United Airlines Grounds Domestic Flights Due to Computer Outage

United Airlines was forced to ground all of its domestic mainline flights Sunday night due to a computer issue.

“A ground stop is in place for domestic flights due to an IT issue. We’re working on a resolution. We apologize for the inconvenience,” the airline said on Twitter at approximately 8 p.m. Eastern Time.

The airline said that the issue is not affecting international flights or those to or from Alaska and Hawaii.

Officials told Frequent Business Traveler that the problem had to do with its Aircraft Communications Addressing and Reporting System, known as ACARS.

ACARS is a system that sends and receives messages between planes that are in the air and an airline’s operations team.

Sunday’s failure isn’t the first time United has had computer issues that resulted in delayed or cancelled flights, although other instances had to do with the airline’s reservations and customer service systems. In October, the Chicago-based airline was forced to delay hundreds of flights under similar circumstances, and the airline had several headline-making system failures shortly after it consolidated its IT systems with those of Continental Airlines following the airlines’ merger.

United, however, isn’t alone with respect to IT woes. In September, British Airways passengers faced long delays and lines at airports across the globe and in August, Delta Air Lines suffered a major computer failure that caused the cancellation of approximately 2,000 flights.
