American Airlines Reduces Contrails Using AI Forecasts

American Airlines and Google said Thursday they reduced the climate impact of a January–May 2025 transatlantic trial by using an AI-based contrail forecasting tool in flight planning. The study covered 2,400 U.S.–Europe flights (half offered avoidance options) and found that of the 112 flights that took avoidance options, contrails fell 62% and estimated warming from those flights fell about 69%.
Scoring Rationale
High novelty and industry relevance from official trial, limited by small subset of flights and need for broader trials.
