Southwest Airlines is facing legal action after being accused by U.S. authorities of illegally operating chronically delayed flights and disrupting passengers’ travel. The U.S. Transportation Department alleged that the airline operated unrealistic schedules. Transportation Secretary Pete Buttigieg said: “Today’s action sends a message to all airlines that the department is prepared to go to court in order to enforce passenger protections.” The carrier said in response: “In 2024, Southwest led the industry by completing more than 99% of its flights without cancellation.” At this time it remains unclear whether the lawsuit will be pursued by the incoming administration of President-elect Donald Trump.
