Severe summer storms on Tuesday, August 11, 2026, disrupted air travel at major U.S. hubs, including Chicago O’Hare International Airport (ORD), John F. Kennedy International Airport (JFK), and LaGuardia Airport (LGA). By 2 p.m. EDT, Chicago O’Hare reported more than 120 cancelled flights and upwards of 400 delays, while JFK and LaGuardia combined logged over 100 cancellations and more than 250 delayed flights as line storms and heavy rain passed through the region.
Airlines Implement Weather Waivers Amid Disruptions
American Airlines is waiving change fees and fare difference penalties for passengers traveling on August 11 through ORD or Northeast airports including JFK, LGA, and Newark Liberty
International Airport (EWR). This applies to tickets purchased by August 9, with rebooking allowed through August 13.
United Airlines is permitting fee-free rebooking for Chicago flights departing on August 11. Passengers may reschedule travel between August 9 and August 14 in the same cabin without paying a fare difference.
Delta Air Lines offers no-change-fee rebooking for flights through New York metro airports — JFK, LGA, EWR, and Westchester County Airport (HPN) — for tickets issued on or before August 10. Rescheduled travel can take place through August 13.
JetBlue is waiving change and cancellation fees and fare differences for flights
on August 10 and 11 touching JFK, LGA, EWR, HPN, Long Island MacArthur Airport (ISP), or Boston Logan International Airport (BOS). Rebooked travel can occur through August 15.
Travelers Urged to Use Online Tools for Flight Management
Passengers affected by the storm-related disruptions at ORD, JFK, LGA, and EWR are encouraged to use airline mobile applications or online portals to modify bookings ahead of arriving at airports. The severe weather conditions, including line storms and heavy rainfall, have contributed to widespread delays and cancellations at these hub airports.
The disruptions extend to secondary airports in the New York metro area, with fee waivers covering Westchester County, Long Island MacArthur,
and Boston Logan airports through several major U.S. carriers. Continued adverse weather through August 11 has stressed operations, requiring flexible scheduling and accommodations by airlines.
