Iranian Carrier’s Aircraft Seized in Istanbul Amid U.S. Sanctions

Seizure at Istanbul Airport
On Monday, court-ordered enforcement officers detained a Caspian Airlines Boeing 737 at Istanbul Airport before it could depart for Iran. The aircraft, registered EP-KPB, was seized after lawyers for the creditor—aviation representation and supervision firm ACM Temsil Gözetim—served a debt claim of roughly €3 million. Passengers and cabin crew were escorted off the plane and held in the terminal while the aircraft was taken into custody.
U.S. Secondary Sanctions on Iranian Aviation
The seizure follows the United States Treasury’s secondary-sanctions regime launched on 8 September, which placed 27 Iranian airlines and nine related service providers on a blacklist under Operation Economic Outcast. The Treasury warned that foreign airports, fuel suppliers, ground handlers, and ticketing firms that continued to service the listed carriers could themselves face sanctions and loss of access to the U.S. dollar system.
Ripple Effects on Iranian Airlines
The secondary sanctions triggered a rapid contraction of Iran’s international air links. Flights by Iranian carriers were suspended in Iraq, the United Arab Emirates, Azerbaijan and Oman. Iran’s largest private airline, Mahan Air, halted services to Turkey and Oman, while Lufthansa and Austrian Airlines announced suspensions of their routes to Iran through 24 October. Qatar Airways also suspended service, citing airspace restrictions. Tracking data show daily international departures from Tehran’s main airport fell from 80-90 to about 41 by the Monday of the seizure.
Official Reactions
Iran has lodged formal complaints with the United Nations, the International Civil Aviation Organisation, and the International Court of Justice, arguing that the sanctions and related enforcement actions violate international aviation norms. Turkey, however, has not formally barred Iranian carriers, which is why Caspian Airlines remained scheduled on the Istanbul-Tehran route at the time of the seizure.
Upcoming Restrictions
Lufthansa and Austrian Airlines’ suspensions of Iranian routes are set to remain in effect until 24 October, extending the limited connectivity for Iranian passengers and further pressuring the country’s already strained aviation sector.
