DOT Rolls Out AI-Powered SMART System to Cut Flight Delays

The U.S. Department of Transportation and the Federal Aviation Administration have begun a limited debut of a new AI-supported air-traffic planning platform called SMART, positioning it as an early step toward preventing delays and cancellations before they ripple across airline schedules.

What SMART is and where it’s launching first

Publicly available information shows SMART is short for Strategic Management of Airspace, Routes and Trajectories, and it is designed to help the FAA and industry partners anticipate bottlenecks rather than reacting after congestion builds. The system’s debut is limited at the outset, with operations starting in the airspace around Washington, D.C.

Published coverage indicates the initial deployment is tied to the busy airspace that includes Ronald Reagan Washington National Airport, Washington Dulles International Airport, and Baltimore-Washington International Marshall Airport. The FAA has described this as a “limited mode” rollout, with a plan to gradually expand to other parts of the country.

SMART is being framed as an airspace management and scheduling aid, not an autopilot or a replacement for controllers. DOT and FAA materials emphasize that recommendations are reviewed by FAA staff, and local facility leadership can choose whether to accept or decline scheduling suggestions.

How the AI tool is supposed to reduce delays and cancellations

According to program descriptions released by the FAA, SMART’s AI-supported engine synthesizes large volumes of operational data to produce a more comprehensive picture of where aircraft are going, how much demand the system can handle, and where congestion or weather could create problems. The underlying idea is to spot conflicts early enough that small schedule or routing adjustments can avert larger disruptions later in the day.

The inputs described across official material and published reporting include airline schedules, weather, airport capacity, airspace conditions, and operational constraints. Additional public descriptions point to integrating multiple streams of data into a single planning environment, which can be especially relevant in regions where runway capacity, storms, and traffic density collide.

For travelers, the promise is less time spent in ground-delay programs, fewer last-minute reroutes that cascade into missed connections, and potentially fewer cancellations tied to the network getting overwhelmed. The practical effect, if the model performs as intended, would likely show up first in smoother peak-period operations and faster recovery after weather events in the Northeast corridor.

SMART’s place in a wider FAA modernization push

SMART is not being presented as a standalone fix. It sits within a broader technology and infrastructure modernization effort that the FAA has tied to replacing aging components across the National Airspace System, including communications, surveillance, automation, and facility systems.

FAA planning documents and fact sheets describe a goal of implementing a “brand-new” air traffic control system by the end of 2028, with the modernization spanning items such as new network connections, radios, digital voice switches, replacement radars, and expanded surface surveillance and airport data tools. The same materials point to equipment-related delay minutes rising sharply in 2025 versus earlier historical averages, which has been used as part of the rationale for accelerated upgrades.

Within that modernization lane, the FAA has described a related backbone effort known as Flow Management Data and Services (FMDS), with SMART described as an enhancement within FMDS focused on preventing congestion and delays by coordinating schedules and trajectories before aircraft depart. Separately, published coverage has linked the SMART work to a 12-year contract valued at $875 million with Air Space Intelligence to provide the SMART tool and FMDS capabilities.

Reliability questions, guardrails, and what travelers should watch next

The rollout arrives during a period of heightened public attention on air traffic system reliability, particularly after well-publicized technical disruptions affecting major airports. Recent reporting on outages in the Northeast has highlighted how equipment failures can trigger widespread delays, while also noting that the AI-enabled tool being tested around Washington, D.C., did not appear connected to those incidents.

At the same time, published coverage reflects ongoing debate about transparency and performance claims for AI systems used in high-stakes environments. The FAA’s public positioning emphasizes guardrails: SMART is advisory, not controlling; it does not take over aircraft; and it does not remove the human decision-making chain in air traffic planning.

For passengers, the most meaningful near-term signals will be operational and measurable rather than promotional. As SMART expands beyond the Washington region, travelers can monitor whether the FAA publishes clear benchmarks such as fewer delay minutes during forecast storms, faster post-weather recovery, fewer extended ground holds, and more predictable arrival flows at constrained airports.
