U.S. Mission in Saudi Arabia Warns of Flight Disruptions and Airspace Closures

The U.S. Mission in Saudi Arabia issued a security alert on 18 October 2026 telling Americans currently in the Middle East to exercise heightened vigilance because of what it called a complex security environment. The alert warns travellers to expect potential flight cancellations, airspace closures and travel disruptions.

Key facts

• Date of alert: 18 October 2026
• Who it concerns: Americans in the Middle East, and those travelling to or from the region
• Main risks cited: flight cancellations, airspace closures, travel disruptions
• Flight status sources named: Riyadh (kkia.sa), Jeddah (kaia.sa), Dhahran (kfia.sa) airports and Flightradar24
• U.S. government employee restrictions: special authorisation needed for Riyadh's King Khalid International Airport and for travel to several provinces and cities

Why is this happening?

The alert states that Iranian-supported Houthis have carried out hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure that caused civilian casualties and severe travel disruptions. It warns that the hostilities could escalate rapidly beyond the immediate area.

The U.S. Mission also says Iran and groups supportive of Iran may target other U.S. interests overseas, including locations associated with the United States and Americans around the world, such as U.S. businesses and other institutions.

How do I check my flight?

Travellers are told to check their flight's departure status with the airline or through the airport websites for Riyadh, Jeddah and Dhahran, or via Flightradar24's Saudi Arabia airport data. The alert advises anyone travelling to or from the Middle East to monitor airport and airline operations and to develop contingency plans in advance. If a flight is affected, travellers should contact their airline directly for change details.

What restrictions apply to U.S. government employees?

U.S. government employees working in Saudi Arabia need special authorisation to use King Khalid International Airport in Riyadh. They are not allowed to travel within 20 miles of the Yemen border because of safety risks, and they require special authorisation to travel to the provinces of Jizan, Asir and Najran and to the cities of Qatif, Yanbu and Taif.

What should travellers do?

The U.S. Mission advises enrolling in the State Department's Smart Traveler Enrollment Program (STEP) for security updates, and reviewing the travel advisories for Saudi Arabia and Yemen. In the event of an aerial attack, it says to stay away from glass doors, windows and fallen debris and to monitor phones and news outlets for official guidance.

Other advice includes keeping a cell phone charged and pre-programmed with emergency numbers, being aware of surroundings, avoiding demonstrations, large gatherings and areas with a heavy police presence, monitoring local media, following local authorities' instructions, staying alert at locations publicly associated with the United States and keeping a low profile.

Is consular help available?

Regular and emergency consular services remain available for U.S. citizens, who should contact their closest embassy or consulate. Local emergency numbers listed are 911 for unified emergency services, 999 for police, and 997 for ambulance and highway security. The State Department consular call center can be reached at +1-202-501-4444 from abroad or 1-888-407-4747 from the U.S. and Canada.

The alert gives no end date for the warnings or the employee travel restrictions. Travellers in the region should keep monitoring airport and airline updates.
