DENVER (KDVR) — Commercial airline United Airlines ordered a ground stop for flights at multiple major airports Wednesday evening.
According to the ground stop alert posted by the Federal Aviation Administration, the carrier had asked for the ground stop to be issued due to a technology issue, but didn’t specify the cause.
“Due to a technology issue, we are holding United mainline flights at their departure airports. 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,” a United Airlines spokesperson told Nexstar’s KDVR in a statement on Wednesday night.
The airline provided an updated statement about the matter at about 8:15 p.m. MDT:
“We are working with customers to get them to their destinations after a technology disruption on Wednesday evening. The underlying technology issue has been resolved, and, while we expect residual delays, our team is working to restore our normal operations.”

“We’re aware United experienced a technology issue disrupting their operations. Some delays may continue as they work through the recovery process,” the FAA posted. “We’ve offered full support to help address their flight backlog and remain in close contact with United.”
