EASA's New Saudi Arabia Airspace Bulletin (CZIB-2026-09): What the Jeddah FIR Warning Says, Which Part Is Off-Limits, and What It Means for Your Flight

For most of 2026 the Middle East airspace story has been about Iran: when the Tehran FIR closed, when it partially reopened, and how airlines threaded the gap between it and the war zones to the west. The southern route over Egypt and Saudi Arabia was the quiet alternative. On 30 September 2026 EASA made that route a little less quiet, publishing a new Conflict Zone Information Bulletin, CZIB-2026-09, for the airspace of Saudi Arabia.

This post explains what the bulletin says in plain language, which part of Saudi airspace it tells EU operators to avoid, what it does not say, and what it means for passengers whose flights normally cross the Jeddah FIR. Everything factual here is taken from the bulletin text itself, which is public on EASA's conflict-zone page; where we interpret, we say so.

What CZIB-2026-09 actually says

The bulletin was issued on 30 September 2026 and is valid until 16 November 2026 unless reviewed earlier. It covers the whole of FIR Jeddah (ICAO code OEJD), at all altitudes and flight levels; the Jeddah flight information region is the single FIR that covers Saudi Arabia, so in practice the bulletin is about the entire country. If the four-letter codes are new to you, our explainer on [what a flight information region is](/blog/what-is-a-flight-information-region-fir-explained) covers them.

EASA's description of the situation has two parts. The first is regional: in its words, as a consequence of the military conflict between the United States and Iran, the regional security situation remains highly volatile, with significant kinetic military activity affecting Saudi airspace. The second is specific to Yemen: in September 2026 the Houthis significantly increased the frequency and geographic scope of attacks against Saudi maritime, energy and infrastructure targets, including in the Red Sea and the Gulf of Aden, and military and aviation-related infrastructure across Saudi Arabia has been repeatedly targeted by missiles and drones.

The sentence that matters most for routing is this one: while the southern and south-western parts of Saudi airspace remain particularly exposed because of their proximity to Houthi-controlled areas in Yemen, recent attacks have demonstrated the ability and intent to strike targets deeper inside Saudi territory, including the Riyadh, Tabuk and Yanbu areas. That is EASA saying the risk is no longer confined to the border strip.

The risks EASA lists, in order

Conflict zone bulletins are careful documents, and the risk list in this one is worth reading closely because it tells you what the agency is actually worried about.

• Misidentification of civil aircraft when air-defence systems are activated during missile and drone attacks. This is the risk behind every major civil-aviation tragedy in a conflict zone, and the bulletin names it first.
• Missile and drone overflights, interception activity and falling debris, meaning an airliner being in the wrong piece of sky when an intercept happens above or below it.
• Exposure beyond the areas previously affected, because the expansion of kinetic activity in September 2026 across a wider part of the kingdom increases the potential exposure of civil aviation, which the bulletin says requires operators to conduct close monitoring and contingency planning.
• Rapid deterioration. EASA credits Saudi Arabia with managing its airspace effectively, including tactical deconfliction and Emergency Security Control of Air Traffic (ESCAT) measures, but says the operating environment remains vulnerable to rapid deterioration.

Which part of Saudi airspace is off-limits

The bulletin's first recommendation is a do-not-operate instruction, not merely advice to be careful. EU operators are told not to operate, at any flight level or altitude, within the part of Saudi airspace defined by the line connecting the navigation points RIBOK, BOSUT, ISLAM, DEKLO, OBSAM and SILPA and the boundary of FIR Jeddah. For the rest of the Jeddah FIR the instruction is softer: exercise caution and take potential risks into account.

EASA does not publish a map with the bulletin, and waypoint names mean nothing to most passengers. Reading the bulletin's own description of where the exposure is greatest, the enclosed area is the part of the kingdom nearest Yemen, in the south and south-west. That is our interpretation of the text rather than a statement in it; airlines and dispatchers plot the exact polygon from the published coordinates. What matters for a traveller is the shape of the decision: a hard no for the southern strip, and a documented risk assessment for everything else, including the main east-west corridors further north.

The other three recommendations are the standard ones for a high-risk bulletin: keep an up-to-date risk assessment and a high level of contingency planning for any operation in the FIR, be prepared for short-notice instructions from the Saudi authorities, and monitor aeronautical publications from Saudi Arabia, the neighbouring states and the operator's own state. Our guide to [reading EASA's Middle East bulletins](/blog/easa-conflict-zone-bulletins-middle-east-explained) explains how these recommendations differ from an outright closure.

