Flight100 is the first commercial airliner to cross the Atlantic using 100% sustainable aviation fuel.
  • Virgin Atlantic is operating the first transatlantic flight on a commercial airliner powered by 100% SAF.
  • SAF can be made from crops and used cooking oil, and is key to decarbonizing aviation.
  • But it costs more than double conventional jet fuel, and production is lagging behind demand.

The first transatlantic flight on a commercial airliner powered entirely by sustainable aviation fuel, or SAF, took off from London's Heathrow Airport on Tuesday morning.
