American Airlines grounds all US flights on Christmas Eve due to technical glitch

American Airlines has grounded all its flights in the U.S. on Christmas Eve due to an unknown technical glitch. The airline is working to resolve the issue but has not provided a timeline for when flights will resume. Passengers have reported delays, with many flights stuck on the runway and returning to the gate. The airline has advised customers to address ticketing and transfer issues through its channels. This incident follows previous disruptions in the airline industry, including a major outage affecting multiple carriers earlier this year and a significant system failure at Southwest Airlines two years ago.
