The U.S. has announced a significant escalation in sanctions against Iranian airlines, declaring that all such operations worldwide will cease by September 23. Treasury Secretary Bessent stated that Iranian airlines face an imminent shutdown, threatening those who provide support to these airlines with secondary sanctions. Following this announcement, major carriers including Turkish Airlines and Pegasus have suspended their flights to Iran. The pressure on the Iranian aviation industry mounts as compliance with U.S. demands spreads across neighboring countries like Turkey and Iraq. With this move, the U.S. aims to isolate Iran further amid ongoing tensions, prompting fears of a total operational blackout for Iranian air travel.
