United Airlines Restarts Flights After Tech Glitch Disrupts Travel

United Airlines Faces Major Tech Outage, Disrupting Thousands of Flights

A significant technology issue caused a major disruption for United Airlines on Wednesday, leading to over 1,000 flight delays and dozens of cancellations across the United States. The airline confirmed that the problem has since been resolved, but the effects of the outage are still being felt as operations return to normal.

The outage began at 6:12 p.m. ET and was attributed to an issue with the airline’s weight and balance computer system, known as Unimatic. According to United Airlines, this technical glitch is unrelated to recent cybersecurity concerns in the aviation industry. However, the exact cause of the problem remains unclear.

“The underlying technology issue has been resolved, and while we expect residual delays, our team is working to restore our normal operations,” a United Airlines spokesperson said in a statement.

Flight data tracking service FlightAware reported that more than 1,000 flights were delayed and hundreds were canceled from Wednesday evening into Thursday morning. The Federal Aviation Administration (FAA) acknowledged the disruption, stating that United experienced a technology issue that affected its operations. The FAA added that some delays may continue as the airline works through the recovery process. The agency is assisting United in addressing the flight backlog and remains in close contact with the airline.

Several major airports across the country were impacted by the outage, including Chicago, Denver, Newark, Houston, and San Francisco. According to the FAA system status, United requested ground stops at about 7:30 p.m. ET, which contributed to the widespread disruptions.

Passengers faced significant challenges during the outage. Angela Jeffers, a passenger whose flight from Nashville to Denver was delayed by two hours, shared her experience. She said the pilot informed passengers that the airline was missing critical numbers needed for takeoff, leaving them without a clear estimate of when they would be able to depart.

Jeffers also mentioned that around 9:30 p.m. ET, passengers received an update that some flights had begun boarding. However, due to traffic congestion, not all flights could proceed immediately. United offered to cover the cost of a hotel and a flight for Jeffers the following day, as her original flight had not yet boarded.

Her sister, Jessica Jeffers, was also affected by the disruption, this time at the Denver airport. She described the situation as “pretty rough” and shared that she had been stuck on a plane for two hours waiting to fly to Newark. Passengers were given limited options—either deboard or stay on the plane with no clear direction on what would happen next. Additionally, the air conditioning on the plane was running at a low setting, making the environment uncomfortable for those on board.

Another traveler, Johan Kotze, was caught in the chaos at Louis Armstrong New Orleans International Airport. He was beginning a vacation to the Indian Ocean island nation of Mauritius when he encountered the delays. As a result, he likely missed connecting flights and had to rebook his travel arrangements, including a car and accommodation.

“It’s not very nice,” Kotze said of the experience, highlighting the frustration many travelers faced during the outage.

The incident underscores the complexity of modern airline operations and the potential ripple effects of even a single technological failure. While United Airlines has confirmed that the issue has been resolved, the impact on passengers and the broader aviation system will likely be felt for some time.

As the airline continues to work through the backlog of flights, travelers are advised to stay informed about their flight status and consider alternative travel plans if necessary. The event also raises questions about the reliability of critical systems in the aviation industry and the need for robust contingency measures.
