It does seem that BHX doesn't market the ease of getting to the airport. In the centre of England and M6, M5, M40, M42 and close to M1 motorways. West coast mainline station, with Virgin lounge, bar and café shop ATM's etc. a terminal like warm environment and far superior connections than any other UK airport station. I've been to some of them and most are in no way remotely comparable to Birmingham International. However it does seem to me, from personal observation only, that the rail feed to the airport is growing. They should push this more especially as young people today seem to be snubbing car ownership.
