US Treasury Secretary Bessent: About 80%-90% of Iran’s international flights have been suspended

The striking element is the source: a US Treasury Secretary quantifying Iran's aviation isolation, which frames the disruption as an economic-pressure outcome rather than a purely operational one. If the figure holds, it hits the narrow slice of Iranian commerce that still moves by air — business travel, high-value cargo, and the diaspora links that sanctions have not fully severed. The absence of stated cause leaves the key question open: whether this reflects enforcement action, airline risk assessments, or something else entirely.
