After all United Airlines’ departures were stopped across the U.S. on the day after Labor Day, flights resumed as the airline fixed a “technology issue.”

Shortly after 1:30 p.m., United sent out an alert of a nationwide ground stop.

“We are experiencing a systemwide technology issue and are holding all aircraft at their departure airports,” United tweeted. “Flights that are already airborne are continuing to their destination as planned.

“We will share more information as it becomes available,” the airline added. “Thank you for your patience as we work on a resolution to get you on your way as soon as possible.”

United asked the Federal Aviation Administration to pause the airline’s departures nationwide, according to the FAA.

Then less than a hour later, United lifted the ground stop for the U.S. and Canada.

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

The ground stop lasted for less than an hour, resulting in “no big impacts,” according to a spokesperson for Massport at Boston Logan International Airport.

According to the website FlightAware, more than 100 flight delays had been reported at Boston Logan as of 2:30 p.m. on Tuesday. Eight of those delays were United flights, while 32 of the delays were JetBlue flights.
