The effects of global alliances on international flight frequencies: Some evidence from Italy

We collect half-yearly data on nonstop flight frequencies offered by carriers on routes originating from Italian regions to European countries in the period 1998-2010. We find that, as the share of flights belonging to global alliances increases, the number of flights offered by airlines simultaneously expands, especially in the case of full-service carriers. Moreover, there is also evidence that the number of global alliances has a positive impact on flight supply. © 2014.
