Mahan Air to Suspend Türkiye Flights September 21

The suspension also covers Mahan Air’s flights to Balikesir, in addition to services to Istanbul and Ankara.
The U.S. Treasury’s September 8 action designated 27 Iranian airlines and nine third-country intermediaries accused of helping carriers circumvent sanctions, obtain aircraft and spare parts, and transport cargo internationally.
U.S. Treasury Secretary Scott Bessent warned companies that continue doing business with the designated airlines that they could be excluded from the international financial system.
As part of the sanctions response, OFAC suspended General License J-1, which had permitted the temporary reexport of certain civil aircraft to Iran, and issued General License DD to allow the wind-down of previously authorized civil-aviation transactions.
OFAC also designated three Türkiye-registered companies for their links to Mahan Air, including Istanbul-based MES Cargo Transportation Tourism and Foreign Trade Limited Co.
Mahan Air will stop flying between Iran and Turkey starting September 21, 2026, following orders from Turkish aviation authorities. Middle East Eye reported the suspension covers routes to Istanbul, Ankara, and Balikesir. The decision comes just two weeks after the U.S. Treasury sanctioned 27 Iranian airlines and nine foreign companies helping them dodge restrictions on aircraft and spare parts.
The Iranian carrier has already announced suspensions to Oman and Georgia, as U.S. sanctions tighten the screws on its international operations. The New York Times noted the moves are deepening Iran's isolation at a critical time. Treasury Secretary Scott Bessent warned that any company continuing to work with the sanctioned airlines risks being cut off from the global financial system.
Turkish authorities banned Mahan Air after the U.S. Treasury's September 8 sanctions targeting three Turkey-based companies linked to the airline. Middle East Eye reported that Istanbul-based MES Cargo Transportation was among those designated for supporting Mahan Air's ground operations. Turkey faced pressure: continue serving Mahan Air and risk sanctions itself, or suspend flights and comply with U.S. restrictions.
The final Tehran–Istanbul and Tehran–Ankara flights depart September 20. Other airlines will continue serving these routes, but Mahan Air's suspension is indefinite. Financial Times noted Mahan Air is one of Iran's largest and most popular carriers, making the suspension a significant blow to the country's aviation network.
On September 8, the U.S. Treasury designated 27 Iranian airlines and nine third-party intermediaries under what the U.S. calls Operation Economic Outcast. Streamline Feed reported the action targets companies accused of helping Iranian carriers obtain aircraft, spare parts, and transport services. The sanctions also suspended General License J-1, which previously allowed temporary reexports of civil aircraft to Iran.
Treasury Secretary Bessent made the stakes crystal clear: "Companies doing business with these designated airlines face exclusion from the U.S. financial system." The message is simple—work with sanctioned Iranian carriers and lose access to global banking and trade networks.
Mahan Air has faced U.S. sanctions since 2011 over alleged ties to Iran's Islamic Revolutionary Guard Corps and its Quds Force. The September sanctions represent the latest escalation in a 15-year campaign to isolate the airline from global commerce. Mixvale reported the suspensions extend beyond Turkey, with routes to Oman and Georgia also cut as pressure mounts.
Each sanction wave narrows Mahan Air's options—fewer routes, fewer partners, fewer planes. The Turkey suspension signals that even neighboring countries are willing to distance themselves from Iran's aviation sector rather than risk U.S. retaliation. For Iranian travelers, the route closures mean fewer international connections at a time when Iran's economy is already under strain.
