JetBlue Airways, along with DHL and Scandinavian Airlines (SAS), has announced its participation in a pilot 'book and claim' system for purchasing 20,000 tonnes of Sustainable Aviation Fuel (SAF). This new scheme, developed by SAF market accelerator Future Energy Global (FEG), allows airlines to invest in and receive the environmental benefits of SAF without the fuel being physically available at their specific locations, thereby reducing costs and emissions associated with transportation. The system is designed to accelerate the production and adoption of SAF by providing a clear demand signal to producers. While this is a significant step in the company's sustainability efforts, there is no immediate information available on the market's reaction to this announcement. Separately, on the same day, JetBlue, along with Delta Air Lines and Latam Airlines, canceled 17 flights across the US and South America, affecting routes from hubs like Boston.
