The outage began at around 2:30 a.m., but limited flights had resumed by 8 a.m.

The first flight out of Milwaukee, scheduled for 5:30 a.m., did not take off as planned.
Long lines were seen at the Delta ticket counter as passengers tried to check in for their flights.
Ticket agents were forced to do manual check ins for 3 hours, which takes significantly longer.
"Hopefully I'll get out some time today. I'm only going home, I don't have a connecting flight, if I had a connecting flight I'd be a lot more worried about it," said Thea Murphy, who's headed to Boston.
Tani Flowers was thinking about just getting a hotel. "I'm heading to Idaho and I have 3 connecting flights. I don't think I'm going to make them all," she says.
Airline data company Flightaware said there were at least 858 cancellations and 7,359 delays across the global industry on Monday morning. It's unclear how many are related to Delta's problems and whether Delta's groundings are reflected in the numbers.
