Following up on an announcement made in September about the establishment of permanent supplies of sustainable aviation fuel (SAF) at two of its FBOs, Signature Flight Support said the fuel is now available at its facilities at San Francisco International Airport (SFO) and at London Luton Airport in the UK.

“We’re filling aircraft right now—thousands of gallons a day, every day—at SFO and LTN to meet the growing market demand,” said Tony Lefebvre, Signature’s COO. “SAF is the cornerstone of aviation’s answer to environmental responsibility. Creating an affordable alternative to traditional jet-A is vital to ensuring we’re able to help our customers reduce their carbon footprint.” He added that the company, the world’s largest FBO operator, plans to add SAF capacity at other locations over the coming year as it makes a commitment to fuel all private and business aircraft at SFO with blended SAF starting in the first quarter of 2021.

NetJets, part of the original announcement, which also included SAF producer Neste, took on the initial load of more than 1,000 gallons in one of its Bombardier Challenger 350s at SFO. As the primary launch customer, the fractional jet operator has agreed to purchase up to three million gallons of SAF through the Signature Renew program for its flights at SFO and, via a book-and-claim scheme, the company’s Columbus, Ohio headquarters.
