"Delta Air Lines is experiencing a network outage affecting operations at the McNamara Terminal," Wayne County Airport Authority officials said in a statement on the airport's website. "Delta has initiated a ground stop for its flights while the airline works to resolve the issue."

A winter storm in the Midwest and Great Lakes prompted cancellation of more than 1,000 flights nationwide on one of the year's busiest travel days.

Detroit Metro said the airline is experiencing a network outage on Dec. 5 and grounded flights at the airport.

Delta Air Lines flights at Detroit Metro Airport (DTW) are now under a “ground delay,” with most flights delayed about 2 hours and 40 minutes.
