China Southern Airlines (based out of Guangzhou) has officially announced that it has officially placed an order with Boeing for 12 Boeing 787-9s as the carrier is very pleased with the performance economics with the current 10 B788s that it already has in service.
The additional 12 B789s will be in due course used to replace their aging A330-200s from 2020 onwards as well as cater for expansion to Europe + North America from its upcoming Beijing hub base (the new international airport set to be opened in 2018).
