More than 10,000 US flights delayed or cancelled due to major storms

FAA halts flights at key East Coast and southern airports

More than 10,000 US flights were delayed or canceled Monday amid a series of storms affecting several major airports along the East Coast and some other locales.

Because of the risk of high winds and severe thunderstorms, the Federal Aviation Administration ordered delays at the New York City area's three airports - New York's LaGuardia and JFK and Newark airport in New Jersey - as well as at Reagan Washington National Airport, airports at Charlotte and Atlanta, and Houston's Bush airport.

Transportation Secretary Sean Duffy said the weather was impacting flights across the country. A major winter storm was also snarling flights across the Midwest and Great Lakes states.

The FAA earlier imposed ground stops at Reagan National, Chicago O'Hare and at Charlotte before lifting them.

FlightAware, a flight-tracking site, said more than 6,500 US flights had been delayed and more than 3,500 canceled as of 1:30 pm EDT (1730 GMT).

American Airlines, Southwest Airlines and Delta Air Lines all have about a third of flights delayed or canceled, according to FlightAware, while United Airlines has 25 percent of flights delayed or canceled.

About 40 percent of flights at Atlanta were canceled or delayed, a third at Chicago O'Hare and 50 percent at LaGuardia.

The US government ordered federal employees in the Washington area to leave offices by 2 pm (1800 GMT) because of weather risks.
