Iranian airspace remains partially open following a US-Iran ceasefire announced April 8 and extended amid uncertain implementation, with commercial flights resuming at Tehran's Imam Khomeini International Airport on May 1 after a 58-day halt due to US-Israeli airstrikes starting February 28. International carriers continue avoiding the region over risks from Houthi escalations and Strait of Hormuz tensions, but no full closure has been reported in the past 48 hours despite late-April warnings. Traders assess de-escalation signals against potential triggers like proxy attacks, diplomatic breakdowns, or ceasefire violations, with stability hinging on upcoming implementation reviews and military restraint before any May 31 deadline.

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.
