Since June 2012 China Southern has marketed the Canton Route, a way of travelling between Europe and Australia or New Zealand with one stop in Guangzhou. The first link was Guangzhou to London Heathrow. It competes with the traditional Kangaroo Route via Southeast Asia or the Gulf. Check China's transit visa rules for your nationality before booking a connection through Guangzhou.
China Southern was set up on 1 July 1988 when China's civil aviation authority was split into separate airlines. It began flying under its own name and colours in February 1991 and became independent of the authority in October 1993. It is owned by China Southern Air Holding, a state enterprise, and its shares trade in Shanghai and Hong Kong.
The airline was the only mainland Chinese operator of the Airbus A380 and flew its last commercial A380 flight on 5 November 2022.
China Southern joined SkyTeam on 15 November 2007, becoming the first mainland Chinese airline in an alliance, and left on 1 January 2019. Since then it has relied on bilateral partners. A frequent flyer partnership with American Airlines started in March 2019, and the airline works with Qantas, Emirates, Qatar Airways, and Air France and KLM through a joint venture.
China Southern holds 55 percent of XiamenAir, 60 percent of Chongqing Airlines and 39 percent of Sichuan Airlines, and owns Xiongan Airlines and the maintenance company GAMECO. China Southern Cargo runs freighters from Shanghai and Guangzhou.
