Delta, Shell expand SAF partnership at US hubs in five-year agreement

Delta Air Lines has signed a five-year agreement with Shell Aviation to expand sustainable aviation fuel supply across multiple US airports through 2030, building infrastructure to support consistent SAF delivery as the carrier advances decarbonization efforts, the airline said in a July 15 statement.

The partnership will expand SAF availability at key Delta hubs and priority cities, including Los Angeles, New York's JFK, Boston, Minneapolis-St. Paul and Portland, with Shell supporting the blending, logistics and distribution infrastructure needed to integrate SAF into day-to-day operations.

The agreement builds on existing SAF initiatives between the companies and decades of collaboration on conventional jet fuel supply.

The deal underscores the aviation industry's push to scale SAF adoption amid constraints from limited production and high costs. Airlines increasingly view long-term supply agreements and infrastructure investments as critical to securing reliable SAF availability while advancing industrywide decarbonization goals, with sustainable fuel seen as the most immediate pathway to lowering aviation emissions.

Infrastructure focus

Shell will support both blended and neat SAF deliveries at select hubs and priority cities, establishing the logistics, blending and distribution capabilities required for dependable supply across Delta's network. The infrastructure-first approach aims to ensure SAF can scale with demand while maintaining operational reliability.

"Current instability and uncertainty have made one thing very clear to consumers and businesses alike -- supply diversity matters," Amelia DeLuca, Delta's chief sustainability officer, said. "With Shell, we're proving that scaling SAF isn't theoretical, it's achievable. This is about activating real supply chains at scale and creating a model that others can build on as we work across the industry to expand lower-impact travel."

The collaboration will also explore next-generation fuel technologies, including alcohol-to-jet and power-to-liquid pathways, to unlock additional supply and further reduce life cycle emissions over time.

"This collaboration delivers on today's fuel needs and tomorrow's aviation solutions," Reema Bari, head of aviation Americas at Shell, said. "By supplying conventional jet, SAF and longer-term innovation, the deal will help strengthen energy security and contribute to the transformation of aviation."

Building on momentum

The agreement builds on Delta's broader SAF momentum, including its role as an anchor partner in the Minnesota SAF Hub coalition, which aims to scale SAF production and replace conventional jet fuel.

In 2024, two shipments of 7,000-plus gallons of SAF arrived at the Minneapolis-St. Paul International Airport and the Detroit Metropolitan Airport, marking the first time in Minnesota and Michigan aviation history that SAF was delivered to those airports.

Delta achieved a key milestone in September 2025 by taking delivery of more than 400,000 gallons of SAF at Portland International Airport in partnership with Shell, marking the first commercial-scale uplift of SAF at the airport.

The neat SAF was shipped to Portland's Zenith Terminal, blended with traditional jet fuel to meet regulatory requirements, then delivered to the airport via barge, truck and pipeline before entering the fuel system.

Delta and Shell previously said a two-year agreement in April 2023 for Shell to supply up to 10 million gallons of neat SAF to Delta's Los Angeles hub, increasing the airline's SAF commitments to over 200 million gallons.

That agreement also included testing Avelia, a blockchain-powered digital SAF solution launched by Shell and partners, to track SAF delivery and use data with full transparency while avoiding issues such as double-counting.

Delta aims to achieve net-zero emissions by 2050, with the company noting that roughly 90% of its carbon emissions come from jet fuel, making SAF a key element of its decarbonization efforts.

The carrier targets SAF comprising 10% of its fuel use annually by the end of 2030 and 35% by 2035, subject to third-party investment and timely facility development.

The life cycle carbon emissions of producing neat SAF can be up to 80% lower than those of traditional jet fuel, according to Delta.

Platts, part of S&P Global Energy, assessed SAF California at 1,042.15 cents/gallon and assessed SAF California, withcredits detached, at 539.10 cents/gal on July 14. Platts assessed ATF 30/70 prices in California at 528.68 cents/gal. Platts assessed SAF Illinois at 1,144.45 cents/gal and assessed SAF Illinois, with credits detached, at 546.35 cents/gal, based on an indicative premium of neat SAF to jet kerosene Chicago Pipeline of 201.42 cents/gal.
