All United Airlines flights were temporarily grounded on Wednesday because of “automation issues”, according to the US Federal Aviation Administration.
Flights were grounded at all airports and all facilities nationwide for more than an hour. Residual delays were expected throughout the day.
Before the advisory was announced, travellers had posted complaints about flight delays.
“We are recovering from a network connectivity issue this morning and restoring regular flight operations,” United said in an emailed statement. “We will have a waiver available at united.com for customers who are able to change their flight plans.”

Denver international airport advised passengers on United to allow extra time for their flights “as airline works to restore computer issues”. Washington Dulles international airport also said that United “is experiencing computerized system issues”.
United Airlines said it serves 235 domestic airports and has 4,935 daily departures. United Airlines also temporarily grounded flights because of automation issues in early June.
