By 00:01 UTC on September 29, the United Arab Emirates indefinitely suspended all flights by Iranian airlines to comply with secondary United States sanctions. The UAE cited the need to protect its aviation industry from being excluded from the US dollar system. In immediate retaliation, Iran closed its airspace to all UAE-registered aircraft, including Emirates and Etihad.

The airspace closure forced immediate flight diversions for UAE carriers. Flydubai flights traveling to Russia and the Caucasus were forced to detour over Iraq and Turkey.

By 08:30 UTC on September 27, Turkey had also severed major Iranian financial and air links, forcing Iranians in Turkey to make a 2,400-kilometer overland journey to return home. The UAE had formally suspended all flights by Iranian airlines earlier on September 24.

How the story developed

By 11:10 UTC on September 10, the United States Treasury Department designated 36 entities, including 27 Iranian airlines, effectively targeting the country's entire remaining aviation sector. The sweeping crackdown aimed to completely sever Iran's commercial aviation sector from the global financial system.

The US Treasury suspended general licenses that previously allowed overflights and the operation of US-origin aircraft in Iran. Additionally, nine third-country intermediaries in Turkey, Malaysia, Kazakhstan, and the UAE were designated for facilitating aircraft and parts smuggling.

The September 10 sanctions coincided with a record low for the Iranian rial and escalating military tensions in the Strait of Hormuz. The US Treasury set a September 23 deadline for compliance with the secondary sanctions.

Following the September 23 deadline, US secondary sanctions forced international airports in Iraq and Azerbaijan to suspend operations by the 27 sanctioned Iranian airlines. The US Treasury claimed the campaign was successfully isolating Iran's economy amid regional conflict.
