US Treasury Secretary Scott Bessent said Iranian airlines would be effectively 'shut down' worldwide starting September 23, warning that airports and companies servicing Iranian carriers risk losing access to the US dollar financial system. In response, Turkish Airlines, AJet, and Pegasus have already cancelled Iran flights, with Turkish Airlines and AJet showing no scheduled Iran routes until March 2027 and Pegasus pulling flights from its booking system. The move marks a significant escalation of US economic pressure on Tehran as the war approaches its seven-month mark, aiming to further isolate Iran's aviation sector and cut off a key transportation and economic lifeline. It follows broader sanctions pressure that has already strained Iran's economy.
