Collections: Human still decides · Embodied work
Executive brief
Automation is most defensible on routine optimization while humans retain authority over irregular operations and safety.
AI value · DFW taxi time
Company-reported20% shorter, about two minutes per flight and more than 11 taxi hours saved daily.
Company-reported before/after result; operating conditions may also vary.
Before
Manually evaluates arrivals and assigns among 136 DFW gates. → Taxis to the assigned gate and waits when conflicts occur.
After
Combines real-time flight and operational data to assign the nearest available gate with the shortest taxi time. → Supervises assignments and manages irregular operations and exceptions.
Human boundary
Operations teams may override assignments; pilots and air traffic control retain aircraft-movement authority.
Why it matters
Live flight, runway, and gate data can recommend the nearest gate; operations teams retain disruption control.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.

Exception path
Disruptions, unavailable gates, or safety constraints trigger planner reassignment and standard operations control.

Work that left the path
Human role before
Gate planners manually balanced hundreds of arrivals and conflicts.
Human role after
Planners supervise recommendations and focus on disruptions, constraints, and exceptions.
AI roleDecision mode: automated optimization of routine gate assignment; humans retain network and irregular-operation control.
Pre-Smart-Gating taxi performance.→20% shorter, about two minutes per flight and more than 11 taxi hours saved daily.
From 2021 test through November 2023. · American Airlines operations at DFW.
Company-reported before/after result; operating conditions may also vary.
Taxi operation without Smart Gating.→Estimated 1.4 million gallons of jet fuel and more than 13,000 metric tons CO2 avoided annually.
2023 system estimate. · Smart Gating operating across hubs.
Estimated, not independently audited, environmental benefit.
Anti-pattern
Treating estimated emissions savings as audited or allowing gate optimization to override safety control.
