Airlines with the Highest Number of Delayed Flights

United Airlines had 117 delays, and regional carrier SkyWest Airlines accounted for 112 delayed departures and arrivals during the same period.
Factors Contributing to Travel Disruptions
No confirmed cause for the delays and cancellations on November 11 was available from the sources reviewed. However, earlier in the week, San Francisco faced fog-related Federal Aviation Administration ground stops on Monday, November 9, causing 187 delays and three cancellations. This slowdown likely contributed to cascading delays at hub
airports including Chicago, Los Angeles, Seattle, and Atlanta. Additionally, Veterans Day travel on November 11 increased passenger volume, as many travelers extended their weekends, resulting in busier airports than a normal midweek day.
Traveler Information and Refund Rights
Flight delay and cancellation numbers continued to change throughout the day on November 11. Passengers were advised to monitor live updates through FlightAware’s cancellations and delays page and airline apps. Federal regulations mandate airlines to provide refunds for cancelled flights if passengers opt not to travel, regardless of whether weather conditions caused the cancellations.
The cause of the 66 flight cancellations on November 11 remains unspecified, and
no detailed information was provided regarding ongoing FAA procedures or weather conditions at the time of reporting.
