英文摘要：

Loyalty program partnership as an important relationship marketing instrument has become one of the hotspots in marketing research. However, the key as to whether a firm will join the loyalty program partnership and how to choose the core enterprise lies in how to reinforce the expected effects and to achieve the multi-win. In view of the fact that domestic airlines have joined the international airline alliances one after another, this paper chooses China Southern airlines as an example, and uses single case study, including interviews and secondary data collection. It is concluded that： （1）The motive of China airlines joining the airline alliances is the fierce competition in the aviation market. Their management and service level must be improved. （2）China airlines＇ selection of alliances is mainly based on the complementarity among routes and the mutual cooperation before joining. （3）China airlines rapidly expand international and domestic markets, reduce costs and increase revenues and in the meanwhile, the management level and service level rise substantially.
