Abstract

This paper studies the evolution of global air transport network over the period 2006–2016. A Global Airport Connectivity Index (GACI) is proposed, combining degree, closeness and eigenvector topological indicators and two new volumetric indicators. We find faster passenger growth for larger airports that have improved in GACI. While America and North Asia focused on regional hub developments, serving short- to medium-haul routes, West Europe, South East Asia and Middle East focused on developing their major airports into global hubs. Our analysis shows that increasing GACI improves an airport’s competitive position and gives rise to increased influence over other airports.
