DALLAS — The federal government is fining American Airlines $4.1 million for dozens of instances in which passengers were kept on board planes without a chance to exit during long ground delays.

The U.S. Department of Transportation said Monday it is the largest such fine against an airline since rules covering long ground delays took effect about a decade ago.
