TL;DR
Airlines were gradually restoring operations after a rare nationwide ground stop on Friday, but delays and cancellations continued on Saturday and into Sunday. Transportation Secretary Sean Duffy linked the outage to upgrade work on an aging FAA communications system, while the cause and responsibility remained undetermined.
U.S. airlines were gradually restoring service on Saturday after a rare nationwide ground stop on Friday, but widespread cancellations and delays continued as carriers worked to reposition crews and clear stranded passengers. FAA Administrator Bryan Bedford said he expected airlines to resume full schedules by the end of the weekend, while officials had not determined what caused the communications outage behind the stoppage.

The disruption left airlines managing a substantial backlog. FlightAware data cited in the report showed more than 8,000 U.S. flights delayed Saturday and more than 6,000 canceled during the day. By early Sunday, the tracker showed nearly 600 delays and more than 1,000 cancellations. Figures varied across updates as the day progressed; the report also cited a later snapshot of more than 6,200 Saturday cancellations and at least 760 Sunday cancellations.
Transportation Secretary Sean Duffy said work was underway at a remote FAA location to replace copper wire with fiber on an aging communications system. He said the outage likely stemmed from the upgrade work but that it was not clear whether human error by the contractor or equipment failure was responsible. Duffy criticized L3Harris, the contractor involved, saying he was “stuck with L3Harris.” The company said it was supporting the FAA investigation.
The effects extended beyond air travel. Princess Cruises delayed departures for three ships leaving U.S. ports on Saturday to give passengers more time to reach port, and said the delays would not affect their itineraries. Carnival Cruise Line also pushed back some Saturday departure times, according to a company spokesperson cited by CNN.
Backlogs Reach Beyond Airports
The disruption affected travelers whose flights were canceled or delayed, as well as airline crews and passengers trying to connect to later services. Even as more flights operated on time and Sunday cancellations eased in some updates, the scale of Saturday’s disruption meant that the recovery depended on airlines reassigning aircraft and crews as well as getting individual flights moving again.
Delays to cruise departures show how an aviation outage can affect travel plans beyond airports. The incident also puts attention on the reliability of FAA communications infrastructure: the system supports air traffic operations, but officials had not yet established how the outage occurred or whether the upgrade work directly caused it.

The Outage and Funding Dispute
The nationwide ground stop occurred Friday, November 13. The report describes it as rare and says airlines spent Saturday rerouting passengers, adjusting crew schedules and working through the resulting backlog. The FAA administrator’s expectation of a return to full schedules by the end of the weekend was a forecast, not confirmation that all flights would be back to normal.
The investigation unfolded alongside a dispute over funding for air traffic control upgrades. House Transportation Committee ranking member Rick Larsen and Aviation Subcommittee ranking member André Carson questioned the administration’s request for an additional $30 billion. They said Congress approved $12.5 billion in June 2025 and questioned why the administration needed more, arguing that only $1 billion of that earlier amount had been spent. Those spending figures and the case for additional funding were raised by the lawmakers and had not been independently resolved in the report.
FAA and Transportation Department officials were scheduled to brief congressional staff on Monday. Larsen and Carson also said they expected to hear from Bedford at an early-December hearing. New York Gov. Kathy Hochul called for Duffy to resign or be removed; the White House dismissed her demand as a political maneuver. President Donald Trump was receiving regular updates, according to a White House official, but had not commented publicly.
“He expects airlines to resume full schedules by the end of the weekend.”

Cause and Recovery Still Unsettled
Investigators had not established whether the communications outage resulted from contractor error, a malfunctioning piece of equipment, or another factor. Duffy’s comments about the upgrade work and possible contractor mistakes were not a final finding, and L3Harris’s statement did not address what caused the outage.
It was also not yet clear whether the FAA’s investigation would identify specific technical failures, how quickly the remaining backlog would be cleared, or whether every carrier would meet Bedford’s weekend timetable. FlightAware counts in the report were time-sensitive snapshots and differed across updates, so they should not be read as a single final tally.
FAA Briefing and Flight Recovery
Airlines were expected to continue restoring schedules through the weekend, with travelers facing possible delays or cancellations while carriers worked through the backlog. Passengers should check directly with their airline for current flight status; the figures reported on Saturday and early Sunday may change as operations develop.
On Monday, FAA and Transportation Department officials were scheduled to brief congressional staff about the administration’s funding request and air traffic control upgrades. The investigation into Friday’s outage remained ongoing, with further details needed to determine the cause and any responsibility.
Key Questions
What caused the nationwide ground stop?
Officials had not confirmed the cause. Sean Duffy said the outage likely stemmed from work to upgrade an aging FAA communications system, but said it was unclear whether human error or equipment failure was responsible.
When were airlines expected to return to full schedules?
FAA Administrator Bryan Bedford said he expected airlines to resume full schedules by the end of the weekend. That was an expectation, and disruptions were still being reported in the updates.
How many flights were affected?
FlightAware figures cited in the report included more than 8,000 U.S. flight delays and more than 6,000 cancellations on Saturday. By early Sunday, the tracker showed nearly 600 delays and more than 1,000 cancellations. Counts varied between report updates and were changing over time.
What role did L3Harris have?
L3Harris was the contractor involved in the communications-system upgrade work described by Duffy. He suggested the contractor may have made mistakes, but no finding had established that the company caused the outage. L3Harris said it was supporting the FAA investigation.
Could the flight disruption affect cruise passengers?
Yes. Princess Cruises delayed departures for three ships on Saturday so passengers had more time to reach port, and Carnival Cruise Line also delayed some departures. Princess said the changes would not affect the ships’ itineraries.
