David Carter, an associate professor of finance at Oklahoma State, has an interesting perspective on why rivals haven’t caught up to Southwest. Prof. Carter helped write a 2004 case study on Southwest’s hedging that is taught in business schools. Although the study details how Southwest uses home-heating-oil futures and other instruments to make its hedges work, Prof. Carter says he has heard from only one other airline that seemed interested in putting that knowledge to work: the German carrier Lufthansa.
Other carriers may have opted for caution because it is psychologically hard to switch strategies when prices are moving against you, Prof. Carter says. Airlines that didn’t hedge much when oil was at $25 or $40 a barrel might have felt uncomfortable launching a big hedging program when oil got above $60.
Frequent management shuffles at many airlines also might have made it harder for carriers other than Southwest to jump into hedging in a big way, Prof. Carter adds. A hedging blunder early in a CEO’s tenure might overshadow whatever else that boss might be accomplishing.
Southwest’s treasurer, Scott Topping, offers another possible explanation of why his airline has stayed ahead of the pack so long: Since the late 1990s, Southwest’s hedging strategy has been set by two or three people, rather than by committee, making it easier to act decisively.
