United Airlines burned through 83,000 metric tons of sustainable aviation fuel in 2025, a 104% jump from the year before, and Neste just locked in the supply to keep that number climbing.
Neste and United extended their SAF agreement covering Chicago O'Hare International Airport and Amsterdam Airport Schiphol, with deliveries running Amsterdam June through August 2026 and Chicago July 2026 through June 2027.
"United was the first airline in the world to fly on blended SAF in regular operations, and we've spent the years since proving it can work at scale in day-to-day flying – including being the first airline to purchase and use blended SAF at Chicago O'Hare. Continuing our work with Neste across two continents reflects a shared conviction that SAF is available and capable of being scalable." - Lauren Riley, United Airlines
United became the largest SAF user among major US airlines in 2025.
The airline has used Neste MY SAF at Amsterdam since 2022, and it became the first carrier to use blended SAF at Chicago O'Hare in August 2024.
SAF deployment now reaches six of United's seven domestic hubs after Newark, Washington DC, and Houston joined the program in 2025.
"This extended agreement with United Airlines covering two international airports across two major aviation regions is a testament to our joint belief in the critical role of SAF in reducing aviation related GHG emissions." - Carl Nyberg, Neste
For frequent flyers tracking airline sustainability claims, this extension gives United a locked supply chain stretching into 2027 rather than a one-off pilot program.
United set a net-zero emissions target for 2050, and the Neste extension gives it fuel visibility on two continents for the next two years.
The next checkpoint arrives when Chicago deliveries wrap in June 2027, and whether United's SAF volume keeps doubling will show if this scales beyond flagship hubs.
