Singapore Airlines biofuel flights between the island city-state and San Francisco have just been announced. There will be 12 nonstop flights total over three months, or one per week. The Airbus A350-900s making the trips will be powered by a blend of biofuel derived from cooking oil and regular jet fuel. Singapore Airlines' goal in running these green flights is two-fold. First, it wants to encourage the use of biofuels at home. Second, the company wants to gather data to share with industry stakeholders.
Airlines will do anything to make more money, and usually that means cutting features and adding costs. However, if the Singapore Airlines biofuel flights prove to be more efficient (as in cheaper) than nonstop flights powered solely by conventional jet fuel it could raise eyebrows and encourage more airlines to green gas tanks. There's currently no word on whether the Singapore Airlines biofuel nonstop flights will continue after the three-month period ends.
