Phillips 66 and United Airlines have signed an agreement under which Phillips 66 will supply sustainable aviation fuel (SAF) to United Airlines at Chicago O’Hare International Airport (ORD) and Los Angeles International Airport (LAX), helping advance lower-carbon fuels in Illinois and California.

Phillips 66 will supply United Airlines with 3 million gallons of SAF for use at ORD. This agreement includes the potential to increase the supply to 8 million gallons through the first half of 2025. Phillips 66 will deliver an initial 600,000 gallons of SAF to United Airlines at LAX by the end of 2024.

“We are excited to continue our collaboration with United Airlines to advance its lower-carbon goals and explore ways to benefit all segments of the aviation industry,” said Brian Mandell, Executive Vice President, Marketing and Commercial, Phillips 66. “Building on our legacy as a leading conventional jet fuel supplier, providing 10% of the fuel volumes nationwide, we are dedicated to offering additional fuel options to our customers.”

Phillips 66’s extensive commercial and logistical capabilities, including blending hubs in Illinois and on the West Coast, ensure efficient and reliable SAF distribution to customers. The Illinois Sustainable Aviation Fuel Purchase Credit further incentivizes the use of SAF, benefiting producers and encouraging investments in lower-carbon solutions.

SAF is a low-carbon-intensity fuel produced from renewable feedstocks. This supply of SAF is made from waste fats, oils and greases and can have up to 85% lower life-cycle GHG emissions than conventional jet fuel. SAF, once blended, is compatible with existing aircraft engines and airport fuel infrastructure, making it an essential component in the journey toward a lower-carbon future. With a rich history of aviation innovation — spanning breakthroughs like 100-octane avgas for military use in WWII and anti-icing additives for traditional fuels — Phillips 66 is now leading advancements in renewable fuels development.
