Aug. 6 (UPI) -- United Airlines on Wednesday night briefly suspended flight departures nationwide because of a technology issue and expected further flight delays throughout the night.

Shortly after 7 p.m. CDT, the airline reported an outage and one hour later the system was coming back up, CBS News reported.

"Due to a technology issue, we are holding United mainline flights at their departure airports," United said in a statement obtained by ABC News. "We expect additional flight delays this evening as we work through this issue. Safety is our top priority, and we'll work with our customers to get them to their destinations."
