The U.S. Department of Transportation has begun rolling out a new AI-enhanced air traffic “smart system” intended to predict congestion before it forms and reduce the kind of cascading delays that have frustrated airline passengers across the country in recent years.

DOT rolls out SMART AI air traffic system to cut delays

AI-backed SMART platform begins phased deployment

According to published coverage, the Department of Transportation launched the system on Monday, September 21, 2026, as a support tool for the Federal Aviation Administration’s air traffic managers rather than a direct replacement for human controllers. The Strategic Management of Airspace, Routes and Trajectories platform, known by the acronym SMART, is initially being introduced in the busy airspace around Washington, D.C., one of the country’s most delay-prone corridors.

Reports indicate that SMART continuously ingests data on airline schedules, airport capacity, airspace constraints and real-time weather, looking for patterns that typically lead to ground stops, reroutes or cancellations. Instead of waiting for congestion to build, the system is designed to highlight potential bottlenecks hours in advance so planners can adjust routes, tweak departure times or meter arrivals before passengers start feeling the impact.

The FAA awarded an $875 million, 12-year contract earlier in 2026 to California-based Air Space Intelligence to provide the SMART platform as part of a broader modernization push. Public documents describe SMART as a kind of “digital brain” for traffic flow management, augmenting existing tools in the agency’s Air Traffic Control System Command Center with predictive analytics drawn from commercial airline operations and previous disruptions.

DOT materials frame SMART as an early deliverable within a larger plan to overhaul aging air traffic infrastructure by the end of the decade. The system is being layered onto the current network rather than switched on nationwide all at once, with officials emphasizing a gradual rollout to allow for tuning, performance checks and feedback from controllers and airlines.

Part of a multibillion-dollar upgrade of aging infrastructure

SMART sits inside a much larger effort to replace technology that the Government Accountability Office and other federal reviewers have repeatedly labeled as unsustainable. A 2024 risk assessment of 138 core air traffic systems found that more than a third were already considered unsustainable and nearly 40 percent potentially unsustainable, highlighting how often the FAA has been forced to slow traffic when equipment breaks instead of relying on modern, redundant networks.

Recent fact sheets from the FAA and Department of Transportation point to a “brand new air traffic control system” program targeting the end of 2028 for a wide-scale refresh of radar, communications, automation software and related hardware. Within that plan, SMART is positioned as a key automation layer that can make better use of the new infrastructure once it is in place, particularly during peak travel periods and disruptive weather patterns.

Budget documents for the mid-2020s reference a federal commitment of roughly $12.5 billion toward air traffic modernization, including smart routing tools, higher-speed data links, advanced surface surveillance at major airports and improved weather sensing in remote regions such as Alaska. Those investments are intended to cut equipment-driven delay minutes, which federal data show were roughly three times higher in 2025 than the average from 2010 through 2024.

For travelers, the most visible pieces of this program so far have been airport construction projects and incremental changes like new surface movement displays and electronic flight strips in control towers. SMART represents a less tangible but potentially more impactful change, altering how traffic managers across the system coordinate flows long before passengers arrive at the airport.

How SMART is expected to reduce delays for travelers

The new platform’s core promise lies in how it uses data that, until now, has often been handled in separate silos. Public descriptions of SMART’s capabilities emphasize that it can rapidly simulate how storms, shifting winds, runway closures or military airspace restrictions might affect routes, then rank possible responses and highlight options that keep more of the schedule intact.

In practice, that could mean suggesting earlier reroutes around a developing thunderstorm line, recommending temporary use of alternate arrival streams at a constrained hub, or identifying when a modest slowdown at one airport might prevent large-scale gridlock across a region. By anticipating those scenarios, the system is intended to help airlines and controllers avoid the last-minute ground stops and rolling delays that have often turned isolated disruptions into day-long snarls.

Reports in outlets such as The Wall Street Journal and The Center Square note that SMART is designed to work hand in hand with airlines’ own operations centers. Because it draws on published schedules and up-to-date flight plans, as well as airport and airspace capacity models, the tool can suggest ways to rebalance routes and departure times that may be less disruptive than the broad traffic management initiatives traditionally used in bad weather.

For passengers, visible changes will likely arrive slowly. On-time performance statistics for the busiest travel weekends and severe weather days will be among the main indicators of whether SMART is delivering meaningful benefits. DOT performance plans already track systemwide on-time arrival rates and minutes of delay by cause, metrics that can show whether predictive tools are actually shrinking the impact of storms, equipment issues or congestion.

Initial rollout in Washington region with plans to expand

The current deployment focuses on the Washington, D.C. area, an airspace region that connects some of the country’s most heavily used routes along the East Coast. Publicly available information indicates that this corridor was chosen because of its complex mix of long-haul, regional and government-related flights, as well as its history of congestion during holiday peaks and summer thunderstorms.

As SMART’s performance is evaluated, aviation analysts expect the FAA to extend the system to additional facilities and airspace regions, gradually increasing its influence on national traffic flows. Financial and planning documents describe a multi-year path in which new automation tools and communications upgrades are introduced in stages, with the goal of having a far more integrated, data-rich traffic management environment by the late 2020s.

Travelers may first notice the effects on days that have historically been problematic, such as holiday weekends or when major storm systems sweep across multiple hubs. If SMART works as intended, airlines and the FAA should be able to maintain higher throughput and avoid the sharp spikes in cancellations and multi-hour delays that have characterized many of the worst disruption days since the pandemic.

However, performance will depend on more than software. Federal oversight reports stress that controller staffing, airport infrastructure and airline scheduling practices all interact with traffic management tools. SMART is being introduced against a backdrop of continued hiring and training efforts for new controllers, as well as ongoing construction at major hubs designed to add gates, expand taxiways and improve deicing operations.

What this means for airline passengers in the coming years

In the near term, travelers are unlikely to see an overnight transformation at the gate display. Flight status boards will still show delays during severe storms, and structural challenges like limited runway capacity at some big-city airports cannot be solved by software alone. But if delay statistics begin to improve starting with the 2027 summer season, it will be an early sign that the new system is helping air traffic managers get ahead of trouble.

Passengers planning trips through Washington, D.C. and, later, other major hubs may benefit most during complex weather patterns, when traditional tools have struggled to keep up. More targeted reroutes and earlier, more accurate schedule adjustments could translate into fewer surprise cancellations, shorter holding patterns and better chances of making tight connections when storms move through.

For now, SMART’s debut underscores how central artificial intelligence and predictive analytics have become to transportation planning. As the broader brand new air traffic control system program progresses toward its 2028 target, the success or shortcomings of this “smart system” will likely shape how aggressively federal agencies lean on similar technologies in other parts of the national transportation network.
