The U.S. Federal Aviation Administration (FAA) has urged American airlines to exercise caution when flying to or over Saudi Arabia, citing security threats linked to ongoing military activity and interference with aircraft navigation systems.
The advisory, issued Sunday, warns that potentially hazardous conditions could affect aircraft at all altitudes, including during overflights, arrivals and departures.
The notice remains in effect until December 10 and also applies to operators of U.S.-registered aircraft.
The warning follows reported strikes on Riyadh’s international airport on Saturday and Sunday. According to the report, the Saturday attack killed 13 people and wounded more than 300.
Riyadh airport remains closed to flights through at least 5 p.m. Eastern Daylight Time on Monday, as authorities respond to the security situation.
Airlines assess flight operations
The FAA advisory raises questions about planned commercial services to the Saudi capital, including Delta Air Lines’ scheduled launch of direct flights from Atlanta to Riyadh on October 23.
Delta did not immediately respond to a request for comment. However, Chief Executive Officer Ed Bastian said last week that safety would determine whether the airline proceeds with the planned service.
Other major U.S. airlines serve Riyadh through codeshare arrangements with partner carriers.
Cargo operations are also part of the aviation network connecting Saudi Arabia with international markets. FedEx launched its first dedicated flight to Saudi Arabia in September 2025, operating a Boeing 777 freighter six times a week. The service connects the Americas and Europe to Riyadh, with onward links to Guangzhou and Shanghai.
The FAA’s warning underscores the aviation risks posed by the region’s ongoing security situation, particularly for aircraft operating near areas affected by military activity or disruptions to navigation systems.
