The Fort Worth air traffic control center suspended operations from 3:00 p.m. to 5:30 p.m. so that the facility could be disinfected, according to the Federal Aviation Administration, which said Wednesday evening that a single confluence of events and bad weather had led to the disruption.

“The FAA closed the airspace inside and outside of DFW Airport until 5:00 p.m. Central time,” Dallas-Fort Worth International Airport said in a statement. “This is due to a mandatory sanitation cleanup of the FAA offsite facilities that control the airspace in DFW.

The airport, which served around 75 million passengers last year before the pandemic, has urged travelers to check with airlines for changes to their flights.
A spokesperson for Love Field, which is operated by the city of Dallas, said departures and arrivals were temporarily suspended at the airport.

About an hour later, an FAA spokeswoman said a ground stop was lifted. It also noted that the flights crossing the airspace served by the control center had continued to operate and had been able to communicate with other control centers. The spokeswoman said air traffic could still be affected by the weather in the area, where there were thunderstorms Wednesday evening.
