A tech outage led United Airlines to ground flights nationwide Wednesday night, and even with the issue now resolved, over 1,000 flights were delayed and dozens were canceled.
"We are working with customers to get them to their destinations after a technology disruption on Wednesday evening," the airline said in a statement.
The outage stemmed from an issue with the airline's weight and balance computer system, United said.
"The underlying technology issue has been resolved,
and, while we expect residual delays, our team is working to restore our normal operations," the airline said.
The airline said the outage began shortly after 6 p.m. ET and was resolved after a few hours.
"Due to a technology issue, we are holding United mainline flights at their departure airports," the airline said in a statement. "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."
