US Air Travel Begins to Recover After Nationwide FAA Ground Stop Disrupts Flights

Airlines scrambled to restore normal operations across the United States on Saturday morning after a four‑hour nationwide FAA ground stop on Friday caused thousands of flight delays and cancellations.

By 11 a.m. ET on Saturday, more than 4,000 flights destined for, arriving from, or departing the United States had been canceled, according to FlightAware—an increase from the more than 8,000 cancellations recorded on Friday.

The prolonged ground stop, the longest nationwide FAA shutdown in 25 years, left passengers stranded at airports nationwide, uncertain about when they could resume travel.

Transportation Secretary Sean Duffy announced Saturday morning that flights were “slowly returning to normal,” but cautioned that passengers should anticipate continued delays and cancellations as airlines reschedule services and relocate aircraft and crews to where they are needed.

Later that day, Duffy gave additional details about the Friday disruption, explaining that the problem originated when a contractor performed routine maintenance at a remote FAA site to convert telecommunications lines from copper to fiber‑optic cable.

“We are trying to determine whether the issue stemmed from incompetence or from a faulty router installation,” Duffy said.

He added that once the maintenance work at the remote site was isolated, all systems came back online and the ground stop was lifted.

FAA Administrator Bryan Bedford apologized to passengers during the briefing, stating that he believed the worst of the disruption was now behind them.

“We will still experience delays and cancellations today, but this will enable a full recovery tomorrow,” Bedford said. “According to our airline partners, they expect to restore full schedule integrity by the end of the business day on Sunday.”

“I want to stress again: there is no evidence of any malicious intent, nor any indication of AI involvement,” he said. “We are clear that this is an equipment failure, and we are investigating the defective component.”

On Friday, Duffy had attributed the ground stop to an aging air traffic control system, noting that its communications equipment was overloaded with data and began producing inconsistent information.

“Consequently, we shut the system down,” Duffy said.

Homeland Security Secretary Markwayne Mullin said there was “no indication, as of now,” that the communications failure resulted from a malicious attack.

Duffy warned that it would take time to resume normal operations.

Among those impacted were sports teams traveling for weekend games. In college football, the Southeastern Conference announced that Mississippi’s game against Oklahoma was moved to Sunday, a day typically reserved for the NFL.

A men’s college basketball game between the University of North Carolina Greensboro and Cornell University, originally set for Saturday, was postponed, and NBA and NHL travel was also disrupted over the weekend.

Saturday morning saw reported flight disruptions at major airports in Boston, Washington, D.C., New York, and Miami.

American Airlines issued a statement Saturday, saying that although it was taking every possible step to minimize impact on customers and staff, the lingering effects of the major national airspace disruption would continue today, resulting in additional delays and cancellations.

Delta Air Lines warned travelers on Saturday that they should expect delays and further schedule adjustments as the airline works to reposition crews and aircraft following the FAA‑ordered ground stop.

The UK Civil Aviation Authority also released a statement Saturday morning, noting that while US flights have resumed, further disruptions may occur as airlines rebook affected passengers and restore normal services.

This was the third nationwide FAA ground stop this century; the first occurred after the September 11, 2001 terrorist attacks, and the second took place in January 2023 under the Biden administration when a pilot notification system failed.

During Friday’s briefing, Trump administration officials urged Congress—still controlled by Republican allies until January—to fully fund the construction of a completely new air traffic control system.

On Saturday, New York Governor Kathy Hochul, a Democrat, called for Duffy’s resignation and urged Congress to launch a full investigation into what went wrong to prevent a recurrence.
