Recent Houthi missile and drone strikes on Saudi airports, including multiple attacks on Riyadh’s King Khalid International Airport in early October 2026, have triggered temporary suspensions of operations, hundreds of flight cancellations, and expanded aviation safety advisories from EASA covering additional airspace sectors. These developments, coupled with Houthi statements designating Saudi skies as a military operations zone, have heightened risks of misidentification, debris, and further strikes, prompting carriers to suspend routes while Saudi authorities have not issued a nationwide NOTAM closing the Jeddah FIR to commercial traffic. Traders monitor escalation signals from Yemen, Saudi defensive responses, and any diplomatic or military shifts that could prompt an official full closure or rapid de-escalation before year-end deadlines.
