We have developed a Global Airport Connectivity Index (GACI), which measures each airport’s relative importance in the air transport network, by combing the five selected centrality indicators , which are degree centrality, flow betweenness, closeness centrality, eigenvector centrality, and regional importance, into a single score. It helps identify and assess dominant airports as to where they rank in relation to their counterparts, upon changes of network topology and passenger flows through the network over time.
The below table shows the top-55 airports (with GACI ≥ 2.0) in 2016, and their GACI and rank changes since 2006.
| Airport (ranked by 2016 GACI) |
