Tensions between Iran and the United States, along with related regional dynamics involving Israel, remain the central driver behind expectations for another airspace closure. Iranian authorities briefly shut most commercial routes in January 2026 amid heightened alerts over potential strikes, then imposed a longer partial closure through early April before partially reopening eastern corridors and limited airport operations on April 21. Commercial flights from Tehran resumed in early May under conditions of cautious normalcy, yet airlines continue routing around Iranian airspace due to lingering security concerns. Upcoming diplomatic signals, military posture changes, or escalation in proxy conflicts could trigger renewed restrictions within the coming weeks, particularly around key dates such as May 31.
