Title: An Integrated Approach to Single-Leg Airline Revenue Management: The Role of Robust Optimization Authors: Ilker Birbil Faculty of Engineering and Natural Sciences Sabanci University Istanbul Turkey.

These robust models take into account the inaccurate estimates of the underlying probability distributions. As observed by simulation experiments it turns out that for these robust versions the variability compared to their classical counter parts is considerably reduced with a negligible decrease of average revenue.
