The Federal Aviation Administration (FAA) implemented ground delay programs at Seattle-Tacoma International Airport and San Diego International Airport on September 26, 2026, due to runway restrictions and high traffic volume limiting airport capacity.
Seattle’s program resulted from runway, taxiway, and construction constraints, including the closure of Runway 16C/34C, which is scheduled to remain closed through November 15. The FAA added Seattle-Tacoma Airport to its national operations plan because of these infrastructure limitations.
San Diego International Airport’s ground delay program stemmed from its high traffic volume and reliance on a single commercial runway, reducing operational flexibility during peak periods.
Runway Closures and Delay Durations
At Seattle,
the ground delay program held inbound flights to meter arrivals amid construction impacts. The FAA cancelled the program once runway and taxiway conditions improved, allowing airlines to disregard prior departure time restrictions for Seattle-bound flights. Delays at Seattle currently range up to 15 minutes for gate holds and taxi times, with similar airborne delay levels reported.
San Diego continues to experience gate-hold and taxi delays between 15 and 29 minutes due to ongoing traffic volume exceeding single-runway capacity. Arrival delays at San Diego generally remain under 15 minutes, with trends showing a gradual reduction in delays following FAA advisories.
Flight Management and Traveler Information
The
FAA ground delay programs assign controlled departure times tailored to individual flights based on schedules, origin airports, and anticipated arrival demand to prevent congestion at these airports. Not all flights experience delays equal to airport-wide figures as individual assignments vary.
Travelers at both Seattle-Tacoma and San Diego International Airports face varying delay durations and should refer to their airlines for flight-specific status updates. The reported delay figures reflect overall airport operating conditions, not precise wait times for individual flights.
Airport Operations Status
No airport closures or broad suspensions of commercial airline service occurred at either Seattle-Tacoma or San Diego International Airport during this
period. Flight operations continue despite ground delay measures designed to manage reduced capacity.
Seattle’s ground delay program cancellation indicates restored capacity to manage normal traffic flows, while San Diego’s ongoing delays respond to peak traffic with gradual improvement expected as operations stabilize.
