ABSTRACT
In countries outside of the US, the coordination of air movements at many airports occurs through the allocation of take-off and landing ‘slots’.1 The majority of large airports in both the European Union and the United States are hub airports and the IATA slot allocation process has relied generally on grandfather rights.2 The distribution of slots exhibits a similar pattern in these congested airports, with incumbent legacy carriers holding the lion’s share of air movements. Typically, the second largest competitor at a legacy carrier’s hub will have a (signicantly) smaller share of the total number of slots available.
