SFO Travelers Face Months of Delays Under New FAA Order

Travelers passing through San Francisco International Airport are being warned to brace for longer waits after a new Federal Aviation Administration order sharply reduces the number of flights allowed to land each hour.

What the New FAA Limits Actually Do at SFO

The Federal Aviation Administration has issued a new order that lowers the maximum number of hourly arrivals at San Francisco International Airport from 54 to 36, according to recent coverage from national and Bay Area outlets. The change represents a roughly one-third cut in permitted landings during peak periods and is layered on top of an ongoing runway repaving project that was already constraining capacity.

Publicly available information indicates that airport managers had been operating under temporary construction-related limits that brought the previous cap down to about 45 arrivals per hour. The latest FAA decision tightens that further, setting a new ceiling that will remain in place while safety measures are reviewed and infrastructure work continues.

The order specifically targets how many aircraft can arrive at SFO in a given hour, rather than dictating which individual flights must be removed from schedules. Airlines and the airport are now working through schedule models to understand whether those constraints can be absorbed through delays and rerouting, or whether certain flights will ultimately be canceled or retimed.

Departures from SFO are not directly restricted by the new order, but industry schedules show that outbound flights are often affected when arriving aircraft and crews are delayed. As a result, the impact is expected to ripple in both directions for travelers using the airport as an origin, destination, or connection point.

Why the FAA Is Tightening Rules on Parallel Landings

At the core of the order is a longstanding operational feature at SFO: side by side approaches to closely spaced parallel runways. Aviation-focused reporting describes how arriving aircraft have historically landed simultaneously on runways separated by about 750 feet, a practice that allows high throughput in a crowded airspace but requires precise spacing and coordination.

Under the new rules, those closely spaced parallel approaches are more tightly limited, particularly in conditions where visibility or traffic complexity might heighten risk. Aviation safety analyses note that the Bay Area presents an unusually dense environment, with major airports in Oakland and San Jose, as well as several smaller fields, sharing overlapping arrival and departure paths.

The FAA order follows a series of widely covered runway and near-collision incidents at airports around the United States, including a recent fatal crash at New York’s LaGuardia Airport involving an Air Canada jet and an emergency vehicle. Reporting indicates that regulators have framed the SFO decision as a response to the specific geometry and complexity of the airport’s runways and airspace, rather than as part of a nationwide flight reduction program.

For travelers, the technical details translate into fewer aircraft being cleared to land at the same time. When schedules are built around higher arrival rates than the new rules permit, the excess flights are likely to be held in the air, metered further out along the approach, or shifted to off-peak times if airlines adjust their timetables.

How Much Delay Passengers Should Expect

San Francisco airport planners had already been forecasting disruptions tied to a six month repaving project that has taken a pair of north south runways out of service. Before the FAA’s latest move, public briefings suggested roughly 10 to 15 percent of flights could experience notable delays tied to the construction alone.

Local broadcast and newspaper coverage now cites updated airport estimates that about 25 percent of arriving flights may face delays of at least 30 minutes under the tightened FAA cap. That figure reflects the combination of reduced runway capacity and the lower arrival rate, and it is expected to vary by day depending on weather, time of day, and airline scheduling choices.

Early data points from major carriers at SFO show a mixed pattern. One large airline is reported to be reviewing its schedule for potential adjustments, while another has publicly indicated that delay counts have fluctuated from one day with more than a dozen late arrivals to another day with almost no disruption. Industry analysts note that as the construction phase and the FAA order settle in, patterns are likely to become clearer and schedules may be retimed to better fit the new constraints.

Travelers connecting through SFO on tightly timed itineraries may feel the changes first. When a quarter of inbound flights face half hour or longer delays, misconnected passengers, rebookings, and crews out of position can quickly create secondary congestion in terminals, even if most flights eventually operate.

Timeline, Scope, and Who Is Most Affected

The current repaving project on SFO’s north south runways is scheduled to last roughly six months, with airport communications pointing to early October as the target date for reopening. Once that work is complete, some arrival capacity is expected to return, but the separate FAA order on parallel approaches and overall arrival rates may continue to shape how many flights can land each hour.

United Airlines, which operates a large hub at SFO, is likely to see substantial operational effects because of its dense schedule of domestic and international flights. Alaska Airlines and several foreign carriers also rely on SFO as a key gateway. Public statements and industry commentary suggest that all of these airlines are analyzing how best to distribute flights across the day, including the possibility of shifting some services to less congested times.

The order applies specifically to arrivals at San Francisco International and does not directly affect neighboring Oakland or San Jose airports. However, because air traffic in the Bay Area is interdependent, any rerouting or added holding stacks around SFO can still influence flows for flights bound to or from the region as a whole.

Travel demand into the Bay Area remains strong, particularly for business travel and tech sector ties, making it unlikely that airlines will significantly pull back service in the short term. Instead, observers expect a period of operational fine tuning in which carriers test schedule changes, adjust block times, and potentially add connection buffers to protect long haul itineraries.

Practical Tips for Travelers Using SFO in the Coming Months

While airlines and regulators work through the effects of the new order, passengers have limited control over the operational side, but they can take steps to reduce the risk of serious disruption to their own plans. Consumer advocates point to time of day, connection windows, and route choices as key levers for travelers routing through SFO between now and the fall.

Morning flights are often more resilient to rolling delays because aircraft and crews are beginning their daily rotations, so early departures into and out of SFO may see fewer knock on effects from earlier disruptions. Conversely, late evening arrivals and tight connections in the late afternoon or night may be more vulnerable if the day’s delays accumulate.

Travel planners also recommend building in longer connection times at SFO during this period, particularly for passengers tying a domestic arrival to an international departure. Where possible, choosing itineraries with at least 90 minutes between flights, or even longer for cross border trips, can provide a buffer if arrival metering or holding patterns stretch out beyond the expected 30 minutes.

Finally, because airlines are still adjusting to the new arrival cap, schedules, aircraft types, and even routings may shift with relatively little notice over the next few weeks. Travelers are being advised to monitor their bookings closely in the days and hours before departure, keep airline apps and notifications active, and be prepared with alternative same day options in case a delay at SFO cascades into a missed connection.
