Hurricane Debby Disrupts 4,000 Flights And Counting

This story was updated at 11 a.m. Eastern Time.

Monday is shaping up to be a frustrating day for air travelers, as Hurricane Debby made landfall on Florida’s northeastern coast as a category 1 storm with winds of 80 m.p.h. and heavy downpours. Authorities say feet of rainfall are possible from Florida to North Carolina.

The U.S. air travel system is already seeing the impact. As of 11 a.m. Eastern on Monday, there are more than 1,500 flight cancellations and 2,500 delays in and out of U.S. airports for the day, according to FlightAware, a free app that provides flight tracking data. But based on an historical trend analysis, more cancellations will come closer to departure times.

Three of the “Big Four” U.S. airlines — American, Southwest and Delta — account for more than 760 flight cancellations and 1,000 delays on Monday. The fourth, United Airlines, is less impacted.

At nine Florida airports, more than 20% of flights on Monday have been canceled. More than 200 flights have been canceled in and out of Orlando and Tampa airports collectively.

The Department of Transportation requires all airlines to offer customers a refund if their flights are canceled or significantly delayed due to reasons within the airline’s control. But that rule does not pertain to weather-related delays and cancellations.
