Frustrated travelers experienced long waits at airports worldwide on Monday as Delta Airlines grounded all flights due to a computer system outage.
Delta's official Twitter account offered up a slew of apologies to annoyed fliers who tweeted their complaints to @Delta.
The tweets confirmed the outage but didn't give any estimate on when it would be resolved.
In a statement posted on the company's website this morning, Delta warned customers to check the status of their flights before heading to the airport.
"Delta has experienced a computer outage that has affected flights scheduled for this morning," the statement said. "Flights awaiting departure are currently delayed. Flights en route are operating normally. Delta is advising travelers to check the status of their flights this morning while the issue is being addressed."
