Washington:Air traffic is gradually resuming across the United States following a ground stop that resulted in the cancellation of more than 2,500 flights, leaving millions of passengers stranded.

According to Qatar News Agency, the Administrator of the Federal Aviation Administration (FAA), Bryan Bedford, stated that flight schedules across the US are expected to return to normal by the end of Sunday. However, airlines may still experience some delays and cancellations until normal operations are fully restored.

US Transportation Secretary Sean Duffy announced the resumption of air traffic operations during a press conference on Friday. He explained that new technologies integrated into the air traffic control system had strained ageing equipment, causing disruptions in communications and radar systems. This led authorities to order a four-hour suspension of flights.
