U.S. flight operations resume after massive nationwide ground stop

United States flight operations are gradually returning to normal following a nationwide ground stop caused by technical failures. The Federal Aviation Administration issued a nationwide ground stop for all U.S. flights on Friday, November 14, 2026. This disruption lasted approximately four hours and ended around 8:15 p.m. ET. The incident was described as the most extensive disruption to air travel in 25 years.

Technical failures trigger ground stop

The nationwide ground stop was triggered by technical problems involving radar and telecommunications systems. Specifically, data inconsistency in routers and switches caused the disruption. One report indicated that routers were overloaded with data, leading to this inconsistency. The Federal Aviation Administration expects airlines to recover full schedules before the close of Sunday, November 16, 2026.

The scale of the disruption was significant for travelers. On Friday, 600 flights were diverted, including 104 flights sent to other airports. Approximately 11,000 flights were scheduled to depart U.S. airports after 4 p.m. ET on Friday. For Saturday, 41,000 flights were scheduled. By Saturday night, 6,400 flights had been cancelled. Total cancellations across Friday and Saturday reached 12,500, according to reports from ABC News and FlightAware. Other reports indicated that 1.5 million passengers were affected by the grounding.

Safety and recovery efforts

Transportation Secretary Sean Duffy stated on the morning of Saturday, November 15, 2026, that flight operations are slowly returning to normal and it is safe to fly. Secretary Sean Duffy noted that the top priority is ensuring travelers get home safely to their families. The administration is currently coordinating with airlines to support the recovery process, though delays and cancellations are expected to continue.

While most operations are stabilizing, a collision occurred on the night of Saturday, November 15, 2026, at Miami International Airport. A Copa Airlines Boeing 737 and a UPS Boeing 767 collided on a taxiway. This specific incident was reported by infobae.com.

Funding for air traffic control

The recent technical failure has prompted calls for increased investment in aviation infrastructure. Secretary Sean Duffy requested $50 billion to update the air traffic control system. This figure represents a significant increase from a previous $30 billion request made by Secretary Sean Duffy and President Donald Trump. The Federal Aviation Administration aims to normalize all operations before the upcoming Thanksgiving travel period.
