United Airlines briefly grounded its fleet nationwide, the airline and Federal Aviation Administration said Tuesday.

The FAA confirmed to NBC News the airline had asked for the ground stop.

“We are experiencing a systemwide technology issue and are holding all aircraft at their departure airports,” United Airlines told CNBC in a statement.

“Flights that are already airborne are continuing to their destination as planned. We’re currently investigating and will share more information as it becomes available.”

The FAA said in a statement on X, formerly Twitter, at about 1:50 p.m. ET, that the airline lifted the ground stop for flights in the United States and Canada.

About the same time, the airline said in a statement the ground stop is now lifted.

In a subsequent statement, United Airlines said, “We have identified a fix for the technology issue and flights have resumed. We’re working with impacted customers to help them reach their destinations as soon as possible.”

It’s not the first time this year technological problems grounded commercial airlines in the United States.

In January, departures for all U.S. flights were halted for several hours after the Federal Aviation Administration experienced a computer outage.

The FAA said at the time the delays that affected thousands of flights appeared to have been caused by an issue in the Notice to Air Missions system, or NOTAM, which provides pilots with pertinent information they need to fly.

In June, the FAA ordered a ground stop to D.C.-area airports because of problems with a communication system at a facility that controls air traffic in Virginia. Less than an hour after stopping departures, flights to the area airports resumed, the FAA said.
