Affected airlines canceled numerous flights and advised passengers to check for updates on their travel status. The ground stop impacted multiple regional centres, although it was lifted later in the evening.

San Francisco International Airport (SFO) also issued an update, confirming that Pacific-bound flights, including services to Hawaii and Asia, had been cleared to depart from the airport. It advised passengers to check directly with their airlines for the latest information.
The nationwide ground stop was lifted at 8:15 pm ET, according to Reuters.
Why did the FAA impose a nationwide ground stop?
The FAA grounded flights nationwide on Friday afternoon following communications problems at regional air traffic control centres, citing extraordinary circumstances and safety concerns.
Transportation Secretary Sean Duffy said the outage affected 22 regional centres responsible for directing aircraft travelling between airports across the country. FAA technicians were investigating the problem.
Homeland Security Secretary Markwayne Mullin said there was no indication that the disruption was the result of a deliberate attack, describing it as a telecommunications outage.
The incident marked the first nationwide ground stop since January 2023, when a malfunction in a key FAA computer system disrupted air travel. The previous such shutdown had followed the September 11, 2001, attacks.
Aviation safety expert Steve Arroyo said the outage appeared similar to a communications failure at a regional air traffic control centre in September, which disrupted hundreds of flights across the Northeast, but on a nationwide scale.
