US sanctions 27 Iranian airlines, reveals how three Boeing 777s reached Mahan Air

On September 8, 2026, the US Department of the Treasury imposed sanctions on 36 targets within Iran’s aviation sector. This action specifically targeted 27 Iranian airlines and included measures against entities involved in supporting these companies. The sanctions were implemented as part of ongoing efforts to counter Iran's revenue streams related to its aerospace industry. Investigations revealed that three Boeing 777 aircraft ultimately operated by Mahan Air utilized routes facilitated by sanctioned parties. These actions demonstrate a continued commitment from the United States to disrupt financial networks enabling support for Iranian aviation operations.
