(AP Photo/Ted S. Warren, File) (Newser) – Delta Air Lines passengers around the world are beginning the week stuck in airports thanks to what the airline says is a global systems failure. "We are currently experiencing a major system-wide network outage," tweeted the airline, which was unable to say when the problem will be fixed. CNN reports that some passengers are stuck on the tarmac, while others are unable to check in or have missed connecting flights. "Delta is advising travelers to check the status of their flights this morning while the issue is being addressed," the airline said in a statement early Monday. A San Francisco-bound passenger at Heathrow tells NBC that airline employees are beginning to check passengers in manually but things are moving very slowly.
