicator of the Year for 2017" by PRWeek. The following month Munoz received widespread criticism for his handling of the issues after a ticketed passenger was forcibly removed from United Airlines Flight 3411,leading Steve Barrett, Editor-in-chief of PRWeek US, to state "if PRWeek was choosing its Communicator of the Year now, we would not be awarding it to Oscar Munoz … In time, the episode and subsequent response will be quoted in textbooks as an example of how not to respond in a crisis." Subsequently, on April 21, 2017, UCH announced that Munoz would remain chief executive officer of the airlines but would "not take broader control of the company as previously planned." Munoz had been scheduled to assume the role of chairman of the board of UCH at the company's 2018 annual stockholders' meeting.
United Continental Holdings, Inc. (formerly UAL Corporation) is a publicly traded airline holding company headquartered in the Willis Tower in Chicago. UCH owns and operates United Airlines, Inc. The company is the successor of UAL Corporation, which agreed to change its name to United Continental Holdings in May 2010, when a merger agreement was reached between United and Continental Airlines. Its stock trades under the UAL symbol. To effect the merger, Continental shareholders received 1.05 shares of UAL stock for each Continental share, effectively meaning Continental was acquired by UAL Corporation; at the time of closing, it was estimated that United shareholders owned 55% of the merged entity and Continental shareholders owned 45%. The company or its subsidiary airlines also have several other subsidiaries. Once completely combined, United became the world's largest airline, as measured by revenue passenger miles.
