For these flights, SIA is using the fuel-efficient Airbus A350-900, which is powered by a combination of biofuel produced from used cooking oil and regular jet fuel. Flying for three months, these flights are servicing SIA’s Singapore to San Francisco direct route.
The first of the 12 flights departed from San Francisco on May 1 and arrived in Singapore on May 2, with 206 passengers on board.
SIA says these flights support the governmentâ€™s Sustainable Singapore Blueprint, which has the goal of improving the countryâ€™s air quality, among other targets. SIA believes these flights will also provide insights into the economics, logistical requirements, and performance of biofuels.
The aviation industry tested the use of biofuels from 2008 to 2011 before they were used by commercial airlines. Other companies that use biofuels include Lufthansa and United Airlines.
