The American airline United Airlines on Tuesday, midday, suspended all takeoffs in the United States because of a computer problem that caused a slowdown in its systems. “A software update caused a mive slowdown in United’s technology systems earlier today,” she said in the afternoon.
“We briefly kept the planes” on the ground and “operations returned to normal around 12:45 GMT,” the company said.
“A widespread technological problem”
The incident lasted just over an hour and was not caused by a cybersecurity issue, according to a source familiar with the matter. At the end of the morning, the airline had announced the suspension of flights by mentioning a “generalized technological problem”, without further details. She had specified that the devices already in flight continued towards their destinations as planned.
The grounding was lifted around 6:00 p.m. GMT (8 p.m. in France). “We have found a solution to remedy the technological problem and the flights have resumed,” she said, without further details.

The American agency supervising aviation, the FAA, had made it known that the company had itself requested this suspension in the United States. In an information notice published at 4:33 p.m. GMT on its website, the FAA specified that this request was valid until 6:00 p.m. GMT and that it was due to “an equipment failure”. United Airlines shares ended Tuesday’s session on the New York Stock Exchange down $48.47.
