Ground stop, ahead of the busy Christmas travel, had threatened the holiday plans of thousands

American Airlines on Tuesday lifted an hour-long ground stop of all its flights in the US due to an unspecified technical issue, a notice on the US aviation regulator's website showed.

American Airlines flights arriving and departing Cincinnati/Northern Kentucky international airport showed short delays Tuesday morning, but it's unclear if those are tied to this technical issue or something else.
