Delta was briefly forced to ground its flights from Minneapolis-St. Paul International Airport Tuesday evening because of a "technology issue."
The airline imposed an hour-long ground-stop on its U.S. mainline flights after a tech glitch impacted some of its systems.
Delta issued a statement at 8:28 p.m. that confirmed the problem, before an update at 9:20 p.m. said the issue had been resolved and staff were working to get flights underway again.
It nonetheless meant delays for evening travelers at MSP Airport, while some delays have continued into Wednesday morning, albeit Delta says the impact should be "minimal."
No flights were canceled as a result of the glitch, which Delta is now investigating to find the root cause.
"The technology issue’s impact was limited to the U.S.," Delta said. "There was no safety impact on any Delta flights."
"We apologize to all customers for this inconvenience."
Delta is the biggest carrier at MSP Airport, which is one of its major American hubs, flying to more than 120 destinations from the Twin Cities.
