The Wall Street Journal - July 7, 2008
Column co-authored by Dr. Savelsbergh, the Schneider professor at the H. Milton Stewart School of Industrial and Systems Engineering: Why can't Internet retailers be more like airlines? Airlines have long known that business travelers will pay higher fares in return for maximum booking flexibility, and that leisure travelers are willing to give up some flexibility in order to pay less. Recognizing and balancing these differences helps the carriers fill their planes to capacity while bringing in significantly more revenue than they would if seats were sold on a first-come, first-served basis.
