United Airlines Grounds All U.S. Flights Until Further Notice

United Airlines was forced to issue a ground stop for all flights nationwide due to a technical issue with its weight and balance computer system on Wednesday evening. 

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

The airline clarified that any flight already in the air would not be affected by the stop.
