The Federal Aviation Administration issued an advisory to the public of the problem, and passengers were told to contact Delta for updates.
"Delta teams are expeditiously working to fix a systems outage that has resulted in departure delays for flights on the ground," the airline said in a statement. "Flights in the air remain unaffected. Delta apologizes to customers for the inconvenience."
The FAA said on its website that international flights were not affected due to "automation issues."
