We extend the monopoly case without congestion in Brueckner (2004) by examining network choice in a duopoly where airport congestion can occur. Airlines prefer hub-and-spoke configurations, even if this implies higher congestion costs. Airlines may be inefficiently biased towards hub-and-spoke...

This paper explores, both theoretically and empirically, the impact of granting antitrust immunity (ATI) to airline alliances in a novel and realistic framework characterized by vertically-differentiated air services. Our theoretical model suggests that non-ATI alliances produce an up-market...

Convenient scheduling, characterized by adequate flight frequency, is the main quality attribute for airline services. However, the effect of airline alliances on this important dimension of service quality has received almost no attention in the literature. This paper fills this gap by...

Scheduling coordination is said to be both a reason for and a consequence of airline consolidation. This paper offers a first attempt to formally model this dimension of airline partnerships, in a simple setup of complementary alliance with schedule delay affecting the passengers' utility. We...

As low-cost airlines or carriers excluded from international markets by regulation may seek to expand internationally in an indirect way through code-sharing agreements, they can choose partner airlines from among domestic or international carriers. The former case results in a...

This paper offers a first model of parallel frequent flier programs partnerships, rather typical for the US domestic market. We model these partnerships as arrangements which make carriers' services more substitutable, in a setup where consumers value frequency and exhibit varying degrees of...

In a hub-and-spoke network, the total profit function of an airline is supermodular with respect to its entry decisions at different city-pairs. This source of complementarity implies that a hub-and-spoke network can be an effective strategy to deter entry of competitors. This paper presents a...
