The document discusses integrating customer relationship management (CRM) and revenue management (RM) in passenger airlines. It notes that while CRM aims to facilitate lifetime loyalty through repeat business, RM aims to optimize short-term revenues and profits. This can create conflicting objectives between CRM, which focuses on individual customers long-term, and RM, which focuses on market segments and transactions. The document proposes developing customer relationship revenue management (CRRM) to better align CRM and RM by personalizing offers and availability based on individual customer value and preferences. This could help address conflicts between loyalty programs and RM practices.
