International flights were not grounded due to this computer issue. The ground stop for domestic flights was initially scheduled to end at 8 p.m., but then the airline tweeted saying it's "working on a resolution," according to NBC News.
The FAA then reportedly extended the ground stop to 9 p.m. EST.
Angry passengers quickly expressed their frustration on social media Sunday night.
United faced a similar situation in October when the company experienced an issue with its weight reporting system. In that instance, passengers were delayed for hours as well.
