For most flights, the industry is beginning to turn to new fuels. In September, JetBlue made its first flight using a renewable blend fuel. Though chemically identical to regular jet fuel, 15.5% of it came from used cooking oil from restaurants, which otherwise would have been wasted. Next year, the airline will begin buying around 33 million gallons of biofuel a year, or about 20% of the fuel it uses annually at JFK.
