About Us

United Airlines, Inc. (often referred to as United) is a significant American airline with headquarters in Chicago, Illinois' Willis Tower. United Airlines has a significant domestic and international route network that connects major and minor locations across the United States as well as all six inhabited continents. It is the world's third-largest airline in terms of fleet size and route network.

United has eight hubs, the largest of which is Chicago–O'Hare, which carries the most passengers and has the most departures.

It is a founding member of the Star Alliance, the world's largest airline alliance with 28 members.

Independent carriers conduct regional service under the United Express brand. In the late 1920s, the United brand was formed by the merger of several airlines, the oldest of which was Varney Air Lines, which was founded in 1926 but was taken over by Continental Airlines management in 2010 in what was described as a "merger of equals" and a newly formed holding company for the airlines.
