American Airlines is a widely cited leader in the development and implementation of yield management practices. This case is based on a training exercise used at American Airlines to introduce managers to their yield management system. Participants are given the responsibility for a single flight from Dallas-Fort Worth, Texas to Miami, Florida and are required to make a series of sequential booking decisions in real time. The objective of the exercise is to maximize total revenue for the flight, after taking into account no-shows and penalties. De-briefing following the exercise provides an opportunity to discuss both the strategic and tactical issues that arise when applying yield management systems in service firms. The case is designed for use in a service management elective course or in a service operations course and is intended to expose students to yield management by giving them hands-on experience managing bookings for a flight. The game takes approximately 50 minutes to play, leaving approximately 30 minutes for class discussion. Ideally, a supplemental reading dealing with yield management should be assigned with the case in order to provide background theory on yield management and to describe the complexities of a yield management system.
