United Airlines made history yesterday by becoming the first U.S. airline to begin use of sustainable aviation biofuel for regularly scheduled flights with the departure of Flight UA708 from Los Angeles International Airport.

The launch marks a significant milestone in the commercial aviation industry by moving beyond demonstration flights and test programs to the use of advanced biofuels for United's ongoing operations.

United has agreed to purchase up to 15 million gallons of sustainable biofuel from AltAir Paramount over a three-year period.

The airline has begun using the biofuel in its daily operations at LAX, storing and delivering it in the same way as traditional fuel.

To highlight this achievement, United will operate flights between Los Angeles and San Francisco with the dedicated use of AltAir Paramount renewable fuel for two weeks, while also integrating this fuel into its regular operations at the airport.
