The US Treasury Department’s Office of Foreign Assets Control (OFAC) designated multiple Iranian airlines on its Specially Designated Nationals and Blocked Persons List on September 8, 2026, targeting passenger air carriers that Washington says are being used to support military logistics for the Islamic Revolutionary Guard Corps.

The action falls under Executive Order 13902.

What the sanctions actually do

The designations hit several well-known Iranian carriers, including Iran Aseman Airlines and Mahan Air. US persons are now prohibited from engaging in any transactions with the listed entities, and foreign companies that provide material assistance to these airlines risk secondary sanctions.

Mahan Air has been under US sanctions since 2011 for allegedly providing logistical support to terrorist activities. Iran Aseman Airlines, which has operated since 1980, is a newer addition to the restricted list.
