West Air China, also known as West China Airlines, is a regional Chinese carrier operating under IATA code PN and ICAO code CHB with the callsign WEST CHINA. Founded in the early 2000s, the airline is headquartered in Chongqing and primarily serves domestic routes within China, with a focus on connecting western and central regions of the country. The airline operates a fleet of narrow-body aircraft and has grown steadily to serve numerous secondary and tertiary cities across China. It plays an important role in improving air connectivity in less-served western Chinese provinces. West Air China is a subsidiary of HNA Group, one of China's largest aviation conglomerates, which has given it access to broader resources and route networks within the Chinese domestic aviation market.
