More than 1,400 flights have been canceled and more than 7,200 have been delayed as of 5:50 p.m. as severe storms continue to hammer regions of the U.S. with flash floods and tornado watches.
FlightAware, a service that tracks flights, states that it was Sunday ET. The busiest airports for flight delays are Boston Logan International Airport (BOS), John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), and Newark Liberty International Airport (EWR).
On Sunday morning, JFK posted on Twitter that there were flight-related delays and cancellations, advising customers to call their airline before flying. Airports in Boston, New York, Philadelphia, Washington, D.C., Florida, Atlanta, and Charlotte will have delays on Sunday due to slow-moving thunderstorms, the Federal Aviation Administration has told airline travelers.
In affected cities, many airlines began to provide waivers to assist travelers in rebooking their flights.
