U.S. airlines recorded 1,104 flight delays and 66 cancellations on November 11, 2026, as of 1:57 p.m. Eastern Time. These disruptions affected flights within, into, and out of the country nationwide.
Airports and Airlines Leading Delays
San Francisco International Airport registered the highest number of delays on November 11 with 115. Chicago O’Hare ranked second with 92 delays, followed by Los Angeles International Airport with 81, Atlanta Airport with 61, Seattle-Tacoma Airport with 54, and Phoenix Airport with 51 delays by mid-afternoon.
American Airlines experienced the most flight delays of any carrier on the day, with 205 delayed flights. Southwest Airlines followed with 149 delays,
United Airlines with 117, and SkyWest Airlines with 112.
Earlier in the week on November 9, dense fog and FAA ground stops contributed to delays in the Bay Area, causing 187 delays and three cancellations at San Francisco-area airports by late morning. That weather disruption contributed to operational challenges at the hub.
Veterans Day and Travel Volume Impact
November 11, 2026, was Veterans Day, a holiday that typically increases airport traffic and air travel volume. The increased passenger flow on this holiday likely contributed to the delays and cancellations observed on this midweek day.
Passengers affected by canceled flights retain their right to refunds regardless of
whether weather conditions caused the cancellations. Delay and cancellation counts reported here are as of mid-afternoon and may have increased later in the day.
Delay Propagation and Causes
Delays originating at major hubs such as San Francisco International Airport commonly ripple through the national flight network, affecting connecting flights at other busy airports including Chicago O’Hare, Los Angeles, Seattle-Tacoma, and Atlanta.
There is no confirmed explanation for the total delays and cancellations on November 11 beyond previously noted weather disruptions earlier in the week. Aviation sources have not identified additional factors linked to these mid-afternoon figures.
