San Diego International Airport sees 166 delays and 7 cancellations

Disruption overview

A major disruption at San Diego International Airport on 23 June 2026 left passengers dealing with 166 delays and 7 cancellations after nationwide air-traffic restrictions collided with the airport's single-runway limits. Southwest, Alaska, JetBlue, American, United, SkyWest, and Horizon Air were all affected, with disruption spreading to routes connected to Los Angeles, San Francisco, Dallas/Fort Worth, and Denver.

If you were caught up in the disruption, compensation is unlikely because the main cause was outside the airlines' control. Even so, canceled passengers should still be able to ask for a cash refund if they choose not to travel, and airlines should provide rebooking and basic care during longer waits.

Disruption details

Travel through San Diego International Airport was heavily disrupted on 23 June 2026 after nationwide air-traffic restrictions collided with the airport's single-runway limits. By the time of publication, 166 flights were delayed and 7 were canceled as operations at SAN came under intense pressure.

For passengers, this meant long gate holds, missed connections, and crowded rebooking lines, with thousands stranded in Terminals 1 and 2. The disruption began during the busy summer travel period and quickly spread beyond San Diego, with knock-on delays reported on routes linked to Los Angeles, San Francisco, Dallas/Fort Worth, and Denver.

Several airlines were already dealing with serious disruption at SAN:

• Southwest Airlines had 35% of its schedule delayed, although no cancellations had been logged so far.

• Alaska Airlines recorded a 22% delay rate and 2 cancellations.

• JetBlue logged a 20% delay rate and 2 cancellations.

• American Airlines showed a 28% delay rate and 1 cancellation.

• United Airlines had an 11% delay rate without cancellations.

• SkyWest Airlines posted a 10% delay rate and 2 cancellations, while Horizon Air services were also affected.

Southwest Airlines was hit hardest overall because it is SAN's largest operator. Even without outright cancellations, that level of delay can still leave you facing late departures, missed onward connections, and aircraft arriving too late to keep the next part of the day's schedule on time.

The main cause appears to be a combination of national air-space flow restrictions on 23 June and SAN's limited ability to recover once flights start slipping. San Diego International Airport operates the busiest single-runway field in the United States, which means one late-arriving aircraft can quickly disrupt a tightly packed bank of departures.

That pressure has been harder to absorb because major West Coast hubs have also been dealing with rolling congestion. With fewer recovery gaps in the schedule, airlines have struggled to stop local delays in San Diego from spilling into their wider domestic networks across the U.S. West and Mountain West.

Carriers are now trying to work through a growing aircraft-rotation backlog while repositioning aircraft and crews. Airport and airline officials haven't given an exact timeline for when the backlog will clear, and residual delays could continue for several days while operations are brought back into shape.

If you're flying in or out of SAN, it's worth checking your airline's app before heading to the airport. When schedules are this tight, delay updates, gate changes, and rebooking options can shift quickly.

If your flight was one of the 7 cancellations and you decide not to travel, U.S. rules mean you should be able to request a cash refund. If you're staying on your itinerary, rebooking space may be limited while airlines work through the disruption during a high-demand period.

Because the root cause here was air-traffic control restrictions rather than an airline-controlled problem, compensation is unlikely. Even so, that doesn't mean you're without support. Your airline should still help with rebooking or refunds, and provide care such as food, refreshments, or accommodation if your delay becomes long enough.
