Iran and Turkey Travel Disrupted as US Aviation Sanctions Squeeze Flights and Push Passengers Overland

Iran and Turkey travel connections are facing fresh disruption after tougher United States aviation sanctions placed 27 Iranian airlines under restrictions and increased the risks for companies providing services to sanctioned carriers. The pressure is affecting international flight operations and creating uncertainty around refuelling, airport handling, ticket sales and other aviation support. As air options narrow or become less predictable, travellers are increasingly looking towards land crossings into Turkey and Armenia to reach international flight hubs. The disruption is making regional journeys longer, more complicated and, in some cases, considerably more expensive.

US Measures Put 27 Iranian Airlines Under Sanctions

The latest pressure on Iran’s aviation industry stems from action announced by the U.S. Department of the Treasury on 8 September 2026.

The Treasury’s Office of Foreign Assets Control, or OFAC, designated 27 Iranian airlines under Executive Order 13902 for operating in Iran’s aviation sector. The wider action covered 36 targets connected with aviation.

The U.S. government said the measures were part of its Operation Economic Outcast campaign. Washington alleges that Iran’s aviation sector has been used to transport weapons, personnel and other cargo connected with state activities.

Iran rejects the broader U.S. sanctions campaign and has faced aviation restrictions for many years.

The latest measures are significant because they extend beyond airlines themselves. Companies outside Iran can face sanctions exposure when dealing with designated businesses, creating practical problems for international airline operations.

Why Ground Handling and Fuel Matter So Much

An international airline cannot operate simply because its aircraft can physically reach another country.

Every overseas flight depends on a large network of companies. Airports, fuel suppliers, ground handlers, payment companies, ticketing platforms and other businesses may all be involved.

Secondary-sanctions exposure can therefore create a powerful deterrent for companies outside the United States.

Even when a particular flight has not formally been prohibited by a local aviation authority, a service can become difficult to operate if essential commercial partners are unwilling to handle the aircraft.

Important services can include:

• Aircraft refuelling
• Airport and ramp handling
• Passenger and baggage processing
• Aircraft maintenance support
• Ticket distribution and sales
• Cargo handling
• Financial and payment services

This explains why the consequences for passengers can extend beyond the airlines specifically named by the United States.

Which Iranian Airlines Were Targeted?

The 27 airlines designated by OFAC include established operators and newer carriers.

Among them are Iran Air Tour, Iran Aseman Airlines, Kish Airlines, Qeshm Air, Sepehran Airlines, Taban Airlines, Zagros Airlines, Chabahar Airlines, Fly Persia Airlines, Karun Airlines and Varesh Airlines.

The list also covers Air Shiraz, Asa Jet Airline, Ata Airlines, Atlas Aviation Group, Ava Airlines, Erwan Airline Company, Fly Kish Airlines, Jsky Airlines, Lad Airways, Mehr Airways, Nasim Air, Pars Oghyanous Kish Company, Raimon Airways, Saha Airlines, Soroush Air and Toos Airlines.

Mahan Air was already subject to U.S. sanctions before the September action.

Treasury also targeted companies and intermediaries outside Iran that Washington said supported aviation activities linked to Iranian carriers. Those entities were located in markets including Türkiye, the United Arab Emirates, Malaysia and Kazakhstan.

Turkey Becomes Critical for Travellers Seeking Alternative Connections

Turkey has long been one of the most important gateways for Iranians travelling internationally.

Istanbul’s extensive aviation network allows passengers to connect with destinations across Europe, Asia, Africa and the Americas. That makes reaching Turkey especially important when direct international flight choices from Iran become limited.

With uncertainty surrounding Iranian-operated international services, travellers can instead cross Iran’s north-western frontier and continue towards Turkish airports.

The disadvantage is the journey itself.

Travelling by road adds border procedures, road transfers and significantly more travel time. Demand can also place pressure on buses, taxis and other cross-border transport.

Passengers who previously completed a journey by air may therefore need to combine several transport modes before reaching an international airport.

Armenia Provides Another Overland Exit

Armenia has also become important because of its land border with Iran.

Travellers can move north through the border and continue towards Yerevan. From the Armenian capital, passengers can search for international air connections without relying on an Iranian-operated flight for the first part of their journey.

