**Deck**: New U.S. sanctions have halted an estimated 80–90% of Iran’s international flights, with Washington touting the ‘paralysis’ of Tehran’s aviation sector as a pressure tool. Iran has responded with threats against neighboring Gulf countries that enforce the bans, putting regional airlines, migrant workers, and energy markets in a more precarious position.

Iran’s air gateways to the world have narrowed sharply under new U.S. sanctions, with Washington boasting that a vast majority of international flights are grounded and Tehran lashing out at Gulf neighbors that enforce the restrictions.

U.S. Treasury Secretary Scott Besant said the measures he announced have effectively frozen Iran’s civil aviation links. “More than 80% or 90% of international flights from Iran have been halted,” he said, describing what he called a “paralysis” of the sector. He even questioned how Iranian representatives attending the UN General Assembly in New York would manage to get home, underscoring how travel itself has become a pressure point.

Iran has reacted angrily. According to regional reporting, Tehran has threatened to attack countries in the Persian Gulf in response to the sanctions on Iranian airlines and the enforcement of new flight bans. Details of those threats—including specific targets or red lines—haven’t been published, but the message is unambiguous: governments that help choke off Iranian aviation could find themselves treated as front-line participants in Washington’s economic war.

For ordinary Iranians, the immediate effects are painfully concrete. Students, medical patients, business travelers, and diaspora families who rely on a patchwork of international flights—from national carriers to foreign airlines that still serve the country—face abrupt cancellations and uncertain alternatives. Tickets jump in price as capacity disappears, and journeys that once involved a single connection via a Gulf hub turn into multi-leg odysseys through less convenient and often less safe corridors.

The shock doesn’t stop at Iran’s borders. Gulf carriers and airports that once handled high volumes of Iranian passengers now sit in a political squeeze between U.S. sanctions enforcement and their own commercial interests. Migrant workers and traders shuttling between Iran and Gulf economies are stranded or forced onto irregular routes. Insurance underwriters and air traffic managers must now price in the risk that threats emanating from Tehran could translate into attempts to intimidate or disrupt regional aviation.

Strategically, Washington is using Iran’s aviation sector as a lever to constrain the country’s economy and foreign reach without directly striking its oil exports. Airlines are not just about tourists: they move cash, specialists, dual-use technology, and occasionally covert operatives. By targeting Iranian carriers, the U.S. hopes to limit Tehran’s ability to sustain its regional network of allies and proxies without triggering the kind of immediate oil shock that a tanker war in the Gulf would produce.

Yet the same sanctions that cripple Iran’s airlines also deepen its incentive to work around Western-controlled systems. Iranian officials have already leaned more heavily on sanctioned carriers such as Mahan Air to sustain trade and logistics after the U.S. blockade of Iranian sea commerce. Customs data cited by The Wall Street Journal show roughly 1,300 shipments of Chinese dual‑use components—electronics, motors, GPS units and aircraft parts that can be used in drones and missiles—flowing to Iran’s Defense Ministry in the first half of this year, with air cargo playing a growing role as sea routes tighten.

That creates a feedback loop: the more the U.S. and its partners try to choke off visible, regulated channels, the more Iran shifts sensitive activity into opaque, sanctions‑busting pipelines that are harder to monitor but potentially just as effective.

One line captures the new reality: for Iran’s leaders and many of its citizens, getting on a plane is no longer just a travel decision but a measure of how much Washington’s economic warfare reaches into their daily lives.

Key markers to watch now include whether major Gulf and Asian airlines further cut or fully suspend Iran routes, whether Tehran moves beyond rhetoric to concrete military steps against regional infrastructure, and whether China and other partners expand air cargo links that could blunt the impact of U.S. measures while deepening their own entanglement in Iran’s confrontation with the West.
