"Passengers in several cities say a massive computer outage has stranded United Airlines passengers at airports across the country," The Associated Press writes. "This is at least the third major computer outage for the Chicago-based airline since June."
The company tweets that, "We're aware of a computer issue affecting some of our flights. We're working to resolve it. We'll update as we have more details."
