Delta Air Lines has resumed operations after briefly halting domestic departures Tuesday evening due to a "technology issue," the company said.

The second-largest U.S. airline had issued a ground stop for about an hour for U.S. flights, which prevented planes from departing Tuesday night. It said at time there had "been no disruption or safety issue with any Delta flight currently in the air."

International and regional carriers that fly for the airline weren't affected, and its app and website were still up and running, the airline said Tuesday.

As of Wednesday morning, flight-tracking site Flight Aware showed three Delta flights had been canceled.

The incident was relatively minor compared with longer and costlier outages that have hit Delta and its competitors.

A half-day power outage last December at Delta's hub at Hartsfield-Jackson Atlanta International Airport caused the airline to call off more than 1,400 flights, an event that coupled with a winter snowstorm Delta said cost it about $60 million.

An August 2016 computer outage prompted Delta to cancel more than 2,000 flights, standing thousands of travelers over several days. Less than a month earlier, Southwest Airlines canceled some 2,300 flights after a computer problem hit largest carrier of passengers within the U.S.

United Airlines grounded flights worldwide in July 2015 after a computer outage.
