UA spokeswoman Maddie King said that, they had issued a ground stop for all domestic mainline flights due to an IT issue. She also added that, they are working as quickly as possible to resolve the issue to get their customers to their final destinations. United has apologized to their customers for the inconvenience.
There has been no acknowledgement of how many flights were cancelled or delayed. The ground stop lasted approximately two hours, and flights resumed around 9.15 p.m. EST.
The system outage was an issue for planes that had yet to depart, as pilots need this information to safely take off. Planes already in the air were in no danger, United Airlines sources said. The issue did not affect communications between planes and air traffic control.
United flies an average of 4,500 flights per day. Mainline flights are those operated by United itself, not its regional partners or subsidiaries.
This is the second time in three months that United has been forced to ground its fleet after a computer glitch, though, to be fair, other airlines have suffered through technological issues that have resulted in major delays and cancellations – Southwest and Delta in August, and British Airways in September.
