Federal Aviation Administration chief Bryan Bedford says US air travel will return to normal by Sunday evening following a nationwide ground stop that led to over 19,000 flight cancellations.

NEW YORK: US air travel was expected to return to normal on Sunday after a nationwide ground stop left hundreds of thousands of passengers in limbo and disrupted travel worldwide.

The Trump administration blamed Friday’s ground stop — meaning no planes can take off — on a botched replacement of old copper wire communication lines.

Federal Aviation Administration (FAA) chief Bryan Bedford said that 12,000 flights were canceled on Friday, while tracking website FlightAware showed more than 6,600 canceled flights on Saturday.
