Iran cancels flights to UAE as US sanctions ground up to 90% of international aviation
New sanctions effective September 23 have crippled up to 90% of Iran's international flight operations, with the UAE routes among the first to go dark.
Iran’s aviation sector effectively collapsed overnight. As of September 24, 2026, Iranian airlines stopped flying to the United Arab Emirates, a direct consequence of newly intensified US sanctions that gave international service providers a hard deadline: cut ties with Iranian carriers or face consequences.
What the sanctions actually did
The US Treasury’s latest round of measures, which took effect September 23, targeted Iran’s aviation sector with unusual precision. Rather than sanctioning airlines directly, the pressure landed on third-party service providers, the ground handlers, fuel suppliers, insurers, and overflight authorities that keep planes in the air.
US Treasury Secretary Scott Bessent noted that by the compliance deadline, somewhere between 80% and 90% of Iranian international flights had ceased operations.
The UAE cancellations illustrate the cascade. Iran Airtour suspended its Tehran-Dubai routes effective midnight on September 24, even for passengers who had already purchased tickets. Iran Air and Mahan Air have managed to preserve some limited service, mostly to China and Armenia, but the broader network has largely gone quiet.
The reach of these sanctions extended beyond bilateral flight bans. Turkmenistan denied overflight access to Iranian aircraft, forcing at least one Tehran-to-Dushanbe flight to turn around mid-route and return to its origin.

Why Dubai mattered so much
The UAE, and Dubai specifically, has historically functioned as Iran’s informal international gateway. Decades of Western sanctions pushed Iranian commerce toward the Gulf, with Dubai emerging as the primary transit point for goods, capital, and people moving in and out of the Iranian economy.
Air freight matters disproportionately here. Iran has historically relied on air imports for time-sensitive goods, medical equipment, and components that can’t travel overland efficiently. With most international routes now suspended, the logistics chain for those goods gets significantly more complicated and expensive.
The sanctions escalation in 2026 fits into a longer arc of US-Israel pressure on Iran that intensified earlier in the year. Aviation has been a recurring target because it sits at the intersection of dual-use technology concerns and Iran’s broader economic connectivity. Aircraft parts, navigation systems, and avionics have long been subject to export controls, and Iranian carriers have spent years flying aging fleets with limited access to maintenance and spare parts.
The stakes for Iran’s economy
Aviation is not just a convenience sector in Iran. It supports tourism, trade logistics, and the movement of skilled workers. Airlines themselves are significant employers. A sustained collapse of international air connectivity compounds the pressure Iran’s economy is already under from existing sanctions on oil, banking, and finance.
The remaining routes to China and Armenia are a thin thread. China has maintained commercial relationships with Iran despite US pressure, and that corridor may become even more strategically significant as other options disappear. Armenia provides an alternative routing into Europe and Russia for Iranian travelers willing to connect.
