Hong Kong-based Cathay Pacific has become the first commercial airline in the Asia-Pacific region to partner with Google on advancing research on contrail avoidance and will be the first airline globally to test contrail avoidance on ultra-long-haul-flights. Using Google\u2019s AI-powered contrail mitigation technology, the companies have started trials to evaluate the operational feasibility and constraints of contrail avoidance across Cathay\u2019s network. An operational trial began in late 2025 with more than 100 flights targeted. Over 80 of these flights were selected to follow contrail avoidance routes and Google estimates they achieved roughly a 40% reduction in the warming impact of contrails. The Hong Kong-Singapore corridor, where persistent contrails frequently form, was one of the routes tested.<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

The partners report<\/a> early analysis indicates that minor altitude adjustments can successfully prevent contrails, with actions taken on this single route accounting for more than 50% of the trial\u2019s total climate impact.<\/p>\n\n\n\n

Using real-world operational data from the flight trials, they expect the insights will help build further understanding of the impact and possible actions airlines across the industry can take to implement and manage contrail avoidance.<\/p>\n\n\n\n

\u201cAviation needs solutions to address climate change and AI is accelerating that progress. This partnership combines Cathay\u2019s operational expertise with Google\u2019s world-class AI capabilities to tackle complex sustainability challenges at scale,\u201d said the airline\u2019s Lawrence Fong, Director Digital and IT.<\/p>\n\n\n\n

Google\u2019s contrail mitigation solution combines AI-based predictive models, satellite imagery detection tools and weather intelligence to forecast contrail-forming zones. This data allows flight dispatchers and pilots to make informed altitude adjustments navigating around these zones in the same routine way used to avoid turbulence, explains the company.<\/p>\n\n\n\n

Cathay Pacific combines in-flight wi-fi connectivity with its in-house developed Electronic Flight Folder. The EFF system equips pilots with dynamic Google contrail forecasts alongside real-time operational parameters, enabling decision-making in the cockpit without disrupting normal operations.<\/p>\n\n\n\n

While the initial trial delivered \u201cencouraging\u201d results on individual flights, the partners say further trials and research are needed to assess the benefits of applying contrail avoidance measures across airlines and airspaces. \u201cThe availability of such robust science evidence will enable further industry considerations and policy development by airlines, regulators and other industry players,\u201d they add.<\/p>\n\n\n\n

The partners are therefore embarking on a larger second phase of flight trials to generate a broader set of real-world operational data and further insights across Cathay\u2019s Asia and transpacific network. Contrails.org, a nonprofit initiative dedicated to advancing the science of contrail mitigation, has also joined the project.<\/p>\n\n\n\n

\u201cAt Google, we believe AI has the power to help address complex environmental challenges and our partnership with Cathay Pacific is a prime example of this in action \u2013 researching how predictive AI can be deployed in live operations to help address the climate impact of contrails with today\u2019s aircraft and today\u2019s fuel,\u201d commented Michael Yue, Managing Director and General Manager, Google Hong Kong. \u201cThis work reflects our ongoing commitment to developing sustainable solutions that deliver lasting impact, and we\u2019re excited to expand our trial with Cathay Pacific and continue contributing to open climate science together.\u201d<\/p>\n\n\n\n
