Dallas lies about 31 miles south of McKinney. Flight disruptions at Dallas-Fort Worth International Airport and Dallas Love Field expanded Monday after a failure at a Federal Aviation Administration air traffic control facility in Philadelphia. FlightAware recorded hundreds of cancellations at DFW, where departing flights were running about 49 minutes late and delays were increasing.
The facility also directs traffic involving Kennedy, LaGuardia and Newark, sending effects to airports nationwide. Newark Liberty International Airport experienced major disruptions linked to the same center in spring 2025. The FAA said its main data connection failed Monday morning, and a fiber-optic line was found cut when staff tried to use the backup.
Transportation Secretary Sean Duffy said an Amtrak construction crew caused the damage.
FAA Administrator Bryan Bedford said the agency was installing another circuit while repairs proceeded, and Verizon technicians were working on service restoration. The fiber repair could require about 13 hours, while the replacement connection could restore the main line sooner. By early afternoon, some operations had resumed at LaGuardia, Kennedy and Philadelphia, although significant delays were expected through the day.
Airlines were allowing some fee-free flight changes, and the FAA told travelers to verify flight status with their airline before heading to an airport. The FAA also started testing an artificial-intelligence system for controller scheduling and weather conflicts in the Washington, D.C., area. The system was not connected to Monday's outage.
