Saudi authorities extended the closure of King Khalid International Airport in Riyadh through at least October 17 following Houthi missile and drone strikes on October 10 and 11 that killed at least 14 people and injured hundreds. A NOTAM and statements from the General Authority of Civil Aviation cite the need for safety inspections and operational readiness assessments amid ongoing regional threats. International carriers including Etihad, Lufthansa Group, and Air France-KLM have suspended or extended cancellations on Riyadh routes, while regulators such as the FAA and EASA issued caution advisories for Saudi airspace. Saudi coalition forces reported intercepting additional Houthi projectiles, but further strikes remain possible. Reopening timelines hinge on completed security procedures, reduced attack frequency, and airline decisions to resume schedules, directly shaping probabilities for achieving 50+ daily departures within specific windows.
