Over 700 US flights canceled Saturday amid severe weather

With severe storms forecast to impact much of the central United States and multiple likely tornadoes, airlines began canceling flights Friday.

More than 750 flights were canceled in the U.S. at about 3:30 p.m. ET, according to the flight-tracking website FlightAware. Almost 5,300 were delayed.

Delta Air Lines led with the most cancellations, scrapping 323 flights, or 11% of its schedule.

Some airlines also began issuing waivers to give travelers flexibility.

The Department of Transportation has a series of dashboards to help travelers see what they're entitled to in the event their flight is canceled or delayed. In most cases, a canceled flight allows you to get a full refund, but delay compensation is a little less strict from a regulatory standpoint.