What the bulletin does not say

It does not say Saudi airspace is closed. A CZIB is an EU advisory about risk; the airspace itself is managed by Saudi Arabia, and the bulletin explicitly notes the kingdom's ability to manage it. Flights to, from and within Saudi Arabia continue, and the bulletin applies to EASA operators and the third-country operators EASA authorises for EU flights, not to every airline in the world.

It does not say the main corridors are unsafe. The do-not-operate area is a defined polygon; the rest of the FIR carries a caution and a planning requirement. Airlines from outside the EU follow their own regulators, which may be stricter, looser or silent.

It does not predict how long the situation will last. The validity date of 16 November 2026 is an administrative review date, not a forecast; bulletins are routinely extended, revised with an R suffix, or withdrawn early. The same page that hosts this bulletin shows Jordan's bulletin on its second revision and the Persian Gulf bulletin on its third, which gives a sense of how often they are reworked.

Why this matters for the southern corridor

Since the Iranian airspace disruptions began, a large share of traffic between Europe and the Gulf, India and South-East Asia has used what we have called the southern corridor: across Egypt, over the Red Sea, across Saudi Arabia and on to the Gulf states. We described that geography in our post on [Egypt and Saudi Arabia flight routes](/blog/southern-corridor-egypt-saudi-arabia-flight-routes). The new bulletin does not close that corridor, but it changes the maths for the airlines using it in two ways.

First, the southern strip of Saudi Arabia is now formally excluded for EU operators, which removes some routing flexibility for flights heading toward the Gulf of Aden, Oman and the Indian Ocean. Second, and more subtly, the bulletin's language about Riyadh, Tabuk and Yanbu means the risk assessments airlines must keep on file now have to consider the central and north-western parts of the country, not just the border. Yanbu and Tabuk sit along the Red Sea side of the kingdom, exactly where the corridor enters Saudi airspace from Egypt. That does not mean flights will stop using it; it means more airlines will be making an active, documented decision to do so, and some of the more cautious ones may route further north or accept a longer detour.

For a traveller the practical effect is the one we keep describing across this region: longer flights, occasional schedule changes, and the possibility that two airlines on the same city pair fly noticeably different tracks. Our post on [how airlines plan routes around conflict zones](/blog/how-airlines-plan-flight-routes-around-conflict-zones) explains why those differences are normal rather than alarming.

Is it safe to fly over Saudi Arabia right now?

The honest answer is the one the bulletin gives: it depends which part, and the operator carries the responsibility. The southern polygon is a no for EU carriers. The rest of the FIR is open and in daily use, with the explicit caveat that the environment can deteriorate quickly. Flights continue to land at Jeddah, Riyadh and Dammam, and the Saudi authorities have, in EASA's own assessment, demonstrated the ability to manage their airspace when attacks occur.

If you want to check your own flight, the method is the same as for any conflict zone, and we laid it out step by step in [how to check if your flight avoids conflict zones](/blog/how-to-check-if-your-flight-avoids-conflict-zones): look at the flight's recent tracks on a flight-tracking site, compare them with the bulletin's area, and remember that the track flown yesterday is the best predictor of the track flown tomorrow. If your route crosses the south-west of Saudi Arabia on a non-EU airline, that is a reasonable question to ask the airline directly.

What to watch next

Three things would change this picture. A revision of CZIB-2026-09 with a larger polygon, or a withdrawal, would be the clearest signal either way; EASA revisions appear on the same bulletin page with an R suffix. A Saudi NOTAM restricting its own airspace, which would bind every operator rather than only EU ones, would be the next; our guide to [reading a NOTAM](/blog/what-is-a-notam-how-to-read-airspace-closure-notices) explains where to find those. And any change in the Iranian picture, which we track in our [October 2026 Iran airspace update](/blog/iran-airspace-open-or-closed-october-2026-update), would shift traffic back onto or further off the southern corridor.

Until then, the bulletin is best read for what it is: a formal statement by the EU's aviation regulator that the quiet route is no longer entirely quiet, with a clearly drawn line around the part that is off-limits and a request that everyone flying the rest of it keeps their eyes open.
