Passengers booked on an American Airlines flight from Charlotte Douglas International Airport (CLT) to Chicago O’Hare International Airport (ORD) endured an unusually difficult journey after a series of operational setbacks left them in the wrong city.

Having already been delayed taking off by more than seven hours, the Chicago-bound flight AA836 ended up diverting to Minneapolis-St. Paul International Airport (MSP) due to thunderstorms in the Chicago area. It then spent hours on the ground at MSP before eventually leaving for Chicago, with its passengers arriving at their destination almost 11 hours late.

Rough Day For American Airlines Passengers And Crew

As first flagged by Flightradar24, flight AA836’s problems began before the aircraft had even left the ground. Initially scheduled for a 1:05 PM departure, the flight did not take off from Charlotte until 8:27 PM, almost seven-and-a-half hours past its scheduled departure. Flight tracking data shows the flight — operated by an Airbus A321neo — attempted to avoid storm cells in the region by routing around them on its way to ORD.

However, as it was nearing Chicago, the decision was made to divert to Minneapolis for safety reasons. O’Hare has experienced difficult weather so far this summer, and Friday was one of its worst days in recent memory, with ground stops issued at both O’Hare and Chicago Midway (MDW). Thunderstorms and powerful winds led to hundreds of flight cancellations and delays, having a significant impact on American and United Airlines, which both operate hubs at O’Hare.

The passengers on flight AA836 eventually touched down in Minneapolis at 10:08 PM and would spend another two hours on the ground before taking off again. The onward flight, operated by the same aircraft, departed MSP just after 00:15 AM, finally landing in Chicago at 01:22 AM. With an original scheduled arrival of 2:40 PM, this represented a delay of almost 11 hours. Simple Flying contacted American Airlines for comment on this incident, but a representative could not be reached before publication.

Over 600 Cancelations And 1,000 Delays At O’Hare

Data from FlightAware shows there were over 600 inbound and outbound cancellations at O’Hare yesterday, as well as over 1,000 delayed flights. This left around 20% of scheduled flights canceled and almost 40% of flights delayed. American was able to minimize its outright cancellations, registering fewer than 50 canceled flights on Friday. However, across its network, over 1,000 American flights were delayed on Friday, the majority at O’Hare.

O’Hare’s status as one of the busiest hubs in the US has made it vulnerable to operational shocks. The airport ranks as the busiest in the world as measured by flight movements, recording a total of 857,392 takeoffs and landings in 2025. This pushed it ahead of Hartsfield-Jackson Atlanta International Airport (ATL) for the first time since 2019, although ATL is still the world’s busiest by total passenger count.

American had hoped to significantly expand its ORD operation this year as part of its infamous “turf war” with United, aiming for over 500 daily departures from O’Hare. However, the Federal Aviation Administration (FAA) has introduced a cap of up to 2,800 daily flight movements.

Disruption During Record Holiday Weekend

Friday’s long-delayed and diverted flight occurred during one of the US’ busiest travel periods around the Fourth of July holiday season. The Transportation Security Administration (TSA) has projected it will screen nearly 18.7 million passengers at US airports between June 30 and July 6, with Thursday, July 2, the single busiest day of the holiday travel rush at more than three million air travelers.

This also coincides with the ongoing 2026 FIFA World Cup, which has seen an influx of international travelers, and the America 250 celebrations marking the country’s 250th anniversary of independence. As a result, airline resources can often be stretched as they cope with elevated demand.
