United Airlines recorded the highest number of flight cancellations worldwide on Friday, July 3, 2026, following Federal Aviation Administration (FAA) ground stops and ground delays at Chicago O’Hare International Airport (ORD), the airline’s largest hub.
Chicago O’Hare Sees Massive Disruptions
ORD faced more than 600 flight cancellations and over 1,000 arrival and departure delays, according to flight-tracking site FlightAware. The FAA imposed ground stops throughout the day due to severe thunderstorms and tornado warnings affecting the Chicago area.
American Airlines flight 836, scheduled from Charlotte, North Carolina, to Chicago, departed 7.5 hours late before being diverted to Minneapolis, Minnesota, following storm activity near ORD, as
reported by FlightRadar24. Diverted flights also brought passengers to Kansas International Airport (MCI), which accommodated travelers originally bound for Chicago.
United Airlines canceled approximately 4% of its flights on July 3 and delayed nearly one-third, making it the most disrupted major airline globally that day. Regional carriers SkyWest and GoJet Airlines, operating under United Express, experienced significant operational delays and cancellations as well.
Weather Worsens Into July 4, Affecting Flights and Airports
Severe weather persisted into the early hours of July 4, with the U.S. National Weather Service issuing flood warnings and advisories for Chicago. Up to 2.5 inches of rainfall was recorded during the storms. FlightAware data as
of early July 4 showed 16 canceled and 49 delayed departures at ORD, alongside 86 canceled and 60 delayed arrivals.
United Airlines continued to experience extensive disruption at ORD on July 4, with 85 canceled and 57 delayed flights reported early in the day. AccuWeather forecasted continued thunderstorms fueled by a heat dome over the central and eastern United States through the Independence Day weekend. This weather pattern is expected to affect multiple airports, including Orlando International Airport (MCO) and Miami International Airport (MIA), with potential tropical system development along the southern Atlantic to Gulf Coast.
Baggage Delays and Customs Hold Passengers at Orlando
On June 27, approximately
800 passengers at Orlando International Airport experienced delays exceeding five hours at baggage claim. Passenger Carol Wick claimed a Virgin Atlantic employee warned travelers they could be arrested if they left U.S. Customs without their bags, but Virgin Atlantic and the Greater Orlando Aviation Authority (GOAA) denied these allegations.
The U.S. Customs and Border Protection (CBP) clarified that the delays stemmed from extended baggage wait times affecting customs entry processing. CBP affirmed it holds full jurisdiction over customs enforcement and stated all passengers, baggage, and merchandise arriving in the United States are subject to inspection.
Passenger Rights and Airline Policies During Weather Disruptions
United Airlines and other major
carriers issue weather waivers during severe disruptions, allowing travelers to change flights without fees or cancel for travel credits. United’s waivers offer options including free rebooking within the waiver window and cancellation for United eCredits but not cash refunds.
The U.S. Department of Transportation (DOT) emphasized that airlines do not guarantee schedules and have no legal obligation to compensate or provide amenities such as meals or hotel accommodations when weather causes delays or cancellations. The DOT encourages passengers to request assistance for meals or calls, noting some airlines may choose not to provide amenities if disruptions stem from uncontrollable events
like weather.
Passengers faced long waits on the tarmac at ORD. One Reddit user reported being delayed on the tarmac for over two hours before returning to the gate with departure pushed to 7 a.m. Another traveler reported their United flight cancellation extending until the following morning despite waiting on the tarmac for hours.
