SAN DIEGO — Afternoon travelers at San Diego International Airport face minor delays Monday as peak flight traffic strains the facility's single runway.
Federal Aviation Administration data shows an active ground delay program holding inbound flights at their departure airports, averaging 22 minutes behind schedule. On the ground at SAN, departing flights face taxi backups between 16 and 30 minutes due to compacted traffic demand.
Weather is not a factor. San Diego sits under clear skies at 84 degrees with light 9 mph winds and 10 miles of visibility.

What This Means
San Diego operates the busiest single-runway commercial airport in the United States. When scheduled arrivals cluster during peak travel windows, controllers must space traffic out, quickly backing up the pipeline. Up to 623 flights across the day may feel the ripple.
The delays do not exist in a vacuum. San Francisco International Airport (SFO) is running its own ground delay program, degrading roughly 9% of inbound traffic feeding into San Diego.
Based on BTS data, San Diego averages a 75.8% on-time rate over the last six months, with delays stretching to 57 minutes when operations fall behind. Today's 22-minute slowdown is modest by historical standards, but it creates tight squeezes for passengers with short connections.
What To Do
- Track your specific tail number: Use your airline's mobile app to see where your incoming plane is arriving from. If it is coming from San Francisco, anticipate potential departure creep.
- Do not delay your trip to the terminal: Average ground delays under 30 minutes can evaporate quickly if controllers find spacing gaps. Arrive at the airport according to your normal schedule.
- Protect your connections: If you booked a connecting flight out of San Diego with a layover under 45 minutes, check alternative flights now in case your incoming leg slips.

Outlook
Without storm systems or wind shifts threatening Southern California, operations will clear once the afternoon departure push winds down. Expect metered arrivals and taxi delays to persist until the evening traffic volume subsides.
