Just going back to public transport and MAN. Because MAN still has a big outbound leisure orientated pax mix, it will always find it difficult to get more to use train/bus to the airport. The once or twice a year bunch (of which there are many) look forward to their holiday and they will be damned if they are going to use public transport for the start of their well earned break. No, they splash out on a taxi or they drive and park. It's in a similar vein as to why onboard sales on MAN based aircraft are the best on any given airlines network.
