## Prediction

Over the next 24 hours, several key international airports and civil aviation authorities will issue clarifying statements or quiet operational notices cutting scheduled services by Iranian carriers to preserve dollar access ahead of the 23 September deadline. Governments in Europe, the Gulf, and South Asia will avoid high-profile defiance, signaling de facto alignment with US secondary sanctions. This will further isolate Iran’s civil aviation and reinforce Washington’s leverage going into any renewed Iran–US talks. Confirmation would be cancellations or timetable changes for Mahan Air, Iran Air, and others; denial would be explicit declarations by major hubs (e.g., Istanbul, Doha) that they will continue unrestricted service despite US threats.

## Drivers

- US announcement that any airport serving Iranian airlines will be cut off from USD clearing from 23 September
- Broader escalation of US–Iran confrontation across airspace and sanctions
- Historic airport compliance behavior with US dollar-based sanctions
