Zahedan International Airport matters in the Hormuz Graph as the main aviation access layer for Iran’s southeastern border province, where long distances, dispersed settlements, Pakistan-facing trade, Afghanistan-facing routes, and Chabahar corridor planning make mobility unusually important. Its role connects provincial administration, business travel, security-sensitive operations, logistics coordination, and access to Zahedan’s road and rail network. The asset is relevant because companies evaluating southeast Iran need practical movement for managers, technical teams, inspectors, and partners across a region where road-only access can be slow and operationally complex.
