San Francisco International Airport experienced widespread disruptions on October 10, 2026, as 457 flights were delayed and 8 flights canceled. The delays, averaging 57 minutes with some lasting up to 10 hours, occurred under a Federal Aviation Administration (FAA) ground delay program imposed for the entire day through 11:59 p.m. Flight disruptions affected both arrivals and departures at the airport during the opening day of San Francisco’s Fleet Week air shows.
Causes of Flight Restrictions
The FAA attributed the ground delay program to air traffic control staffing constraints and adjustments to airport operations related to the Fleet Week event. Staffing shortages limited the number
of aircraft that could be safely managed, prompting the FAA to regulate the flow of inbound flights. Projected aircraft arrival rates during the ground delay period ranged from 36 to 45 per hour. The program aimed to hold flights at their departure airports to prevent congestion at San Francisco International Airport.
Blue Angels Demonstration and Weather Impact
The Navy Blue Angels began their aerial demonstration shortly before 4 p.m. over San Francisco Bay but curtailed the routine due to fog reducing visibility. Poor weather conditions affected the opening day performances of the Fleet Week air show, which features military and civilian aircraft flying along the San
Francisco waterfront. The air shows are scheduled to continue on October 11 and 12, with Blue Angels performances planned for both afternoons.
Traveler Impact and FAA Advisories
Passengers at San Francisco International Airport faced flight delays of up to 10 hours on October 10, 2026. The FAA issued advisories identifying staffing constraints as the cause of the delays and noting operational changes following the afternoon air show. Both arriving and departing flights experienced disruptions. Travelers were advised to monitor their flight status directly with airlines for updated departure and arrival times.
