The U.S. Federal Aviation Administration says normal U.S. air traffic operations are gradually resuming.
“Normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews,” the FAA said on its Twitter feed. “The ground stop has been lifted.”
The FAA suffered a “system outage” over night and, at one point, ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information.
The FAA supplies critical information to pilots and aviation officials across the U.S.
Air Canada said its transborder operations were being affected. “We are putting in place a goodwill policy for affected customers to change their travel plans,” an Air Canada official told Global News.
NBC News reports that United Airlines said it had temporarily delayed all domestic flights until at least 10 a.m., a move that caused massive headaches for mid-week travel across the U.S.
The website Flight Aware reports 4,314 airline delays in and out of the U.S. as of 7:50 a.m. today, and another 2,071 cancellations.
The latest cancellation woes come after a major meltdown from Southwest Airlines over the Christmas holidays.
