Imam Khomeini International Airport is a national-scale access asset in the Hormuz Graph because it is Tehran’s main international aviation gateway and a central interface between Iran, foreign business travel, air logistics, diaspora movement, and service-sector demand. Its role connects international passenger flows, business delegations, tourism, high-value cargo, airport services, and the capital-region economy. Unlike provincial airports, its value is systemic: it affects how foreign companies physically access Iran, how premium logistics enter Tehran, and how travel constraints shape market-entry execution.
