United Airlines plans to purchase as much as 1 million gallons of sustainable aviation fuel (SAF) for use at its Chicago hub, O’Hare Airport (ORD). Produced by Finland-based Neste, the biofuel will reach ORD by the end of August and promises a greener future for commercial flight. Here’s what you need to know.

Sustainable aviation fuel is an emerging technology that offers similar performance yet lower emissions when compared to petroleum-based fuels. United’s addition of SAF to its O’Hare hub follows its use at other locations, including Los Angeles International Airport, London’s Heathrow Airport, San Francisco International Airport, and Amsterdam Airport Schiphol. United Airlines continues to be bullish on the fuel’s future.

According to the U.S. Department of Energy, “SAF is a biofuel used to power aircraft that has similar properties to conventional jet fuel but with a smaller carbon footprint. Depending on the feedstock and technologies used to produce it, SAF can reduce life cycle GHG emissions dramatically compared to conventional jet fuel.” With air travel a significant emissions source, SAF could play a significant role in reducing carbon.

United President Brett Hart said, “While the market for SAF is still in its infancy, there is a huge opportunity today for airlines and policymakers to work together to support its continued growth.” He continued, “SAF at O’Hare was made possible thanks to … the Illinois legislature passing [SAF] tax incentives.”

Beyond that, the United Airlines Ventures Sustainable Flight Fund has invested more than $200 million toward research, technology, and production of SAF. Still, SAF makes up only 0.1% of the carrier’s fuel consumption.

Neste Vice President for Renewable Aviation Business, Alexander Kueper, commented: “We are excited to expand our partnership with United and see our SAF being used at one of the major airports in the U.S. It underlines our commitment to supporting the U.S. aviation industry in its efforts to decarbonize.”

The pets on the emergency flight were previously in the care of rescues and shelters in the Los Angeles County area.

This Asian airline was just named best in the world

Korean Air named best airline in the world

Korean Air Boeing 787-9

Korean Air earned the “Airline of the Year 2025” title in AirlineRatings.com annual round-up. The outlet, based in Australia, pointed to the Asian airline’s focus on “passenger comfort” which included roomy economy seating. That results from the carrier retaining its original seating configuration and not adding a 10th row.

AirlineRatings.com CEO Sharon Petersen said: “While many airlines have added a 10th seat per row on 777 aircraft and reduced seat pitch in economy to 31 to 32 inches (down from the previous 32 to 33 inches), Korean Air has chosen not to follow this trend.” She added: “These awards are not a popularity contest or a people’s choice award. As airline experts, we conduct a meticulous assessment of each category to help travelers identify the best airlines for quality, value, and safety.” The award follows Korean Air’s recent merger with Asiana Airlines, which was the most significant in the history of Asian aviation.
