Delta flights delayed worldwide due to 'computer outage'

A system-wide computer outage has delayed Delta flights around the world, leaving thousands of passengers stuck in airports as they wait to board their plane. The US airline hasn't said how long the glitch might take to fix, but advises passengers to "check the status of their flight before heading to the airport while the issue is being addressed." Flights already on their way to their destination are unaffected, says Delta.
