**Saudi airspace remains open despite escalated Houthi missile and drone strikes in September 2026 targeting energy, military, and aviation infrastructure deeper inside the kingdom, including areas near Riyadh, Tabuk, and Yanbu.** The European Union Aviation Safety Agency issued a Conflict Zone Information Bulletin on September 30 advising operators to avoid a designated zone in the Jeddah Flight Information Region (FIR OEJD) at all altitudes while exercising caution elsewhere, citing risks from kinetic activity tied to the US-Iran conflict and Houthi operations. Saudi authorities have maintained commercial operations across main hubs and overflight corridors, consistent with prior patterns of absorbing localized threats through intercepts and temporary alerts rather than broad NOTAM closures. A recent Flydubai emergency diversion and isolated airport disruptions have not triggered general suspension. Traders price low odds of full closure by year-end because Saudi policy prioritizes connectivity and revenue, though further escalation in Red Sea or Yemen-related attacks or shifts in regional diplomacy could alter that assessment before key resolution windows.
