Flying in the future might be possible using cooking oil for fuel as it turns out it could power the world’s largest passenger airliner.

Airbus performed the first-ever A380 flight powered by 100 percent Sustainable Aviation Fuel (SAF) derived mainly from cooking oil and other waste fats.
 SAF can be made from renewable sources such as used cooking oil, municipal waste and woody biomass. It is a fuel that has the potential to reduce lifecycle emissions by up to 80%, compared with conventional aviation fuel.

All Airbus aircraft are already certified to fly using up to 50 percent SAF mixed with kerosene, but the company aims to take things a step further by earning 100 percent SAF flight certification before 2030.
