FAA Raises SFO Arrival Cap. Will Delays Ease August 12?

San Francisco International Airport is getting a measured capacity lift today. The Federal Aviation Administration is raising the airport’s maximum hourly arrivals to 40 aircraft starting August 12, 2026, by introducing staggered parallel approaches on the east-west runways.

That change will not restore full side-by-side dual approaches, but it is the first official step up from the 36-arrival cap that tightened SFO during runway rehabilitation and summer fog. Travelers still need buffers, yet the airport’s own spokesman called the move a step in the right direction.

What the FAA is changing on August 12

SFGATE’s August 8 Routes column reported an FAA email stating that arrivals can increase to 40 aircraft per hour starting August 12, with plans to raise the hourly maximum to 42 by the end of the month. The agency said it will accomplish the increase by introducing staggered parallel arrivals on the airport’s east-west runways, keeping one airplane ahead of the other for safety.

Earlier this year, during the same week runway rehabilitation began, the FAA cut the dual-approach arrival maximum to 36 aircraft per hour. That cut, layered on seasonal fog and construction, pushed delay rates higher. SFO spokesman Doug Yakel told SFGATE that about a third of flights were delayed 15 minutes or more after the regulation and runway work began, compared with about one-fifth in the prior year. Specialist coverage such as The Points Guy on SFO summer delays and United relief expectations has tracked the same rough summer reliability story travelers have felt on Bay Area banks.

Yakel said the FAA is revising its restriction on staggered parallel landings on August 12. “While this will not fully restore the arrival rate we had when true side-by-side landings were permitted, this is nonetheless a step in the right direction,” he said in the SFGATE report.

Deep Arrival’s earlier coverage of SFO runway construction delays through October focused on the construction window and delay risk. This post is about the dated FAA rate increase that starts August 12 and the staged path to 42 arrivals later in the month.

What travelers should change in their plans

Keep a connection buffer at SFO even after the rate rises. A move from 36 to 40 arrivals per hour is real capacity, not a full reopen of unconstrained dual approaches. Missed international banks can still happen when fog returns or ground delays stack.

If you hold a same-day domestic-to-international connection, prefer a longer pad than you would use at a clear-weather hub. Rebooking desks get busiest when several waves of arrivals slip together.

Airlines may still publish weather or construction advisories for the Bay Area even as the FAA rate improves. Check your carrier app the morning of travel for ground delay programs, gate changes, and rebooking windows that sit outside the FAA’s hourly arrival number.

Travelers planning city time after landing can use Deep Arrival’s guide to things to do in San Francisco only after they confirm the actual arrival. A late gate does not erase a ferry or museum ticket if you leave enough slack.

United and other major carriers that concentrate banks at SFO should see some schedule reliability improvement as the arrival rate rises, but construction through early October still caps how clean the day can look. Plan the rest of the summer as better, not normal.

How this fits the runway project timeline

SFGATE reports the runway construction project is on pace to finish by October 3, 2026. That date remains the broader finish line for the physical work that forced the tighter approach rules.

The August 12 rate change is an air-traffic procedure change, not the end of construction. Expect continued taxiway and runway complex complexity even as hourly arrivals climb.

A later move to 42 arrivals per hour by the end of August is the next milestone to watch. It is a plan, not yet the live number, so treat 40 as the confirmed step and 42 as the next FAA target to reconfirm later this month.

If your trip is after early October, the construction pressure should ease further once the rehabilitation finishes, provided the FAA keeps the higher approach rates in place. Recheck airport notices before you lock tight connections for fall travel.

What a higher arrival rate does not automatically fix

Ground congestion, taxiway bottlenecks, and terminal staffing still matter after an aircraft lands. A smoother approach stream can still end in a long taxi or a late gate if the airport complex is saturated.

United and other hubs that schedule tight turns at SFO should benefit first when arrivals stabilize, but a single missed outbound push can still cascade. If your itinerary depends on a short turn to make a Europe or Asia bank, keep the same defensive pad you used in July.

Weather remains the wild card. Marine layer and low visibility procedures can force spacing that undercuts the theoretical hourly number even when the FAA authorizes 40 arrivals. Check the morning forecast and the airline app together, not just the construction calendar.

Baggage delivery and rental car counters can lag when many delayed banks clear at once. If you need a same-day drive to Napa or a peninsula meeting, leave more curb time than the flight schedule alone suggests.

For August trips, build the connection pad as if SFO is improving but not cured. The FAA’s 40-arrival rate is progress you can plan around, as long as you keep the residual construction and fog risk on the same checklist.
