A technical issue forced United Airlines to ground flights nationwide on Wednesday night, resulting in over 1,000 delays and more than 200 cancellations. 

According to The Associated Press, a United spokesperson said the issue was caused by a problem with the airline's weight and balance computer system, which started at around 6 p.m. ET and was resolved after a few hours.

Impacted travelers were reimbursed for meals and hotels during the delays.

“We are working with customers to get them to their destinations after a technology disruption on Wednesday evening,” United said in a statement on Wednesday. "The underlying technology issue has been resolved, and, while we expect residual delays, our team is working to restore our normal operations.”

The issues have carried over into Thursday as well, with over 140 flights delayed so far and another 150 canceled, according to FlightAware.com.

“Due to a technology issue, we are holding United mainline flights at their departure airports,” United’s statement continued. “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.”

The Federal Aviation Administration (FAA) and U.S. Transportation Secretary Sean Duffy both said they were aware of the technical issues impacting flights. They believe the glitch was not related to the broader air traffic control system nor a cyberattack.
