asked the Secretary of State for Transport what is his estimate of the current cost per mile for an adult travelling by (a) car, (b) train, and (c) aircraft on an internal flight.
Overall averages for the cost per mile to individuals travelling by car, train and internal flight would be Seriously misleading because of the very wide range of costs for different journeys. For example, the direct cost per person for four adults travelling in a family car can be under 1p a mile whereas the total cost per mile for a large car used mainly on business with one occupant can be lop to 20p or more depending on the annual mileage. For train travel the fare is about 3p a mile for a second class day return and 8p a mile or more for a first class single fare. Fares for internal flights vary from just over 5p to over 20p a mile. Information about separate spending per mile by adults and children is not readily available.
