I am pleased that the Minister supports lifeline flights, but he must recognise that the cost to the passenger of some essential flights is excessive, often because there is a monopoly supplier—there is no alternative. In contrast, bargain basement prices are offered on destinations where there is competition with rail. Does he not see merit in the Lib Dem idea of a cap on the cost of essential flights from monopoly suppliers, with a surcharge on those flights that compete directly with rail, both to encourage modal shift and to help to fund high-speed rail?
