Thousands of people were stranded Monday after Delta Air Lines flights were grounded due to a system outage.
The airline tweeted that its systems were “down everywhere.”
“Due to a computer outage, flights awaiting departure are currently delayed," it said, adding that flights en route were operating normally.
It advised travelers to check the status of their flights before heading to the airport.
Delta said it serves nearly 180 million customers annually, employs more than 80,000 people around the world and operates more than 800 aircraft.
