Southwest Airlines Sells Its Clean Jet Fuel Business

Southwest Airlines has sold its renewable energy business to Conestoga, the carrier confirmed to Skift Thursday, a deal that covers Saffire Renewables, a Southwest subsidiary acquired in 2024.

It includes its intellectual property, certain technologies, a planned pilot sustainable aviation fuel (SAF) production facility, and key leadership team members.

Saffire started as a startup making renewable ethanol from corn stover, the leftovers of corn plants after harvest, which can then be turned into jet fuel.
