EASA Extends Iran Airspace Avoidance Bulletin to 16 November 2026, Issues New Saudi Arabia Warning

On 30 September 2026, the European Union Aviation Safety Agency revised its conflict-zone information bulletin for Iran, CZIB-2026-04-R2, extending its validity to 16 November 2026 without changing the core recommendation. The bulletin, first issued 8 July 2026, advises operators not to fly within the Tehran Flight Information Region, designated OIIX, at any altitude or flight level. EASA cites strikes on 28 February 2026, Iran's subsequent retaliation, a ceasefire it describes as fragile, recurrent Iranian action against commercial shipping near the Strait of Hormuz, and an Iranian air force and air-defence posture kept at high alert.

The same 30 September review extended bulletins for Iraq (CZIB-2026-05-R2), Lebanon (CZIB-2026-06-R2) and the Persian Gulf and Gulf of Oman (CZIB-2026-07-R3) to 16 November, and extended the Jordan bulletin (CZIB-2026-08-R2) to 16 October. On 1 October, EASA revised its Syria bulletin to run until 30 November 2026. EASA also issued a new bulletin, CZIB-2026-09, on 30 September, covering the Jeddah Flight Information Region (OEJD) over Saudi Arabia, valid until 16 November. EASA states that in September the Houthis significantly increased the frequency and geographic scope of attacks on Saudi maritime, energy and infrastructure targets, including aviation-related sites, with strikes reaching the Riyadh, Tabuk and Yanbu areas; its recommendation covers a defined portion of the Jeddah FIR bounded by named navigation points.

The FAA's standing prohibition on US operators in the Tehran FIR runs through 31 October 2027. France, Germany, Italy, the United Kingdom and Canada have also issued avoidance notices or recommendations against entering the Tehran FIR. Iran's airspace remains formally open but is avoided in practice by almost all international carriers as of October 2026. The next scheduled regulatory review dates are 16 October 2026 for Jordan and 16 November 2026 for Iran, Iraq, Lebanon, the Persian Gulf and Saudi Arabia.

In October 2026, Europe-to-Asia flights are routing via two principal corridors: a southern path over Egypt, the Red Sea and Saudi Arabia into the Arabian Sea, and a northern path through the Caucasus and Central Asia. A small number of regional operators overfly the eastern Tehran FIR where their home regulators have not issued an avoidance notice.

This is a case of regulatory avoidance guidance running well ahead of any formal airspace closure: Iran's FIR is still legally open, yet the combination of EASA, FAA and multiple national bulletins has made it commercially unusable for almost all international carriers. Conflict-zone bulletins function this way across the segment — they are advisory, nation-by-nation, and routinely diverge in scope and duration, so a carrier's actual routing depends on which regulator it answers to, not on a single shared standard.

The new Jeddah FIR bulletin, CZIB-2026-09, shows the risk perimeter widening rather than shrinking, with Houthi strikes reaching Riyadh, Tabuk and Yanbu pulling part of the southern Europe-to-Asia corridor itself into the avoidance zone. That corridor, alongside the northern path through the Caucasus and Central Asia, is now the main alternative to Iranian airspace, so any further narrowing of the Jeddah routing options would concentrate traffic onto fewer corridors and add distance and fuel burn across the network.

The next concrete checkpoints are 16 October for Jordan and 16 November for Iran, Iraq, Lebanon, the Persian Gulf and Saudi Arabia, when each bulletin is either extended again or allowed to lapse. Whether the Jeddah FIR restriction is widened, held steady, or narrowed at that November review will signal whether the southern corridor keeps its current capacity or operators are pushed further toward the northern route.
