Iranian airspace remains severely restricted, with the Tehran FIR (OIIX) largely closed to civilian overflights since U.S. and Israeli strikes began on February 28, 2026, triggering emergency NOTAMs amid the ongoing conflict. Partial reopening of eastern sectors above FL285 occurred in late April following a fragile ceasefire, but western areas stay off-limits due to military risks, as confirmed by aviation authorities and U.S. embassy alerts. Trader sentiment reflects this tense status quo, driven by recent Iranian deployment of 10,000 FPV drones reported May 11 and Netanyahu's covert UAE visit on May 13 signaling Gulf-Israel defense coordination against Tehran. No major closures in the past 30 days, but escalation risks from port blockades, failed peace talks, or retaliatory strikes loom ahead of any full normalization.

A “major closure” is defined as a broad closure, cancellation, or suspension of commercial flights transiting, arriving in, and departing from Iranian airspace or a major Iranian Airspace region. A qualifying closure must apply generally to flights across Iran or a major Iranian airspace region. Limited cancellations, delays, or other partial closures will not qualify. Limited exceptions to a broad closure, however, will not disqualify such a closure from counting (e.g. exceptions for certain flights pre-approved by the Iranian Civil Aviation Authority may be permitted).
Any non-weather complete suspension of commercial arrivals and departures affecting at least two of the following airports will qualify: Imam Khomeini International Airport (IKA), Mehrabad Airport (THR), Mashhad International Airport (MHD), Shiraz International Airport (SYZ), or Isfahan International Airport (IFN).
Qualifying previous examples include the January 2026 total closure of Iranian airspace except to international flights with express governmental permission (https://www.reuters.com/world/middle-east/iran-shuts-airspace-most-flights-flightradar24-says-2026-01-14/) and the April 2024 closure of Iran’s western airspace (https://www.reuters.com/world/middle-east/iranian-airports-cancel-flights-until-monday-morning-2024-04-14/). Non-qualifying examples include the January 27, 2026 partial closure of Iranian airspace around the Strait of Hormuz (https://www.aa.com.tr/en/middle-east/iran-issues-airspace-notice-for-military-drills-near-strait-of-hormuz/3812508) and the January 25 - April 25, 2026 VFR (Visual Flight Rules) flights suspension which did not broadly close commercial aviation in a qualifying region (https://www.intellinews.com/iran-suspends-general-aviation-and-vfr-flights-in-new-airspace-directive-421997/).
Warnings, No-Fly-Zones, or other flight restrictions imposed by airlines or countries other than Iran will not be sufficient for a “Yes” resolution.
Airspace closures which occur solely due to weather conditions will not qualify.
The primary resolution sources for this market will be official information from Iranian aviation authorities and a consensus of credible reporting.
