The SAF deliveries commenced at San Francisco Airport in April, with United receiving 1.5 million gallons of SAF for departing flights, the remainder of United’s SAF supply will be used at Los Angeles International Airport and Amsterdam’s Schiphol Airport. London Heathrow Airport is expected to begin receiving deliveries of SAF later in 2023. Once the SAF is delivered to London Heathrow, it will mark the first time United would participate in London Heathrow’s SAF incentive program.
