American Airlines (NASDAQ: AAL) and Infinium announced the first delivery of electro sustainable aviation fuel (eSAF) to a commercial airport for use in a passenger flight, according to a press release issued Aug. 6, 2026.

The flight departed Corpus Christi International Airport (CRP) and landed at Dallas Fort Worth International Airport (DFW). The eSAF was produced at Infinium's Pathfinder facility in Corpus Christi, Texas, which the company describes as the first commercial-scale power-to-liquids eFuels production site, operating since 2023. The fuel was blended with conventional jet fuel and tested to meet ASTM International specifications for JetA.

Infinium states the delivery marks the first time SAF produced without biobased feedstocks was delivered to a commercial airport in the U.S. The company claims its eSAF, made from waste CO₂ and renewable electricity, can reduce lifecycle greenhouse gas emissions by over 90% compared to conventional petroleum-based jet fuel.

American Airlines holds an offtake agreement for commercial volumes of eSAF from Infinium's Project Roadrunner, a separate facility currently under construction. Project Roadrunner is financed by Breakthrough Energy Catalyst and Brookfield Asset Management, with nonrecourse project debt from HSBC. The facility is expected to begin eSAF production and deliveries in 2027, with a projected capacity of over 5 million gallons annually. A separate agreement with Citi supports Scope 3 emissions reductions from employee travel.

American Airlines CEO Robert Isom said the flight demonstrates how eSAF "can move from early investment to real-world application," adding that scaling SAF production at lower prices is essential to reducing emissions and long-term competitiveness.

Infinium CEO Robert Schuetzle noted the company has been producing eDiesel and eNaphtha at its Pathfinder facility since 2023 and described the addition of eSAF as "another meaningful step forward in bringing practical, low-carbon fuel solutions to industry."

Sustainable aviation fuel currently accounts for less than 1% of total jet fuel use worldwide, according to figures cited in the release. Global aviation consumes nearly 100 billion gallons of jet fuel annually.
