Scott Bessent, a key figure in the current US administration's economic policy, has signaled an intent to expand sanctions against Iran by targeting its aviation sector. The proposed strategy aims to effectively ground all Iranian airlines on a global scale. This approach represents a significant escalation in economic pressure, moving beyond direct sanctions on the carriers themselves.

The scope of the threat includes a wide array of support services essential for international air travel. According to reports, the US is looking to penalize airports, ticketing agencies, fuel suppliers, and maintenance providers that facilitate the operations of Iranian airlines outside of Iran. By targeting these secondary businesses, the US aims to create a logistical environment where Iranian aircraft cannot legally or practically operate in foreign territories.

While the administration frames this as a necessary tool in its broader foreign policy, the move would likely disrupt international travel and logistics networks involving Iran. The proposal highlights a shift toward 'secondary sanctions'—penalizing third-party entities in other countries for doing business with Iranian aviation firms. As of now, the specific timeline for the implementation of these measures or the legal mechanisms to enforce them globally remains under development. The move is part of a larger effort to isolate Iran's economy, though the practical challenges of enforcing such a wide-reaching ban on international support services remain a point of discussion among global aviation authorities.
