Ongoing Houthi missile and drone attacks targeting Saudi airports, including repeated strikes on Riyadh’s King Khalid International Airport in October and early November 2026, have triggered localized suspensions, permission-only NOTAMs, and widespread airline cancellations through late November. Saudi authorities have maintained operations across the Jeddah Flight Information Region with targeted restrictions rather than a general commercial closure, despite EASA conflict-zone advisories extended to November 16. This pattern of contained disruption amid Yemen-related escalation explains the low implied probabilities for a full airspace shutdown by year-end deadlines. Further confirmed strikes or expanded international warnings could alter trader assessments before December 31.
