TL;DR
US airlines worked to clear a backlog after a rare nationwide ground stop on Friday, with delays and cancellations continuing Saturday and into Sunday. FAA Administrator Bryan Bedford expected carriers to resume full schedules by the end of the weekend, but officials had not determined whether contractor error or equipment failure caused the communications outage.
US air travel was slowly recovering Saturday after a rare nationwide ground stop the previous day, but airlines were still managing widespread delays and cancellations as the Federal Aviation Administration investigated the communications outage behind the disruption. FAA Administrator Bryan Bedford said he expected carriers to resume full schedules by the end of the weekend; the cause of the outage had not been established.

Airlines spent Saturday rerouting stranded passengers, rearranging crew schedules and clearing delayed flights. FlightAware data cited by CNN showed more than 8,000 US flights delayed and more than 6,000 canceled during the day in one report. A separate snapshot in CNN’s coverage put Saturday cancellations above 6,200 and delays above 7,700, reflecting figures reported at different times. Early Sunday, the tracker showed nearly 600 delays and more than 1,000 cancellations; later figures in the report listed at least 760 Sunday cancellations and 200 delays already recorded.
Transportation Secretary Sean Duffy said upgrade work at a remote FAA location was underway on an aging communications system, including replacing copper wire with fiber. He said the outage likely stemmed from that work, but the administration had not determined whether human error, contractor mistakes or equipment failure caused it. Duffy criticized L3Harris, the contractor involved in the upgrade. The company said it was supporting the FAA’s investigation.
The disruption extended beyond airlines. Princess Cruises delayed departures for three ships scheduled to leave US ports Saturday so passengers could reach the ports, while Carnival Cruise Line also pushed back some departure times, according to company statements reported by CNN. Princess said the delays would not affect the ships’ itineraries.
How the Outage Affected Travelers
The ground stop disrupted travel across the country, leaving passengers to contend with missed connections, cancellations and uncertain departure times even after flights resumed. The figures reported on Saturday show the scale of the backlog, while the continued cancellations into Sunday suggest that restoring normal operations takes longer than lifting a ground stop: aircraft and crews must be repositioned and schedules rebuilt.
The incident also puts attention on the reliability of the FAA’s communications infrastructure and how modernization work is managed. The outage’s cause remains under investigation, so its implications for contractor oversight and system upgrades are not yet settled. Meanwhile, the dispute over additional funding could shape how lawmakers evaluate the agency’s plans to update air traffic control.

The FAA Upgrade Under Scrutiny
According to Duffy, the work involved replacing copper wire with fiber at one remote FAA location on an aging communications system. That account links the outage to upgrade activity but does not establish precisely how the failure occurred. The Trump administration had not offered a detailed explanation in the reporting, and the FAA investigation was ongoing.
House Transportation Committee ranking member Rick Larsen and Aviation Subcommittee ranking member André Carson questioned the administration’s request for an additional $30 billion for air traffic control upgrades. They said Congress approved $12.5 billion in June 2025 and questioned why more funding was needed, citing their assertion that only $1 billion of that allocation had been spent. FAA and Transportation Department officials were scheduled to brief congressional staff Monday, with Bedford expected to appear at a hearing by early December.
New York Gov. Kathy Hochul called for Duffy to resign or be removed. The White House characterized her demand as a political move. President Donald Trump was receiving regular updates, a White House official told CNN, but had not commented publicly.
“He expects airlines to resume full schedules by the end of the weekend.”

Cause and Recovery Remain Unsettled
Investigators had not determined whether the outage resulted from contractor error, a faulty component or another problem during the upgrade work. Duffy’s comments described a possible link to the project but did not amount to a final finding. L3Harris said it was assisting the investigation.
It also remained unclear when each airline would return to its full schedule. Bedford’s end-of-weekend forecast was an expectation, not a guarantee, and the flight totals in CNN’s coverage varied by report and timestamp. Passengers should check directly with their airline for current flight status and rebooking information.
Investigations and Briefings Ahead
Airlines were expected to continue clearing the backlog through Sunday, while the FAA investigated the communications failure. FAA and Transportation Department staff were scheduled to brief congressional staff on Monday about the administration’s funding request. Larsen and Carson also said they expected Bedford to answer questions at a hearing by early December.
Those steps may provide more detail on the upgrade work, the outage’s cause and the status of air traffic control modernization spending. Until officials release findings and airlines confirm schedules have stabilized, the extent and duration of remaining disruption will depend on recovery efforts and new operational updates.
Key Questions
What caused the nationwide ground stop?
The cause had not been confirmed. Duffy said the outage likely stemmed from upgrade work on an aging FAA communications system, but investigators had not determined whether human error, contractor mistakes or equipment failure was responsible.
When were flights expected to return to normal?
FAA Administrator Bryan Bedford said he expected airlines to resume full schedules by the end of the weekend. That was a forecast, and cancellations and delays were still being reported into Sunday.
How many flights were affected?
CNN cited FlightAware figures showing more than 8,000 delays and more than 6,000 cancellations in the United States on Saturday in one snapshot. Other figures in the report, taken at different times, listed more than 7,700 delays and over 6,200 cancellations. Counts continued to change.
What is L3Harris’s role in the investigation?
L3Harris was the contractor involved in the communications-system upgrade. Duffy publicly criticized the company but said the cause was still unclear. L3Harris said it was supporting the FAA’s investigation.
What happens next in the funding debate?
FAA and Transportation Department officials were scheduled to brief congressional staff Monday on the administration’s request for an additional $30 billion for air traffic control upgrades. House Democrats also said they expected FAA Administrator Bryan Bedford to appear at a hearing by early December.
