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.

This is one giant leap for aviation (and for mankind… no pun intended). SAF is one of the fastest and most effective ways we’ll meet our goal of being 100% green, carbon neutral, without relying on carbon offsets.
