Ilam Airport — Ilam, Iran

IIL is Ilam Airport, serving the city of Ilam in western Iran near the border with Iraq, in the mountainous Ilam province. The airport provides domestic connectivity for this relatively remote western region, linking it to Tehran and reducing dependence on long overland routes through the Zagros Mountains. Ilam province is historically significant as part of the ancient Elamite civilization's territory, though the airport itself is a modern, modest facility built to serve contemporary administrative, commercial, and limited tourism needs of the provincial capital. IIL handles a relatively low volume of scheduled flights compared to Iran's major hub airports, consistent with the province's smaller population.
