Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 8 July 2026 to Question 14435 on Aviation: Alternative Fuels, whether the cost-benefit analysis for the Sustainable Aviation Fuel Mandate modelled the potential impact of SAF compliance costs on (a) package holiday prices and (b) demand for outbound leisure travel from the UK.

The Sustainable Aviation Fuel (SAF) Mandate cost benefit analysis estimated the potential impact that SAF Mandate compliance costs could have on UK aviation demand. There was not a specific assessment of the demand impact on outbound leisure travel, or the impact on package holiday prices, as this will be dependent on how individual airlines and package holiday providers choose to pass on any costs.
