United Airlines grounds flights nationwide over technology issue
"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."
In an update, United said its systems are coming back online, but passengers can expect delays throughout the night on Wednesday. So far, 827 flights have been delayed and 23 have been canceled.
The airline confirmed in a statement to ABC News that it is not a cyberattack.
The ground stop does not affect United Express flights, and any flight that is already in the air will continue to its destination, according to the airline.
Multiple FAA notices have stated that the airline has requested ground stops at major hubs, including Newark, San Francisco, Chicago, Denver and Houston.

Some United Airlines flights are canceled or delayed as tech outage recovery continues
United Airlines is still recovering from a technology outage that temporarily grounded all of its flights Wednesday night, though the airline said it largely expects to run a normal schedule Thursday. A United spokesperson told USA TODAY in a statement that the airline was working to get customers to their destination amid residual delays and cancelations, but that the underlying technology issue had been resolved. According to FlightAware, which tracks airline delays and cancellations, United had canceled 154 flights as of 9:30 a.m. ET on Thursday, about 4% of its total schedule, with an additional 179 flights delayed. The airline said it is treating the service disruptions as "controllable," which in regulatory terms, means affected passengers are entitled to some protections and compensation from the airline. "We paid customer expenses such as hotels when applicable," a statement from the airline said. What you're entitled to if your flight is delayed or canceled If your flight is canceled for any reason you're entitled to a refund if you choose not to fly on alternative options offered by the airline, even if you originally purchased a nonrefundable ticket. When it comes to delays, the "controllable" versus "non-controllable" distinction that United made for the Wednesday outage is important. Airlines are on the hook for more accommodations if a disruption is considered to be within their control, as opposed to being caused by an external factor like weather. The Department of Transportation has a dashboard outlining its regulations and each airline's policies.

United Airlines tech issue that impacted more than 1,000 flights resolved, residual delays expected
A disruption to a system housing United Airlines' flight information that caused more than 1,000 delays has been resolved, but delays continued into Thursday. The impacted system, called Unimatic, houses flight information that is fed to other systems including those that calculate weight and balance and track flight times, according to United. It's not clear what caused the problem, which was resolved late Wednesday. While residual delays were expected, United said its team was working to restore normal operations. About 35% of all the airline's flights were delayed and another 7% were canceled Wednesday, according to FlightAware, a website that tracks flight disruptions. By midmorning Thursday, 5% of United flights for the day were delayed and 4% were canceled. FlightAware reported 43 cancellations at Chicago O'Hare by Thursday morning, including 42 United flights. An alert on the Federal Aviation Administration website Wednesday said all United flights destined for Chicago were halted at their departing airports. Flights to United hubs at Denver, Newark, Houston and San Francisco airports also were affected. The airline's travel alert page noted that a technology disruption might impact flights to or from several U.S. airports from Thursday to Sunday including Denver, Newark, Washington, Houston, New York, Los Angeles, Orlando, Chicago, San Francisco, Honolulu and Guam and some in Europe, such as London, Frankfurt and Munich. 'Safety is our top priority, and we'll work with our customers to get them to their destinations,' an emailed statement from the Chicago-based airline said. The system outage, as the company described it, lasted several hours, the statement said. It wasn't related to recent concerns about airline industry cybersecurity. United said it was treating it as a controllable delay, meaning it paid customer expenses such as hotels when applicable. In an interview, United Airlines passenger Benjamin Fuentes, who flew from Boston to Houston, told KTRK-TV that they were told that they would be waiting for a while after the plane landed. 'The first hour, people were already standing up and just walking around the cabin because there was nothing to do,' he said. 'I got on Netflix.' After about an hour, they were told that the system was down nationwide, he said. Eventually, they learned that they found a gate, but it took another 45 minutes before they got there, he said. The FAA said in a statement Thursday that it was aware of the disruption to United operations, noting that delays may continue as the airline recovers. 'We've offered full support to help address their flight backlog and remain in close contact with United,' the FAA said. United Airlines apologized on social media and said in some cases it would pay for hotel and other expenses incurred by travelers because of the delays. 'Hey there, we apologize for the travel disruption today,' the airline told a customer on the social platform X. 'Our teams are working to resolve the outage as quickly as possible. Thank you for your patience.'
