American Airlines has grounded all of its flights in the US due to unspecified technical issues, disrupting travel at the start of a busy Christmas Eve. The airline is suffering a massive system outage according to multiple travelers on X who are facing delays, which is reportedly preventing boarding passes from being scanned and flights from departing.
