Iran's airspace has partially reopened as of April 19, 2026, following a phased restoration plan from the Iranian Civil Aviation Organization (CAO). The reopening is part of a fragile ceasefire, with Phase One allowing international transit flights through eastern air corridors such as Mashhad and Zahedan. However, the western and central airspace remains closed to most traffic, especially near high-risk areas bordering Iraq and the Persian Gulf. Tehran's Imam Khomeini and Mehrabad airports are operational but only allow limited international arrivals and departures with strict prior approval. Additionally, some airports are suspending operations between 9:00 PM and 5:00 AM due to operational limitations. Despite the reopening, commercial ticket sales are suspended, and major international airlines continue to avoid Iranian airspace due to safety concerns, opting for longer routes instead. The four-stage plan includes further phases aimed at gradually restoring air connectivity across the country.
