Xining Caojiabao, Nanjing Lukou Intl, and Chongqing Jiangbei Intl are the top three LongJiang Airlines airports based on our airline data. This may change if LongJiang Airlines makes updates to their flight routes due to supply and demand.
LongJiang Airlines does not have flights from Singapore Changi at the moment. There are scheduled flights with LongJiang Airlines out of Sanya Phoenix Intl though (if you don’t mind flying from this airport). Flying with Sichuan Airlines is recommended if you still want to fly from Singapore Changi.
