Taking the train to BHD
is a pain - the station is nowhere near as close to the new terminal as it was to the old one.
Easiest way: take the Airlink bus from BFS
to Europa Buscentre, then pick up the City Airport Airlink bus from there. The BHD
bus is every half-hour, £2 single.
Me, I'll often pay the extra to use BHD
, though - much nicer airport than the International, IMO.
