FAA Tells US Airlines to Exercise Caution on Saudi Arabia Flights, Citing Military Activity and Navigation Interference
Why It MattersAdvisories that cover all altitudes and US-registered operators make route exposure a safety-planning variable for carriers with scheduled or cargo service into a conflict-adjacent hub, not only for those flying directly.
What happened
The Federal Aviation Administration told US airlines to exercise caution when flying to or over Saudi Arabia, citing safety threats tied to ongoing military activities and interference with navigation systems. The FAA Notice to Airmen runs until December 10. It follows strikes on October 10 and October 11 on Riyadh's international airport. The attack on Saturday killed 13 people and wounded more than 300.
"Threats could pose a potential risk to aircraft at all altitudes, including overflight, the arrival, and departure phases of flight," the FAA said, warning of a "potentially hazardous situation." The notice also applies to operators of aircraft registered in the US.
Riyadh airport remains closed to flights through at least 5 p.m. Delta Air Lines is set to begin direct flights from Atlanta to Riyadh on October 23. Delta did not immediately respond to a request for comment on Sunday, but CEO Ed Bastian told CNBC last week that "safety is going to make the call" on whether the airline goes ahead. Other major US airlines serve Riyadh through codeshare partners.
In September 2025, FedEx launched its first dedicated flight into Saudi Arabia. The Boeing 777 freighter operates six times a week, linking the Americas and Europe to Riyadh.
Industry impact & what to watch
An FAA notice that covers every phase of flight and every altitude does more than flag an airport. It removes the usual assumption that overflying a risk area is safer than landing in it, and it reaches US-registered aircraft regardless of who operates them. Charter and fractional operators running US-registered jets are therefore inside its scope, not only the scheduled carriers named in the coverage.
The exposure is uneven across business models. A carrier with a direct service not yet launched, like Delta's planned October 23 start, faces a go or no-go decision. Airlines serving Riyadh through codeshare partners hold the commercial link without operating the aircraft. A dedicated freighter such as FedEx's six-weekly 777 sits between the two, with fixed rotations already in the schedule. Navigation-system interference is a separate hazard from physical strikes, and it can affect routing and approach planning even when the airport itself is open.
The next markers are dated. Delta's October 23 start is the first test of how a direct carrier weighs the notice, and Bastian has said safety will decide it. The Notice to Airmen runs until December 10, so any extension or lapse of the advisory would be the next signal on how the FAA reads the risk.
