Deneen DeFiore, vice president and chief information security officer at United Airlines, said Monday at the 10th annual CyberSat conference in Reston, Virginia, that the carrier has begun deploying AI from a defensive perspective. As of Nov. 2, 671 aircraft, or half of United's daily flights, were equipped with Starlink.
Why it matters
United is accelerating both its Starlink rollout and cybersecurity readiness because AI-enabled threat actors are discovering and exploiting weaknesses faster than organizations can respond. The carrier's shift reflects growing pressure on airlines to modernize defenses across connectivity and operational systems.
Reported figures are 671 Starlink-equipped aircraft, about half of United's daily flights, with the deployment timeline cut from two to three years to 18 months. IATA reports GPS jamming and spoofing incidents at tens of thousands per month, though the source does not specify how many of those affect United flights.
The players
Deneen DeFiore
DeFiore is vice president and chief information security officer at United Airlines, responsible for the carrier's information security strategy.
United Airlines
United Airlines is a major U.S. commercial airline headquartered in Chicago, operating one of the largest domestic and international networks in the country.
International Air Transport Association (IATA)
IATA is the global trade association for the world's airlines, which tracks aviation industry safety and security trends including GPS interference.
The details
DeFiore said United uses frontier models to scan its code base and is evaluating continuous red-teaming to secure digital properties. The airline is also implementing access privileges, increased monitoring and containment measures, and testing options for restoring continuity of operations based on minimum core capabilities and decision rights.
Timeline
Monday (Nov. 2, 2026): DeFiore speaks at the CyberSat conference in Reston, Virginia.
Nov. 2, 2026: 671 aircraft are equipped with Starlink.
End of 2027: United targets in-flight connectivity across its entire fleet.
The Tech Race
United's acceleration of Starlink deployment, which cut the original two-to-three-year timeline to 18 months, follows SpaceX's push to sell satellite broadband to airlines as a replacement for legacy in-flight Wi-Fi systems. The carrier is now racing to secure that connectivity against GPS spoofing and AI-enabled threats while competing airlines build their own connectivity stacks.
Passengers on the roughly half of United flights with Starlink can expect faster in-flight connectivity as the rollout continues fleet-wide. Because GPS spoofing has risen sharply, the airline's defenses may affect how reliably flight systems operate for travelers.
The takeaway
Airlines are now treating connectivity and cybersecurity as a single modernization effort, since faster satellite links and AI-driven threats both raise the stakes for fleet-wide defenses. Watch for how quickly United enables Starlink on the flight deck, which will be a key test of its security readiness.
What happens next
United expects its entire fleet to have in-flight connectivity by the end of 2027, with Starlink not yet enabled on the flight deck.
