CAAC Airlines (Chinese: ????), formerly the People's Aviation Company of China (????????), was the airline division of the Civil Aviation Administration of China (CAAC) and the monopoly civil airline in the People's Republic of China. It was founded on July 17, 1952, and merged into CAAC on June 9, 1953. In 1988, the monopoly was broken up and CAAC Airlines was split into six regional airlines, which later consolidated into China's Big Three airlines: Beijing-based Air China, Guangzhou-based China Southern Airlines, and Shanghai-based China Eastern Airlines.

Seperation

In 1988, CAAC Airlines split into six separate airlines, each named after the geographic region of their main operating areas:

Air China, the flag carrier, based in Beijing, inherited the IATA and ICAO code of CAAC
China Southwest Airlines, based in Chengdu (merged into Air China in 2002)
China Eastern Airlines, based in Shanghai
China Northwest Airlines, based in Xi'an (merged into China Eastern in 2002)
China Southern Airlines, based in Guangzhou
China Northern Airlines, based in Shenyang (merged into China Southern in 2003)
CAAC used the IATA code CA on international flights only; domestic flights were not prefixed with the airline code.

CAAC's aircraft livery featured the Chinese national flag on the vertical stabilizer, with blue stripes and Chinese version of CAAC logo (designed by Lu Shifang in 1965,[3] with the calligraphy of Premier Zhou Enlai) on a white fuselage.
