History and Background of United Airlines
United Airlines traces its roots to 1926 as Varney Air Lines, with the modern company formed in 1931 through mergers. It played a pioneering role in commercial aviation, introducing the Boeing 247 and expanding significantly post-World War II. Key milestones include the 1961 merger with Capital Airlines and the 2010 merger with Continental Airlines, which solidified its position as a major global player. Headquartered in Chicago, Illinois, United is a public company (NASDAQ: UAL) and a founding member of the Star Alliance.
As of 2026, United celebrates its centenary with a strong operational footprint, employing over 113,000 people and reporting robust financials in recent years.

The airline is heavily investing in its “United Next” program, adding hundreds of new aircraft (including 737 MAX, 787-9, A321neo, and A321XLR) through 2028.
