United is using 100% sustainable fuel

United is the first to fly aircraft full of passengers using 100% sustainable fuel.

The commercial carrier announced, that they flew an aircraft full of passengers using 100% sustainable aviation fuel (SAF). This will serve as a turning point in the industry´s effort to combat climate change. The demonstration flight departed Chicago O´Hare and landed in Washington, D.C. with more than 100 passengers on board. United reported, that they used 500 gallons of SAF in one engine and the same amount of conventional jet fuel in the other engine to further prove there are no operational differences between the two and to set the stage for more scalable uses of SAF by all airlines in the future. Currently it is only permitted to use a maximum of 50% SAF on board.
