Iran’s formal airspace remains open to limited domestic and authorized operations, yet international carriers continue to avoid the Tehran Flight Information Region due to persistent missile, drone, and air-defense risks tied to the unresolved US-Israel-Iran conflict that began with strikes on 28 February 2026. European and US regulators have extended avoidance advisories through mid-November 2026, citing high-alert Iranian postures and potential misidentification hazards, while recent NOTAMs for live-fire exercises near the Strait of Hormuz and elevated GPS interference reinforce caution. Neighboring states have imposed temporary restrictions amid regional military movements, and Iranian statements on conditional reopening or reciprocal flight limits add uncertainty. Trader assessments reflect these ongoing security assessments and scheduled regulatory reviews rather than any confirmed blanket closure.
