Worldwide diesel/kerosene biofuel production is too low. Last time airbus made a demo on 100% biofuel made from algae, they bought the output of a whole year to run a single long haul flight.
There is a reason they say Sustainable Aviation Fuel (SAF) and not biofuel. They also need e-fuel / synthetic fuel made from hydrogen in addition to biofuel.
