Severe Storms Cause 5,500+ Flight Delays Across U.S.

Widespread severe weather disrupted air travel across the United States on Wednesday, leading to more than 5,500 flight delays and hundreds of cancellations as powerful thunderstorms swept through the Midwest and heavy rainfall affected parts of the South.

According to FlightAware data, 5,250 flight delays and 356 cancellations had been recorded by 7:30 p.m. EDT on Wednesday. Some of the nation’s busiest airports experienced significant operational disruptions as weather conditions deteriorated throughout the day.

Chicago O’Hare International Airport was among the hardest-hit hubs. More than half of its departing flights were either delayed or canceled by Wednesday evening, while 42% of arriving flights experienced delays. The National Weather Service reported wind gusts reaching up to 30 mph in the Chicago area, with showers and thunderstorms expected before 10 p.m. EDT. A flash flood warning was also in effect south of the city.

Dallas Fort Worth International Airport reported 179 delayed departures and 134 delayed arrivals, while Minneapolis-Saint Paul International Airport logged nearly 150 outbound delays and 123 inbound delays. Hartsfield-Jackson Atlanta International Airport also faced disruptions, with approximately 20% of both arriving and departing flights delayed.

Forecasters said Tropical Storm Arthur, the first named tropical storm of the year, is expected to bring additional heavy rainfall to Gulf Coast states in the coming days. The National Weather Service warned that tropical-storm-force winds are likely to continue across southeastern Texas and southwestern Louisiana. Rainfall totals of 5 to 10 inches are forecast along much of the Texas coastline and portions of Louisiana, Mississippi, Alabama, western Georgia, and Florida’s Panhandle.

Although airlines are generally not required to provide compensation or accommodations when weather causes travel disruptions, several major carriers have introduced travel waivers for affected passengers. Delta Air Lines is allowing customers scheduled to fly on Wednesday or Thursday to modify travel plans without additional fees. American Airlines has issued similar waivers for travelers booked on Wednesday, while United Airlines and Southwest Airlines have also offered flexible travel options for passengers impacted by the severe weather.
