To ask the Secretary of State for Transport, pursuant to the answer of 26 June 2026 to Question 11220 on Aviation: Alternative Fuels, whether her Department has made an assessment of the potential impact of Sustainable Aviation Fuel Mandate compliance costs on (a) the cost of package holidays purchased in the UK and (b) the competitiveness of the UK outbound travel industry.

As previously stated, an assessment of the costs of SAF policies and the impact on air fares was conducted as part of the published SAF Mandate cost-benefit analysis.

The SAF Mandate is designed to protect against excessive costs being passed on to passengers with a buyout option for obligated suppliers, with a built-in review process so the Government can take action if necessary. How airlines choose to pass on costs to passengers will be a commercial decision for each airline. As such, it is not possible to predict how individual airlines will choose to do this or the impacts this will have on UK outbound travel routes.
