American Airlines Jet Flies On Sustainable Aviation Fuel

American Airlines and Infinium announced the first use of electro sustainable aviation fuel (eSAF) on an American flight that departed Corpus Christi International Airport (CRP) and landed at Dallas Fort Worth International Airport (DFW), demonstrating the real-world deployment of next-generation, drop-in sustainable aviation fuel.

The airline said the flight marks a transition from innovation to implementation, signaling a new phase in scaling viable, low-carbon alternatives to conventional jet fuel and advancing the future of sustainable flight.

The eSAF used for the flight was part of a batch produced and blended at Infinium’s Pathfinder facility in Corpus Christi, Texas — the world’s first commercial-scale power-to-liquids eFuels production site, which has been operating since 2023. The eSAF batch was blended with conventional jet fuel and tested to meet the ASTM International specification for Jet A, certifying its use in today’s aircraft engines and fueling infrastructure without further modification.

It was then delivered to the common jet fuel tanks at CRP before being allocated to American’s flight to DFW — the first delivery of SAF made without biobased feedstocks to a commercial airport in the U.S. The flight demonstrates the compatibility of eSAF with existing aviation jet fuel supply chains.

Infinium’s eSAF is made using waste CO₂ and renewable electricity, delivering a meaningful reduction in lifecycle greenhouse gas (GHG) emissions compared to conventional jet fuel. Infinium’s eSAF can reduce lifecycle GHG emissions by over 90% compared to conventional petroleum-based jet fuel.

"This flight represents a significant moment for aviation," said American’s CEO Robert Isom. "Through our partnership with Infinium, we're demonstrating how next-generation technologies like eSAF can move from early investment to real-world application. Scaling SAF production at lower prices is essential to reducing emissions, strengthening our long-term competitiveness, and continuing to deliver the connectivity and economic benefits that our customers rely on."
