[引言]代号共享(Code Sharing)是航空公司战略市场开拓和跨国联合的一种有效方式,近年来已被全世界大多数航空公司普遍采用。由于代号共享的国际应用只是近几年来的新事物,而且由于它的技术性强、种类繁多、变化较快,至今国际上还未见专门论述代号共享的综合性文献。作者根据收集的有关资料以及从事该项工作的实际经验,试图对代号共享初步进行系统的介绍。 [Introduction] Code Sharing is an effective way for airlines to develop strategic markets and cross-border alliances and has been adopted by most airlines in the world in recent years. As the international application of code sharing is only a new thing in recent years, and because of its technicality, variety and rapid change, so far there is no international comprehensive discussion of code-sharing literature. Based on the information collected and the practical experience of doing the work, the author attempts to give a systematic introduction to the code sharing.
