Storms disrupt 4,662 flights across Atlanta, Dallas/Fort Worth, and Chicago O'Hare

Disruption overview

Severe spring thunderstorms and air-traffic-control restrictions caused 4,173 delays and 489 cancellations across the US airline network on 29 April 2026, with Hartsfield-Jackson Atlanta International Airport, Dallas/Fort Worth International Airport, and Chicago O'Hare International Airport hit hardest. Delta Air Lines recorded the most delays, while American Airlines led cancellations as weather and flow restrictions at Chicago O'Hare and Dallas/Fort Worth spread through the national schedule. If your journey was affected, it's understandable to feel frustrated. Because this disruption was caused by weather and air-traffic-control limits outside the airline's control, EC 261 compensation is generally unlikely on EU-covered routes, but airlines should still provide rebooking or refunds, care, and overnight accommodation where needed.

Disruption details

Severe spring thunderstorms and air-traffic-control restrictions disrupted flights across the United States on 29 April 2026, causing 4,173 delays and 489 cancellations by late afternoon. The worst disruption was centered on Hartsfield-Jackson Atlanta International Airport, Dallas/Fort Worth International Airport, and Chicago O'Hare International Airport. For passengers, this meant missed connections, long waits, and a stressful day of travel uncertainty.

The biggest pressure points were Chicago O'Hare International Airport and Dallas/Fort Worth International Airport. The Federal Aviation Administration ordered ground-delay programs at Chicago O'Hare after thunderstorm activity repeatedly closed arrival corridors, while a separate storm cell over North Texas reduced capacity at Dallas/Fort Worth. When two major hubs slow down at the same time, delays don't stay local for long.

The heaviest airport disruption was reported at:

• Hartsfield-Jackson Atlanta International Airport: 1,199 delays and 42 cancellations.

• Dallas/Fort Worth International Airport: 437 delays and 283 cancellations, the highest cancellation total in the country.

• Chicago O'Hare International Airport: 318 delays and 110 cancellations.

• Dallas Love Field: 143 delays and 25 cancellations.

• Phoenix Sky Harbor International Airport: 165 delays and 14 cancellations.

• Harry Reid International Airport: 102 delays and 7 cancellations.

• Austin-Bergstrom International Airport: 74 delays and 9 cancellations.

Airlines across the network were affected. Delta Air Lines recorded the highest delay volume with 1,093 delays and 41 cancellations. American Airlines led cancellations with 209 canceled flights and 526 delays, with Dallas/Fort Worth feeling the impact especially hard. Southwest Airlines, SkyWest Airlines, United Airlines, Envoy Air, PSA Airlines, Endeavor Air, and Alaska Airlines were also caught up in the disruption.

This kind of disruption snowballs quickly. The slowdown at Chicago O'Hare International Airport created crew rotation and aircraft positioning problems that rippled into Atlanta, while the storm-related restrictions at Dallas/Fort Worth International Airport disrupted American's connecting schedule across the country. In simple terms, when aircraft and crews arrive late at major hubs, the next set of departures often slips with them.

By Wednesday evening, thousands of passengers were still stuck in terminals at Atlanta and Dallas/Fort Worth, facing long customer-service lines and tight hotel availability. Airlines were trimming flights, rerouting crews, and using their apps and websites to handle mass rebooking. Recovery is expected to take 24 to 48 hours as aircraft and staff are moved back into position.

Further schedule changes were still possible overnight as storm cells continued moving east. That means you could feel the knock-on effects even if your departure airport wasn't seeing bad weather itself, especially if your aircraft or crew was due to arrive from one of the affected hubs.

For passengers on trans-Atlantic or other EU-covered trips, compensation under EC 261 is generally unlikely here because the disruption was driven by weather and mandatory air-traffic-control restrictions outside the airline's control. Even so, you still have rights. If your flight was canceled, your airline should offer rerouting or a refund, and during long waits it should provide care such as food, refreshments, and accommodation if you're stranded overnight.

Although compensation is unlikely in this situation, that doesn't mean you're without support. Your airline should still help with rebooking, refunds where relevant, and basic care while you wait.
