France, March 19 -- Airline Amelia and Thales announced the successful large-scale deployment of their contrail-avoidance solution. This initiative, launched in 2024 on Amelia flights between Paris and Valladolid (Spain), optimizes flight plans by modifying aircraft altitude rather than lateral trajectory in order to avoid the formation of condensation trails (contrails). This reduces the climate impact of each flight while limiting additional fuel consumption.In 2025, Amelia deployed this solution across all eligible flights, including Airbus A319/320 and Embraer ERJ-145 aircraft. According to the climate-impact estimation models used, this avoided more than 2,000 tonnes of CO equivalent (CO2e) during 2025 and reduced the average climate i...
