About this project
The description is as the source gives it.
Cathay Pacific partnered with Google to trial AI-powered contrail mitigation technology on its network, including ultra-long-haul flights. The operational trial began in late 2025 with over 100 flights targeted, achieving roughly 40% reduction in contrail warming impact on tested routes. Evidence: "Cathay Pacific and Google today announced a partnership to advance research on contrails... An operational trial began in late 2025, with more than 100 flights targeted across Cathay Pacific's network. Over 80 flights followed contrail-avoidance routes, and Google estimates that these flights achieved roughly 40% reduction in the warming impact of contrails." — https://news.cathaypacific.com/translation-cathay-pacific-and-google-partner-to-research-and-trial-ai-powered-contrail-avoidance
