WASHINGTON--Air travel across the United States is expected to return to normal by Sunday evening following a nationwide grounding of flights that disrupted thousands of departures, stranded passengers and caused widespread delays across the aviation network.
Federal Aviation Administration (FAA) Administrator Bryan Bedford said Saturday that the aviation system was recovering from Friday's unprecedented disruption, which forced authorities to suspend departures nationwide for more than four hours.
The shutdown resulted in thousands of flight cancellations and delays, with airlines scrambling to reposition aircraft, reorganize flight crews and accommodate stranded passengers.
According to flight-tracking data cited by Reuters, nearly 10,000 flights were canceled Friday, with thousands more delayed. The disruption continued Saturday as airlines canceled approximately 4,500 additional flights and reported thousands of delays.
The FAA attributed the shutdown to a telecommunications failure affecting air traffic control operations. Federal officials explained that the installation of new technology into the existing system overloaded older equipment, resulting in intermittent communications failures and radar disruptions.
US Transportation Secretary Sean Duffy said investigators were examining whether a newly installed router or an installation error caused the failure. The equipment was being installed as part of a broader modernization effort involving contractor L3Harris Technologies.
Officials indicated that the problems affected 17 of the country's 22 en route air traffic control centers, although none experienced a complete loss of communications.
The disruption forced authorities to halt departing aircraft as a precautionary safety measure. More than 3,000 aircraft already airborne were permitted to continue their journeys and landed safely.
Federal officials said there was no evidence that the incident resulted from a cyberattack.
Although the nationwide ground stop was lifted Friday evening, the consequences continued throughout Saturday, with airports experiencing congestion and airlines struggling to restore their normal schedules.
PJIA issues travel advisory
Princess Juliana International Airport issued its own travel update Saturday, confirming that the FAA's nationwide ground stop had been lifted and that airlines were working to resume their normal flight schedules.
The airport cautioned, however, that passengers could still encounter delays or schedule adjustments as airlines work to restore operations.
PJIA encouraged all passengers traveling through St. Maarten to check directly with their respective airlines for the latest flight information before heading to the airport.
The airport also thanked travelers for their patience and understanding as airline operations gradually return to normal.
The advisory is particularly relevant for St. Maarten, which maintains significant air connections with major American cities and relies heavily on the US market for tourism arrivals. Disruptions at American airports can affect connecting flights, aircraft availability and passenger movements throughout the Caribbean, even after the initial problem has been resolved.
PJIA did not indicate how many flights serving St. Maarten had been directly affected by the nationwide disruption.
Questions over aging aviation infrastructure
The incident has renewed concerns about the condition of America's air traffic control infrastructure and the urgency of replacing aging systems.
The US government has already committed billions of dollars toward modernization, but transportation officials are seeking additional funding to complete the overhaul.
Despite the disruption, federal aviation officials expressed confidence that airline operations would largely normalize by the end of Sunday, ahead of the busy Thanksgiving travel period.
Travelers departing from or arriving in St. Maarten on flights connected to the United States are encouraged to monitor airline notifications and verify their flight status before traveling to Princess Juliana International Airport.
