United Airlines Operates First Flight Powered by 100% Sustainable Aviation Fuel

Nov 1, 2021 12:10 PM ET

United was the first airline in the world to operate a flight powered by 100% drop-in sustainable aviation fuel (SAF).

One engine was powered with 100% SAF and the other had traditional jet fuel. This particular SAF can provide an estimated 75% reduction in lifecycle CO2 emissions, bringing us one step closer to making 100% green — carbon-neutral-aviation — the norm.
