1. A method for determining an estimated origin-destination service product unconstrained demand, comprising the steps of:
- retrieving a segment level unconstrained demand forecast for each flight segment within an origin-destination pair, wherein the flight segment comprises a segment having a single take-off and a single landing for an aircraft;
generating with a computer processor a consumer preference for origin-destination service products;
generating with the computer processor a network flight schedule by determining which available service products use one of the flight segments based on the segment level unconstrained demand forecast and the consumer preference for origin-destination service products, wherein the network flight schedule comprises a determination whether a service product uses a particular flight segment;
retrieving a historical origin-destination pair demand;
receiving a historical demand adjustment factor, wherein the historical demand adjustment factor is greater than 1 if a historical demand level is given greater weight than the segment level unconstrained demand forecast;
determining an estimated origin-destination unconstrained demand based on the segment level unconstrained demand forecast, the historical origin-destination pair demand, the network flight schedule, the consumer preference for origin-destination service products within the origin-destination pair, and the historical demand adjustment factor; and
computing the estimated origin-destination service product unconstrained demand based on the estimated origin-destination unconstrained demand and the consumer preference for origin-destination service products.

Abstract
An airline origin-destination revenue management software system supports decisions to accept or deny request for booking on airline seats by comparing the fare for the request with a minimum acceptable fare predetermined by the system. In order to determine the minimum acceptable fare, the system typically solves an optimization problem that takes as input the airline'"'"'s flight network schedule, fares and forecasted passenger demands for all products available for booking on the airline'"'"'s flight network, and available capacity on each of the airline'"'"'s scheduled flights.
