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 operational suspensions, widespread flight cancellations by carriers such as Lufthansa, Etihad, and Indian airlines, and expanded aviation advisories. The EU’s EASA widened its no-fly recommendations for parts of Saudi airspace, citing Houthi reach into central and northwestern areas and a focus on aviation targets, while OPSGROUP issued broader “do not fly” guidance. Yemen’s Iran-aligned Houthis have declared Saudi skies a military operations zone following Saudi-backed Yemeni offensives and warned commercial flights to avoid the area except over holy cities. Saudi civil aviation authorities have managed localized closures at southern airports like Najran and Jazan through mid-October, with Riyadh operations disrupted but not fully halted. These developments, amid ongoing regional escalation and upcoming Riyadh summits, shape trader focus on the duration and extent of any broader airspace restrictions.
