Today United Airlines is continuing its campaign to accelerate the uptake of Sustainable Aviation Fuels (SAFs) across the industry. The airline will run a Boeing 737 MAX engine on a blend of 100% SAF while it is flying from Chicago to Washington with more than 100 passengers onboard. This will be the first time that such a feat has been attempted.
It definitely is. Also, I believe that SAF will be the future of commercial aviation as a whole since it is more viable and far easier to implement and develop than hydrogen or electricity-powered aircraft.
