Determinants of air travel demand: The role of low-cost carriers, ethnic links and aviation-dependent employment

This paper presents a comprehensive gravity model in which the most important determinants for air travel demand have been identified using a two-stage least squares technique. Besides including the standard demand factors like GDP, population and tourism, the effects of other determinants such as domestic traffic, low-cost carrier (LCC) activity and public service obligations are also estimated. The profound contribution of the paper lies in the inclusion of two innovative variables in the estimations: ethnic links and aviation-dependent employment. The econometric results show that both ethnic links between countries and the share of aviation-dependent employment increase passenger demand. Moreover, the results confirm that LCC presence leads to a significant increase in passenger demand, particularly on routes where Europe’s largest LCCs, Ryanair and easyJet, are active.
