We consider an empirical model of worldwide airline alliances that we apply to a large set of companies for the period 1995-2000. Using observations at the network level, we estimate a cost, capacity, and demand system that accounts for cross-price elasticities. Our contribution consists in evaluating airlines' strategical interactions through the window of firms' network interconnections. We consider networks coincidences and potential connections with all their rivals. The results allow us to classify all company pairs as either complements or substitutes. We shed light on the fact that many airlines involved in the same alliance are potential substitutes.
