Secretary Scott Bessent announced a global blockade of Iranian commercial aviation following the expiration of a 15 day license wind down. Any company or airport providing fuel, landing services, or ticket sales to Iranian carriers risks removal from the US dollar system. This pressure campaign, known as Operation Economic Outcast, coincides with tensions over the Strait of Hormuz and aims to isolate Tehran's civil aviation network.

Iraq is diverting Iranian Airways flights from Baghdad to Najaf airport, and services from Tehran to Baghdad and Muscat are canceled starting Wednesday midnight local time. Turkish Airlines, Pegasus, and AJet suspended flights until March 2027, while Chinese officials called the sanctions illegal and unauthorized by the UN Security Council. Iran stated that foreign flights by its airlines will continue starting in October.
