Storms sweeping across the eastern half of the country are disrupting air travel across the United States. FlightAware reported more than 3,500 flights canceled Monday and about 6,300 others delayed. The storms already dumped heavy snow across parts of the Midwest and were moving toward the East Coast with strong winds and the threat of tornadoes. The travel disruptions come during a busy period for airports, with spring break vacations and fans traveling for March Madness games. Meanwhile, a partial government shutdown affecting the Transportation Security Administration has stretched staffing at some airport security checkpoints, leading to longer lines in some places.
