Since the availability of slots is directly connected to the capacity of an airport at a particular date and time, a slot is by definition a scarce resource. The extent of. Slot scarcity depends on the congestion level of an airport. Excess demand for slots has substantial implications for airlines, coordinators and airports alike, as well as for society as a whole. This dissertation is designed to explore the compatibility of the global and specific legal regimes governing airport slot coordination with the particular socio-economic challenges that international organizations, governments and air transport industry stakeholders are experiencing today. A multitude of socio-economic objectives are identified, including but not limited to the environment in terms of noise and carbon reduction policies, growing airport access issues and general debates on airport functions to society.