This option is particularly relevant when services through other regional aviation gateways are unavailable or uncertain.

However, shifting thousands of passengers from aircraft to roads creates its own problems. Border congestion, limited transport capacity, accommodation demand and last-minute ticket purchases can all raise the overall cost and complexity of travelling.

Not Every Iranian International Flight Has Stopped

It is important to distinguish between severe disruption and a complete closure of Iran’s international aviation system.

The sanctions do not automatically mean that every Iranian international passenger flight disappeared on 23 September.

Some services continued around the time the latest restrictions took effect, and the ability of individual Iranian airlines to operate depends partly on destinations, local authorities and whether foreign service providers continue dealing with them.

China and Russia have opposed unilateral U.S. sanctions against Iran. This means the effect of the American measures may differ considerably from one market to another.

Passengers should therefore avoid assuming that either all flights are operating normally or that all international Iranian services have stopped.

The situation is route-specific and can change rapidly.

International Airlines Add Another Layer of Pressure

Iranian travellers also depend heavily on foreign airlines.

When international carriers reduce or suspend services to Iran because of security, operational or commercial concerns, the effect combines with restrictions facing Iranian airlines.

This can remove capacity from both sides of the market.

A traveller who loses an Iranian-operated flight cannot necessarily switch to a foreign carrier if that airline has also suspended services.

That helps explain why Turkey and Armenia are becoming increasingly important as surface gateways. Travellers can leave Iran by road before connecting to flights from airports outside the country.

Higher Costs Could Reshape Regional Travel

The biggest immediate impact for ordinary passengers is the loss of simple travel choices.

A direct or one-stop air journey can turn into a complicated itinerary involving taxis, coaches, border crossings, overnight accommodation and another flight.

Last-minute bookings can further increase costs.

For tourism, this creates several potential consequences. Outbound Iranian leisure travel could weaken if journeys become too expensive or difficult. Business travel could face similar challenges, while travellers visiting friends and relatives may have to spend more time reaching their destinations.

Turkey and Armenia, meanwhile, could see additional demand for border transport and onward aviation connections.

Wider Consequences for Iran’s Aviation Industry

Iran’s aviation industry has operated under international restrictions for decades. Access to aircraft, spare parts, maintenance services and international financial systems has repeatedly presented challenges.

The September 2026 measures deepen that pressure by extending U.S. sanctions across another 27 airlines and targeting companies that Washington says facilitate Iranian aviation activities.

The international reach of U.S. financial sanctions is particularly important. Many global businesses rely on access to U.S. dollars, banks or American markets.

That can lead companies to avoid sanctioned counterparties even when they are located far outside the United States.

For airlines, losing commercial support abroad can be almost as disruptive as losing permission to fly into a particular airport.

Travellers Face a Fast-Changing Situation

Anyone planning travel involving Iran now faces unusually high uncertainty.

Passengers should check their flight status directly with the operating carrier before starting their journey. Travellers using overland alternatives should also confirm border-entry requirements, onward transport availability and immigration rules for every country involved.

Flight schedules can change quickly when airlines lose airport services or when aviation authorities introduce new restrictions.

Tickets involving separate road and air journeys also carry additional risks. If a delayed border crossing causes a passenger to miss an independently booked flight, normal airline connection protection may not apply.

Conclusion: Iran and Turkey Travel Faces New Pressure as US Aviation Sanctions Push Passengers Overland

Iran and Turkey travel is entering a more difficult period as U.S. aviation sanctions squeeze Iranian airlines and increase pressure on the foreign businesses needed to keep international flights operating. The designation of 27 Iranian carriers, combined with the expiry of a temporary civil-aviation wind-down authorisation on 23 September, has increased uncertainty surrounding international operations.

The result is not a verified total shutdown of Iranian aviation. Some routes may continue depending on the destination and available services. However, fewer dependable air options are pushing more passengers towards alternative journeys through Turkey and Armenia.

For travellers, that can mean longer journeys, border congestion, additional transport costs and expensive last-minute onward flights. Until international aviation links stabilise, the expanding use of overland corridors shows how sanctions aimed at Iran’s aviation sector are also changing the practical way ordinary passengers move across the region.
