US airline company Delta Airlines says all its departing flights have been suspended due to a nationwide system outage.
“Customers should check the status of their flight before heading to the airport while the issue is being addressed,” the company tweeted.
It said it was working to resolve the problem as soon as possible. Inbound flights en route are not affected.
Delta serves nearly 180 million customers a year, employing over 80,000 people, according to its website.
It has its headquarters in Atlanta, Georgia and began in the 1920s as a crop-dusting company.
