To ask the Secretary of State for Transport, what estimate he has made of the percentage change in real terms of the average cost to the individual of travelling by (a) private car, (b) bus, (c) train and (d) domestic aeroplane since (i) 1980, (ii) 1997, (iii) 2010 and (iv) 2015.
(a-c) The Department for Transport publishes statistics on travel costs, based on data from the Office for National Statistics (ONS), in the Transport Statistics Great Britain compendium. This is available from Table 1308 at the link below:
Please note this table gives absolute changes in the indices and covers 1987 to 2017.
(d) The costs of travelling by air are not available from ONS data. However, DfT estimates are available based on fare data collected from the Civil Aviation Authority passenger survey from 2000. The real cost of the average UK one-way air fare, including taxes and charges, covering domestic flights from 2010 to 2017 decreased by 22%. From 2015 to 2017 the real cost decreased by 7%.
