American Airlines passengers faced significant delays on Christmas Eve after a technical glitch grounded all flights across the U.S. However, the issue appears to have been resolved, with travelers reporting that boarding has resumed.

The nationwide ground stop, which lasted about an hour, caused widespread disruptions, leaving passengers with substantial travel time to recover. The Federal Aviation Administration (FAA) currently shows no major delays at U.S. airports, but the full impact remains to be seen.

On the East Coast, a clipper system has added to travel concerns, bringing snow and winter weather to the region. Meanwhile, the West Coast is contending with a bomb cyclone, which has unleashed heavy rain, mountain snow, and high winds, further complicating holiday travel plans.

With weather challenges compounding earlier delays, it’s shaping up to be a less-than-merry Christmas for many travelers across the country.
