With severe storms forecast to impact much of the central United States and multiple likely tornadoes, airlines began canceling flights Friday.
The death toll rose to 27 and more dangerous weather was forecast for a wide swath of the South and Midwest.
More than 670 flights were canceled in the U.S. at about 1:30 p.m. ET, according to the flight-tracking website FlightAware. Over 2,700 were delayed.
Delta Air Lines continued to lead with the most cancellations, scrapping 303 flights, or 9% 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.
American Airlines is offering a weather waiver for select Dallas-Fort Worth, Texas flights with an original travel date of April 2 can be rebooked through April 7. And for select Northeast U.S. flights scheduled to fly through April 3 can be rebooked through April 5.
