This review begins with an introduction to the
functions of typical airline RM systems, followed by
descriptions of the types of OR models employed to
perform three of the principal techniques of revenue
management—overbooking, fare class mix, and O-D
control. Therefore, the focus of this discussion is on
the seat inventory control component of airline revenue maximization, as virtually all airline RM systems
assume that the fare structure is determined exogenously by a separate airline pricing function.
