More than 1,800 flights were delayed and hundreds canceled at Dallas-area airports Friday, September 19, following a telecommunications outage that prompted Federal Aviation Administration ground stops. The Dallas airport disruptions affected both Dallas Fort Worth International Airport and Dallas Love Field operations.
The FAA attributed the Dallas airport problems to local telephone company equipment issues unrelated to FAA systems. The telecommunications failure created widespread flight schedule disruptions across both major Dallas airport facilities.
“The FAA is working with the telephone company to determine the cause,” the agency said regarding the Dallas airport telecommunications problems. The FAA implemented traffic slowdowns due to the reported local telephone company equipment failure.

The FAA halted departures to Dallas Fort Worth until 11 p.m. ET and to Dallas Love Field until at least 8:45 p.m. FlightAware reported airlines canceled 20 per cent of flights at Dallas airports during the telecommunications disruption.

The ground stops prevented normal Dallas airport departure operations while telecommunications systems remained compromised.
American Airlines and Southwest face major schedule impactsAmerican Airlines canceled more than 200 flights and delayed over 500, nearly all connected to the Dallas airport telecom outage, affecting a quarter of its schedule. The Dallas airport disruption significantly impacted American’s hub operations at Dallas Fort Worth.
Southwest Airlines delayed more than 1,100 flights, representing 27 per cent of its schedule, according to FlightAware flight tracking data. Southwest’s Dallas Love Field hub experienced extensive operational challenges during the telecommunications failure.
The Dallas airport telecommunications problems created cascading effects throughout both airlines’ national networks.
FAA communications issues continue throughout 2025The FAA has encountered numerous communications problems this year beyond the Dallas airport incident. Thursday saw the FAA slow flights into Denver International Airport due to automation issues between approach control towers and air traffic control systems.
Manual handoff procedures replaced automated systems at Denver, causing delays averaging 30 to 45 minutes. The Denver incident preceded the more severe Dallas airport telecommunications failure by one day.
The pattern of FAA communication problems demonstrates ongoing system vulnerabilities affecting multiple airports.
Congress funds air traffic control system overhaulA series of issues involving aging US air traffic control systems prompted Congress to award initial $12.5 billion funding in July for system overhauls. FAA leaders report technology issues occur almost daily within current infrastructure.

The FAA air traffic control network problems developed over years but gained public attention following high-profile incidents. Recent mishaps include near-misses, staffing shortages, and a catastrophic January crash between a US Army helicopter and regional American Airlines jet killing 67 people.
The Dallas airport telecommunications failure adds to mounting evidence supporting comprehensive air traffic control modernization efforts.
Infrastructure vulnerabilities highlight system modernization needsThe Dallas airport telecommunications outage demonstrates critical infrastructure dependencies affecting aviation safety and efficiency. Local telephone company equipment failures can disable entire airport operations despite backup systems.
The Dallas airport disruption illustrates broader challenges facing aging air traffic control infrastructure. The telecommunications failure affected thousands of passengers and highlighted system vulnerabilities requiring immediate attention.
Modern aviation systems require robust telecommunications infrastructure to maintain safe and efficient operations across the national airspace system.
