American Airlines had the highest number of delayed flights on November
11, totaling 205. Southwest Airlines followed with 149 delayed flights. United Airlines and SkyWest Airlines reported 117 and 112 delayed flights, respectively, based on the mid-afternoon snapshot.
Earlier Fog and FAA Ground Stops
Earlier in the week, San Francisco International faced fog-related FAA ground stops on Monday, November 9, resulting in 187 delays and three cancellations by late morning due to dense fog and low clouds. These restrictions likely contributed to subsequent delays at connecting hubs including Chicago, Los Angeles, Seattle, and Atlanta.
Veterans Day Travel Impact and Passenger Guidance
November 11 was Veterans Day, a travel-heavy midweek day with increased passenger volumes leading to busier airport operations. The cause of the November
11 delays and cancellations was not confirmed by the FAA or airlines by the time of reporting. Federal Aviation Administration policies require airlines to refund passengers for canceled flights if they opt not to travel, including cancellations due to weather.
Travelers are advised to monitor live updates on flight status through FlightAware’s cancellations and delays page and their respective airline’s mobile app for the latest information on disruptions.
