According to Globeair.com, there are three key features of an international airport which are; Customs and Immigration Facilities, International Flight Operations, and Global Connectivity.
An airport has the “international” tag when it has the designated facilities and infrastructure to manage customs, immigration, and quarantine procedures for inbound and outbound passengers and cargo.
Analysts have made a connection between airports and regional development based on the associations between airport passengers, population, and employment growth.
