Iran’s aviation network is facing fresh disruption as new US aviation sanctions restrict Iranian airlines’ access to international airports, airspace and essential aviation services. The measures are making international travel increasingly difficult for Iranian passengers, with thousands now turning to land routes through neighbouring countries as commercial flights are cancelled or suspended.
The latest restrictions took effect on September 23, following a September 8 decision by the US Treasury Department to sanction the remaining Iranian airlines. The move has further isolated Iran flights from key regional aviation networks, with several neighbouring countries also ending airport and airspace services for Iranian carriers.
For travellers, the impact is already being felt beyond cancelled flight schedules. Routes through Turkiye and Armenia have become increasingly important alternatives, but growing demand has created congestion at several land crossings. Reports cited by Al Jazeera indicate that some bus fares to Turkiye have risen to around four times their usual levels.
Regional Flight Disruptions Deepen
The latest measures follow a series of restrictions affecting Iranian airlines operating internationally. Oman, Azerbaijan and Georgia have stopped providing airspace or airport services to Iranian carriers, while Baghdad Airport has also become unavailable to Iranian airlines. Flights to Najaf in Iraq, however, were continuing as of September 23.
Iran had already announced the cancellation of flights to Baghdad and Muscat ahead of the new sanctions taking effect. Iranian aviation authorities said they were working to redirect Baghdad-bound services to Najaf, while negotiations with Oman were also under way. At the time, Iranian officials said other international services, including flights to Istanbul, were expected to continue.
The US Treasury’s September 8 action targeted 36 individuals and entities connected with Iran’s aviation sector, including 27 airlines, according to the department. Washington said the measures were intended to target aviation networks it alleges are involved in transporting weapons, personnel and illicit cargo. The Treasury also warned that foreign companies providing support to sanctioned Iranian airlines could face consequences under US secondary sanctions.
Although the United States cannot directly close foreign airspace, aviation analysts told Al Jazeera that targeting services such as refuelling, landing support and other ground operations can significantly restrict an airline’s ability to operate internationally.
Travellers Shift Towards Land Routes
With fewer international flight options available, overland travel has become an increasingly important alternative for Iranian passengers seeking to leave the country. Land crossings towards Turkiye and Armenia are experiencing heightened demand, while congestion is adding further pressure to an already disrupted travel network.
The consequences extend beyond individual travellers. Restrictions on international aviation can affect tourism, business travel, cargo movements and the wider network of services supporting airlines. Previous restrictions had already reduced Iran’s access to international aviation infrastructure, while the latest measures are creating additional operational and commercial challenges for its carriers.
Iran’s aviation sector has faced extensive sanctions for years, with major carriers including Iran Air and Mahan Air already subject to US restrictions. The latest action broadens those measures to the remaining Iranian airlines and places greater pressure on companies outside Iran that continue providing aviation-related services.
The changing flight landscape is also affecting regional connectivity. While some services remain available, the loss of airport access and support in several neighbouring countries is reducing the number of practical international travel options available to Iranian passengers.
For travellers planning journeys from Iran, the situation remains fluid, with flight schedules and border conditions subject to further changes. The shift towards overland routes highlights how quickly aviation restrictions can reshape travel patterns, particularly when neighbouring countries also alter access to airports and airspace.
As the latest US measures take effect, Iran’s international aviation network is entering another period of uncertainty. For passengers, the immediate reality is a more complicated journey, fewer flight choices and greater reliance on alternative routes. Whether these disruptions become temporary travel complications or lead to longer-term changes in regional connectivity will depend on how airlines, neighbouring countries and governments respond in the weeks ahead.
