King Khalid International Airport in Riyadh faced a prolonged shutdown after Houthi missile and drone attacks beginning around October 10, 2026, prompting Saudi authorities to suspend operations for safety inspections and issue prior-permission NOTAMs. Partial reopening occurred on October 25 for domestic flights in Terminal 1 and international services by Saudi carriers in Terminal 2, yet flight tracking data showed persistently low traffic amid renewed threats from the group labeling the facility a target. Most foreign airlines extended suspensions into November or later, citing ongoing regional security risks, with carriers such as Lufthansa, KLM, Air France, and several Indian operators setting staggered restart dates or maintaining cancellations through mid-to-late November. Recent developments include additional Houthi-linked incidents in early November and continued airline schedule adjustments, keeping overall departure volumes below normal levels.
