United Airlines resumes US flights after temporary grounding on technical issue

United Airlines Holdings Inc. suffered a temporary grounding of its aircraft nationwide due to an unspecified equipment outage, but the airline resumed flights at US airports in a little over an hour.

The Chicago-based carrier requested the grounding for its main operation and subsidiaries on Tuesday after its aircraft were unable to contact flight dispatchers using normal means, according to a posting on the Federal Aviation Administration’s website.

The FAA confirmed in an email to Bloomberg the airline had asked it to pause departures nationwide, but declined further comment.
