We work with an itinerary-based airline fleet assignment model where an itinerary choice model is explicitly integrated. The choice model represents the decision on pricing as well as the spill and recapture effects. We present a sensitivity analysis for the key assumptions of the demand model in order to quantify the added value of the choice-based fleet assignment. The model is solved with a local search heuristic which iterates over two sub-problems. We present a set of reformulations as a convexification of the revenue sub-problem which is expected to increase the efficiency of the solution methodologies.
