Iran Implements Temporary Airspace Restrictions in Western Region, Affecting Flight Operations

Temporary Airspace Measures Enacted in Western Iran

Aviation authorities have implemented provisional flight restrictions covering specific portions of Iranian airspace. The Notice to Airmen (NOTAM) primarily affects the western sector of the Tehran Flight Information Region, effective from May 22 to May 25, 2026.

Operational Guidelines for Designated Airports

During this period, only eight airports in the western region will remain partially operational:

• Commercial flights are permitted solely between sunrise and sunset
• Tabriz International Airport and Mehrabad International Airport are among the facilities remaining open
• All other western airports will temporarily suspend commercial flight operations

Requirements and Recommendations for Airlines

All carriers operating within or transiting through Iranian airspace must adhere to the following:

• Explicit authorization from Iran's civil aviation regulator is mandatory prior to flight
• It is advisable to contact relevant authorities well in advance and submit flight plans
• Consider adjusting flight routes or schedules to comply with daylight operating windows

These temporary restrictions are likely to impact international flight path planning through the region. Airlines are encouraged to monitor NOTAM updates closely for any changes.
