The Federal Aviation Administration will begin rolling out a new predictive flight-management system this month after Administrator Bryan Bedford met Thursday with the chief executives of the largest U.S. passenger airlines to coordinate its introduction, according to Reuters. The system, called Strategic Management of Airspace, Routes, and Trajectories, is intended to identify congestion before aircraft leave their gates and help carriers and air-traffic managers agree on better departure times and routes.

The September 10 meeting moved the program from a procurement announced in June toward an operational test with consequences for passengers. American, United, Delta, Southwest and other carriers joined the discussion as the agency prepared initial deployment. The FAA has said the software could eventually reduce delays, improve traffic flow and increase usable capacity, but the first phase will focus more narrowly on recovering schedules after weather cancellations.

That distinction matters. SMART is an $875 million, 12-year technology contract, not evidence that delays have already fallen. Its value will depend on the accuracy of its forecasts, the quality of the data supplied by airlines and the FAA, and whether carriers accept recommendations that may benefit the network while inconveniencing an individual flight. The current news is that deployment is beginning and the industry is aligning around it; measurable passenger benefits remain to be demonstrated.

A shared plan before departure

Air traffic is now managed through a mix of forecasts, flight plans and real-time interventions. When thunderstorms close routes or an airport loses arrival capacity, managers commonly meter departures, hold aircraft on the ground or reroute flights already in the air. Those measures protect safety, but they can propagate through a tightly scheduled network as crews, gates and aircraft arrive late for their next assignments.

SMART is designed to move more of that coordination earlier. An FAA brief says the cloud-based platform will combine airline schedules, weather, airport capacity, airspace conditions and operating constraints in a shared view. Artificial intelligence will continuously update traffic forecasts and planning recommendations, allowing the agency and carriers to address conflicts while there is still time to adjust routes or departure slots.

The software will sit alongside existing systems rather than replace the controller’s safety function. The FAA says controllers will remain responsible for separating aircraft. In practical terms, SMART is a planning layer: it attempts to calculate where demand will exceed capacity and give operators earlier options, while certified operational systems and human controllers continue to make and execute safety-critical decisions.

Why airline schedules amplify disruption

The case for earlier planning is rooted in the scale and interdependence of commercial aviation. U.S. airlines operate more than 28,000 flights and carry about 2.7 million passengers on a typical day, according to industry data. A capacity reduction at a major hub can therefore affect travelers who never pass through the original weather system, because their aircraft or crew may have been scheduled to arrive from the disrupted airport.

The FAA’s own description of the existing process says weather data, airport capacity and other information can reside in separate systems, requiring traffic managers to consult multiple screens and spreadsheets. Conflicts may not become apparent until flights are at the gate, taxiing or airborne. At that stage, the set of workable responses narrows: a gate may already be occupied, a crew may approach its duty-time limit, or an aircraft may carry insufficient fuel for an extended reroute.

Thursday offered an ordinary example of the conditions the new system is meant to anticipate. The FAA’s daily report warned that thunderstorms could slow traffic around Washington, Philadelphia, Louisville and several Florida airports, while wind threatened delays in New York. SMART cannot remove storms or create runways, but a reliable common forecast could help airlines thin or move departures before congestion cascades.

A new layer on an aging network

The new platform arrives within a much larger air-traffic-control overhaul. Congress provided $12.5 billion for updated technology and understaffed facilities, and the FAA is seeking another $10 billion, earlier reporting found. SMART and the related Flow Management Data and Services platform are supposed to modernize how the national command center balances demand with capacity, while separate projects address radars, radios, telecommunications and controller staffing.

The need is substantial. A GAO review of 138 FAA air-traffic-control systems found 51 were unsustainable and another 54 potentially unsustainable. Fifty-eight of those 105 systems had critical effects on safety or efficiency. The watchdog also found that some modernization projects would not finish for a decade or more, and that the agency lacked modernization investments for four of the most concerning systems.

SMART does not by itself remedy that backlog. A sophisticated forecasting tool still depends on reliable communications, surveillance, weather and flight-plan data. If an upstream system fails or supplies stale information, better analytics cannot manufacture a dependable operating picture. That is why the software contract should be viewed as one part of modernization rather than a substitute for physical infrastructure, staffing and disciplined maintenance.

What travelers could notice

If the system works as intended, the first passenger benefit may be faster recovery rather than a dramatic reduction in routine delays. After cancellations, airlines must rebuild a network whose aircraft and crews are no longer where the timetable expected them to be. Reuters reported that the initial application will help reschedule flights canceled by bad weather, with broader predeparture coordination of schedules and trajectories contemplated later.

Earlier decisions could also make disruptions less opaque. A shared estimate of available capacity may allow airlines to cancel or retime flights sooner, giving passengers more time to rebook and reducing long waits after boarding. The trade-off is that optimization may move inconvenience forward: a traveler could receive an earlier delay or cancellation even when conditions at the departure airport appear normal because the system is protecting scarce capacity elsewhere.

The economics create a strong incentive. In 2024, direct aircraft operating costs averaged $100.76 for every minute of block time, according to an A4A analysis based on federal filings. The same analysis cited a pre-pandemic estimate of $33 billion in annual delay costs across airlines, passengers, lost demand and wider economic effects. Those figures do not forecast SMART’s savings, but they show why even modest improvements in system recovery could matter.

The hard questions begin with allocation

Predicting a conflict is easier than deciding who should absorb it. Airlines raised private concerns earlier this year about how the FAA would determine which flights must move and whether the fall timetable was feasible. A choice that minimizes total delay could still disadvantage a smaller carrier, a regional route, a late-booked flight or passengers with limited alternatives. The agency has not yet published performance results showing how recommendations will be allocated in those cases.

There are also governance questions around automation. The FAA says SMART uses AI, but its public materials emphasize operational inputs and recommended plans rather than autonomous control. Before the system can earn broad trust, the agency and airlines will need auditable measures for forecast accuracy, canceled-flight recovery, on-time performance, fuel use and distributional effects across carriers and airports. They will also need procedures for overrides when local knowledge conflicts with a model’s recommendation.

Past modernization offers both a foundation and a warning. The FAA says its Next Generation Air Transportation System produced $10.9 billion in benefits from 2010 through 2023 across more than 200 implementations, and its NextGen account describes existing tools that sequence traffic, exchange data and route aircraft more efficiently. Yet the GAO’s findings on slow baselining and incomplete oversight show that a technically promising program can still lose time or value during acquisition and deployment.

Evidence must follow the rollout

Airlines for America and United Chief Executive Scott Kirby have endorsed SMART’s potential, and their operational cooperation will be essential. But the trade group represents carriers that also stand to save money, while the contractor and FAA are responsible for the program’s success. Their support is relevant evidence of industry alignment, not independent proof of results.

The most useful early disclosures would compare SMART-assisted recovery events with similar disruptions handled under existing procedures. Measures should include passenger arrival delay, cancellations, misconnections, aircraft and crew recovery time, and the frequency with which controllers or airline dispatchers reject recommendations. Safety indicators must remain separate from efficiency gains so that faster traffic flow is never treated as evidence of safer operations.

The September rollout begins a consequential test of whether a shared predictive view can make a complex national network more resilient. The FAA has established the mechanism, funding and industry participation needed to try. What it has not yet established is the size, consistency or fairness of the benefit. For travelers, the decisive evidence will be fewer cascading disruptions and quicker recovery when weather constricts the system, measured across airports and carriers rather than asserted in advance.
