In airline schedule planning models, the demand and price information are usually taken as inputs to the model. Therefore schedule and capacity decisions are taken separately from pricing decisions. In this paper we present an integrated scheduling, fleeting and pricing model for a single airline where these decisions are taken simultaneously. This integration enables to explicitly model supply and demand interactions and take superior decisions. The model refers to a monopolized market. However, competing airlines are included in the model as a reference for the pricing decisions. The schedule planning model consists of schedule design and fleet assignment models. The pricing decision is formulated through an itinerary choice model which determines the demand of the alternative itineraries in the same market according to their price, travel time, number of stops, and the departure time of the day. The demand model is estimated based on real data and is developed separately for economy and business classes. The seat allocation for these classes are optimized according to the behavior of the demand. The choice model is also used to appropriately model the spill and recapture effects. The resulting model is evaluated with different illustrations and the added value of the integrated approach is analyzed compared to a sequential approach. Results over a set of representative instances show that the integrated model is able to take superior decisions by jointly adjusting capacity and pricing.
