About China Southern Airlines
China Southern Airlines is based in Guangzhou, in southern China, and flies under the code CZ. Guangzhou Baiyun International Airport is its main hub, and it also has a large operation at Beijing Daxing. The airline was formerly a SkyTeam member but left that alliance, and today it does not belong to any of the three global alliances. Instead it works with individual partner airlines through codeshare agreements. Its network spans domestic China, Southeast Asia, Japan, Korea, South Asia, Australia and New Zealand, the Middle East, Europe and North America. Cabins include First, Business, Premium Economy and Economy, varying by aircraft.
China Southern Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Agents can search in the IATA.co booking portal, and developers can get the same live results from the flights API. Payment comes from your prepaid balance. Guangzhou is often used for connections between Australia and Europe, and whatever the itinerary, the fare rules are shown before you confirm.

Booking China Southern Airlines fares as a travel agent
Travel agents book China Southern Airlines fares on IATA.co without their own IATA accreditation.

China Southern Airlines results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
