The FAA has announced a ground stop impacting all United Airlines flights destined for Chicago and numerous other major hubs around the U.S.
According to an alert on the FAA’s website, all United Airlines flights destined for Chicago have been halted at their departing airports.
Airports in Denver, Newark, Houston, and San Francisco are also impacted by the ground stops, according to the FAA.
In a statement to NBC Chicago, the company cites a “technology issue” behind the ground stop, and warns that additional delays are expected.
“Due to a technology issue, we are holding United mainline flights at their departure airports,” the company said. “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.”
O’Hare was packed with travelers Wednesday night as United flight delays mounted.
