Dallas Outage Disrupts 1,800+ Flights, FAA Pushes Reforms

Dallas Fort Worth International Airport (DFW) and Dallas Love Field Airport resumed operations the next day after a major telecommunications outage on September 19, 2025, that caused the Federal Aviation Administration (FAA) to impose ground stops and restrictions.

The outage was caused by a failure in telecommunication equipment provided by Frontier Communications, affecting the FAA’s Dallas Terminal Radar Approach Control (TRACON) facility.

The failure damaged primary and secondary fiber optic lines, which are essential for radar data, radio communications, and air traffic control computer systems.

Due to the communication disruption, FAA controllers grounded all departing flights and reduced inbound traffic until emergency procedures and backup systems were activated.

American Airlines, the largest carrier at DFW, canceled more than 200 flights and faced delays on over 500, while Southwest Airlines reported more than 1,100 delays.

Once again, the incident highlighted weaknesses in the aging US air traffic control infrastructure, with the FAA calling for tech modernization.

Recognizing the vulnerability in US aviation safety, the Big Beautiful Bill is allocating $12.5 billion to upgrade the FAA’s National Airspace System. This includes modernizing radars, telecommunications, TRACONs (Terminal Radar Approach Control), and runway safety tech.
