Government figures have shown that travelling by public transport is getting more expensive.
Bus and coach fares increased by almost 25% between 1997 and 2009, while the price of train tickets shot up by 13% in real terms, the figures from Transport Minister Sadiq Khan's commons reply showed.
However, Mr Khan had good news for motorists, revealing that the cost of running a car had fallen in the same period. He said the "real" cost of motoring, including buying the car, had dropped 14%.
Between 1980 and 2009, the cost of running a car has dropped by 17%, Mr Khan added. In the same period bus and coach fares rose 54% and rail fares increased 50%.
The cost of the average UK domestic one-way air fare, including taxes and charges, also went down, by 35%, between 1997 and 2008.
