The Evolution of United Airlines
United Airlines traces its roots back to 1926, making it one of the oldest airlines in the United States. The company began as Varney Air Lines before merging with Boeing Air Transport to form United Air Lines in 1931.
Over the decades, United has grown through strategic acquisitions and expansions. Key milestones include the 1961 merger with Capital Airlines, which significantly expanded their East Coast presence, and the 2010 merger with Continental Airlines that created the world’s largest airline at the time.
Today, United operates as a major component of the Star Alliance network, providing passengers access to over 1,300 destinations worldwide through partnerships with other member airlines.
