The cost of a return trip to New York is on track to rise by £40 as a result of incoming net zero regulations, according to figures from Virgin Atlantic. The extra burden on travellers is expected if the cost of sustainable aviation fuel (SAF) is passed on directly. Calculations by Virgin Atlantic, a pioneer in using the greener jet fuel, show that ticket prices would have to rise 6pc. For a return flight to New York that would amount to a £40 increase at current prices, based on two one-way fares costing about £350 each. SAF is a refined blend of waste oils, animal fats and ethanol from corn. The fuel is viewed as the most practical route towards reducing aviation’s net CO2 emission before completely new technologies, such as hydrogen propulsion, become available next decade or beyond. Airlines operating from the UK will be required to use at least 10pc SAF to power their flights from 2030, but with the fuel currently costing six times as much as traditional jet fuel, passengers face a potential jump in fares. Figures published by Flint Global suggest that by 2040, when the UK mandate will require a 22pc SAF blend, fares...
