Riyadh's King Khalid International Airport remains closed following multiple Houthi missile strikes in early October 2026 that killed at least 18 people and injured hundreds, prompting Saudi authorities to extend operational suspension through a Notice to Airmen until 21:00 UTC on October 17 for safety inspections and facility assessments. Nearly all scheduled departures were canceled in the initial days, with international carriers including Lufthansa Group, Air France-KLM, Etihad, and several Indian airlines extending suspensions well beyond that date amid regional security advisories from the FAA and EASA. Trader focus centers on whether GACA clears the airport for meaningful commercial activity shortly after the NOTAM expires, airline willingness to resume schedules, and any further attacks or diplomatic developments in the Yemen conflict that could alter risk assessments or delay recovery of 50+ daily departures.
