U.S. flights resumed Saturday after the Federal Aviation Administration halted flight departures across the country for more than four hours on Friday, leading to thousands of flight delays and cancellations.
The disruption is set to continue this weekend, even after the nationwide ground stop was lifted at 8:15 p.m. ET on Friday.
"The safety of the flying public is always the FAA's highest priority. The FAA lifted the ground stop and some flight departures are resuming," the agency said in a post on X on Saturday.
"Before clearing flights to resume, we thoroughly tested our systems to confirm they were stable and that operations remain reliable," it added.
There were more than 6,200 delays and more than 3,400 cancellations as of early Saturday, according to FlightAware.
