Utilization of Aventus optimal wind data positions Southwest for the continued expansion of NextGen initiatives. Through optimization of the descent flight path, the service is estimated to save up to 84 000 tons of CO yearly in Southwest's operation. This is an integral part of the airlines initiative to reduce its environmental impact.
