Air China Limited (simplified Chinese: 中国国际航空公司; traditional Chinese: 中國國際航空公司; literally: "China International Airlines Company", colloquially known as 国航/國航, : 0753, : , : ) is the flag carrier and one of the major airlines of the People's Republic of China, with its headquarters in Shunyi District, Beijing. Air China's flight operations are based at Beijing Capital International Airport. In 2015, the airline carried 90 million domestic and international passengers with an average load factor of 80%.

Air China was established and commenced operations on 1 July 1988 as a result of the Chinese government's decision in late 1987 to split the operating divisions of Civil Aviation Administration of China (CAAC) into six separate airlines: Air China, China Eastern, China Southern, China Northern, China Southwest, and China Northwest. Air China was given chief responsibility for intercontinental flights and took over the CAAC's long haul aircraft (Boeing 747s, 767s, and 707s) and routes.

In January 2001, the former CAAC's ten airlines agreed on a merger plan, according to which Air China was to acquire China Southwest Airlines. Before the acquisition, Air China was the country's fourth largest domestic airline. The merger created a group with assets of 56 billion Yuan (USD $8.63 billion), and a fleet of 118 aircraft. In October 2002, Air China consolidated with the China National Aviation Holding and China Southwest Airlines.
