American Airlines requested a nationwide ground stop, which was later canceled, on the morning of Christmas Eve due to technical problems.

The airline announced a technical issue "with all American Airlines flights" - but the authorities say a national "groundstop" has now been lifted.

Technical issues hampered the airline’s operations on one of the busiest travel days of the year. Holiday travelers flying with American Airlines experienced widespread Christmas Eve disruptions on Tuesday after the Federal Aviation Administration (FAA) announced that the airline had grounded all of its flights nationwide.
