FAA Warns U.S. Airlines Over Saudi Arabia Flight Safety After Deadly Houthi Strikes

Federal Alert Follows Weekend Attacks on Riyadh Airport

The Federal Aviation Administration ordered U.S. airlines to exercise caution when flying in or around Saudi Arabia after deadly strikes claimed by Yemen’s Iran-backed Houthis forced the closure of King Khalid International Airport in Riyadh. The FAA issued its Notice to Airmen late Sunday, citing safety-of-flight risks associated with ongoing military activities and interference with navigation systems across the kingdom. The warning, which remains in effect until December 10, marks a significant escalation in regional tensions that now directly threaten commercial aviation.

The attacks escalated sharply on Saturday when a projectile struck a passenger terminal at the Riyadh airport, killing at least 13 people and wounding more than 300. A follow-up strike on Sunday killed one additional person and injured 11 more. King Khalid International Airport remained closed through at least 5 p.m. EDT Monday as Saudi authorities assessed damage and security threats.

“Threats could pose a potential risk to aircraft at all altitudes, including overflight, the arrival, and departure phases of flight,” the FAA stated, describing the situation as “potentially hazardous.”

Airlines suspended flights to the airport in response to the violence, with some carriers canceling service for the remainder of the week. The U.S., Australia, and other countries issued travel advisories warning citizens against travel to the region. The United Kingdom Embassy in Saudi Arabia advised on Monday “against all but essential travel to the cities of Jeddah and Dammam and to all Saudi airports.”

Delta’s Riyadh Launch Faces Uncertain Future

The FAA warning creates immediate uncertainty for Delta Air Lines, which plans to launch its first nonstop flight from Atlanta to Riyadh on October 23. The route would become Delta’s first direct service to Saudi Arabia and the first nonstop U.S.-Riyadh service operated by an American airline. The carrier initially planned daily flights through October 30 before moving to three weekly Airbus A350-900 flights.

CEO Ed Bastian addressed the security situation in an interview last week, before Saturday’s deadly terminal strike.

“Safety is going to make the call,” Bastian said when asked whether Delta would operate the flight as planned.

As of Sunday night, Delta had not changed its launch plans publicly, according to a company spokeswoman. The airline now faces a critical decision with less than two weeks remaining before the inaugural service. Most U.S. airlines do not maintain direct flights to Saudi Arabia, though some major carriers serve Riyadh through codeshare partnerships with international airlines.

Cargo Operations Already Underway Despite Escalation

FedEx launched its first dedicated flight into Saudi Arabia in September 2025, operating a Boeing 777 freighter six times per week. The cargo service connects the Americas and Europe to Riyadh, with onward connections to Guangzhou and Shanghai. The company did not immediately comment on whether the FAA warning would affect its freight operations, which typically face different risk calculations than passenger services.

The FAA notice applies to all operators of U.S.-registered aircraft, encompassing both passenger airlines and cargo carriers. The warning specifically flags threats at all altitudes, meaning even aircraft transiting Saudi airspace at cruise level could face danger from missile systems or navigation interference. The guidance covers overflight operations as well as arrival and departure phases, effectively blanketing the entire Saudi airspace with heightened caution requirements.

Regional Conflict Disrupts Commercial Aviation

The Houthi attacks represent the latest spillover of regional military conflict into commercial aviation corridors. Yemen’s Iran-aligned Houthis warned airlines and travelers to avoid Saudi airports following the Riyadh strikes, effectively issuing their own counter-advisory to the aviation industry. The group has previously targeted Saudi civilian infrastructure during the ongoing conflict.

The U.S. Embassy in Jordan issued a travel advisory on Friday specifically pointing to the Riyadh airport attacks. Embassy officials wrote that Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure resulting in civilian casualties. The advisory warned that hostilities have the potential to escalate rapidly and urged Americans to monitor the situation closely if planning travel to or from the region.

The European Union Aviation Safety Agency (EASA) also recommended on Friday that airlines avoid additional portions of Saudi airspace after the Houthis struck Riyadh’s airport. The European regulator’s guidance preceded the Saturday terminal attack, suggesting aviation authorities across multiple continents had already identified growing risks before the deadliest incident occurred.

Trump Administration Faces Aviation Security Challenge

The FAA operates under Transportation Secretary Sean Duffy’s department and is led by Administrator Bryan Bedford. The Sunday notice represents the Trump administration’s response to a direct threat to U.S. commercial aviation interests in a strategically vital region. The administration must now balance maintaining air service links with a key Middle Eastern ally against passenger safety concerns.

The escalation has already forced carriers to reassess operations across the region. Riyadh’s airport closure and repeated attacks complicate schedules for multiple airlines, creating uncertainty for both passenger and cargo operations. Delta’s planned launch now carries additional scrutiny as the first major test of U.S. airline commitment to Saudi routes amid active military conflict.

The December 10 expiration date for the FAA warning suggests aviation authorities expect either a resolution or clearer picture of the security environment within roughly two months. However, the notice can be extended or modified based on evolving conditions on the ground. Airlines maintaining or planning Saudi operations face difficult decisions about risk tolerance, customer safety, and strategic commitments in an increasingly volatile regional landscape.
